DATABASE CORRUPTION IN EXCHANGE…PRT2

B00M3R John Bostock Profile: B00M3R

In the first part of this corruption post I spoke of what happens when an Exchange database goes corrupt on you. I also mention it can happen at page level, database level or store level. I mentioned hardware as well which will cause problems.  This post will concentrate on the 1018 error.

The common type as mentioned of database corruption is at the page level. You’ll get heaps of different error messages the can potentially relate to this type of corrupt database. The most common being 1018, now we have all seen the 1018 Jet_errReadVerifyFailure (havent we?) Most of the time this error indicates that the page has the incorrect checksum value or the page number is incorrect. Microsoft Exchange will begin reading the database page by processing the page number; this is so it knows its reading the correct data. If for some reason the number is different from the expected number, then yes you guessed it exchange generates the 1018 error.

Otherwise Microsoft Exchange will calculate a checksum value for the page then verify the calculated value and make sure it matches the stored checksum value. If it does match then the page is assumed to correct and valid otherwise, yes again the 1018 gets generated.

Should I take the 1018 seriously?

The 1018 is often a warning that bad things are on their way. Exchange is trying to tell you that the database has failed once and may go again. Normally they will be non fatal failures; however future failures could be worst and corrupt the store.

So if you haven’t worked it out already the 1018 is associated with an individual page within the database rather than the whole database. The 1018 is normally not fatal and some may take it as of no interest at all because Exchange has been known to generate this error with infrequently used data such as in a deleted items folder or just a plain old blank database.

What do I do with the 1081?

Try and find more about the error before trying to repair, first instinct is to fix but learn more about it first. This way you can try and determine exactly what data was affected and how fatal the failure is, also what’s the likelihood of it happening again.

In the next section we will look further at the 1018 but in the meantime check out some of the links on the 1018 error.

DATABASE CORRUPTION IN EXCHANGE

B00M3R John Bostock Profile: B00M3R

If you’ve been in this industry for many years as most of us have and worked with the different variants of Exchange Server I’m sure you would have come across a corrupt Information Store at some stage. In the upcoming blogs I’ll show you the most common type of database corruption and we’ll talk about what we can do to fix each type.

Most of the time database corruption refers to ….the data in the store becomes corrupt/invalid or unreadable. If the wrong data is written to the database or written to the wrong location or physically damaged after being written.

Now..How does this happen? If the hard disk has many bad sectors or becomes physically damaged, transaction logs get read incorrectly and the update is incorrect. I’ve also had it happen when power failures cause shutdown. Whatever the reason you most understand there are several places corruption can occur?

The page Level. – This is an individual place inside the database where data is stored. Miss read Tran logs or power failures normally cause this and you’ll find this type common. Most corruption issues will be page level corruption.

The Database Level. – This is where the individual pages are OK but the database file is invalid. Like if the file header is damaged or part unreadable. This problem at the database level often means the jet database cannot interact correctly with the associated EDB file.

The Application Level – This refers to the entire store itself the database is relational which means that the databases depend on each other for info. Example Although Exchange 2000 doesn’t have directory service it depends on the Active Directory.

Also you must consider other possibilities too. If Exchange isn’t working correctly then don’t always presume it’s the store or the database is corrupt. Exchange depends on Active Directory, IIS and Windows and of course the hardware. So if one of these is having issues then Exchange will be too. If your server has a memory related problem, then items stored in memory may be corrupt. Therefore, if Exchange sends the system to send the contents of a particular memory block to the database or to a transaction log, then the database or transaction log would become corrupted as a result of the memory problem.

You can see that the way Exchange databases are layered and all the components that depend on each other leaves heaps of room for issues.

Recipient Policies What Are They?

B00M3R John Bostock Profile: B00M3R

Recipient Policies What Are They?

Recipient policies are organisation wide objects held in the “Recipient Policies” container – a sub container of Recipients. When you install Exchange the program creates a default policy and you can then create as many policies as you want to after. Although you must keep the default policy and you cannot delete it.

What do they do?

Set a default value for the domain used by Exchange to reference files via IFS. (IFS provides access to the Exchange information store by using Win32 file system APIs)Generates email proxy address. RUS generates and sets email addresses on new mail enabled objects but you define the format for the addresses and the type of proxy address that RUS generates through policy.Controls how the mailbox manager processes mailboxes.

Enables SMTP virtual servers to accept incoming mail. When you make an installation of Exchange the virtual servers will accept email from the domain defined in the default policy, but you add policies to cover additional domains if you require.

The Recipient Update Service (RUS) is responsible for creating and maintaining E-Mail Addresses in your Exchange Organization. The Recipient Update Service creates an Entry (Recipient Update Service (Enterprise Configuration)) for the entire Exchange Organization for modifying objects in the Configuration Container Partition in Active Directory and one RUS for every Exchange enabled Domain in this Forest.

Exchange Install.After install there is one default policy created called “Default Policy” This policy contains Proxy address for the default SMTP domain and one for X.400 – You can add additional Proxy addresses to the default policy or have different Recipient Policies for different users.Note:If you want to remove old or unwanted E-Mail addresses, you must either remove the addresses manually in Active Directory Users and Computers or use an automated process. Or you can use LDIFDE.

Tools That Are Used with Exchange

B00M3R John Bostock Profile: B00M3R

In addition to Microsoft Management Console (MMC) snap-ins, Exchange System Manager, and Active Directory Users and Computers, there are many tools that you can use to manage and troubleshoot a Microsoft Exchange Server 2003 organization. Some of these tools are installed with Microsoft Windows, some with Exchange, and others are at the “Downloads for Exchange 2003″ Web site (http://go.microsoft.com/fwlink/?LinkId=25097). The following table lists these tools. However, be aware that not all tools are supported by Mr Gates.

I will talk about these tools as I progress through my Blog.

NOTE: Some tools can cause serious, sometimes irreversible, problems if they are used incorrectly. Before you use tools in your production environment, always become familiar with them on test servers first.

Message tracking event IDs in Exchange Server 2003

B00M3R John Bostock Profile: B00M3R

Here are some of the event IDs that are logged to message tracking log files. You can enable message tracking logs to track or to troubleshoot the flow or status of a message in Exchange Server 2003 as shown in previous blog. You can record information about the sender, the message, and the recipient. If you want to log more detailed information, you can also record the subject line of messages.

By default, the tracking logs are located in the C:\Program Files\Exchsrvr\YourServerName.log folder. Each daily log is named in the yyyymmdd.log format according to the date that the log was created. The file name date is in Coordinated Universal Time (UTC). Here is a list of event ID’s and there meaning. You can import this log file into Excel which makes it easier to read as opening the text file is too busy.

A few FAQ’s
Q1: When a message is generated in the system for the first time, what event is associated with that message in the tracking log?
A1: There are different events for different message submission paths to Exchange Server 2003. For example, for messages that are submitted through the SMTP component, the first event ID in the tracking log is 1019. For messages that are submitted through the Store component, the first event ID in the tracking log is 1027.
Q2: Is there one event ID that covers the creation of all messages and that only appears one time per message?
A2: There is no one event that covers the creation of all messages because messages can be created in various ways by various clients, remote servers, and pickup directory. It would make no sense to use the same event for all these code paths. Or, it would be impossible to use the same event for all these code paths. However, event 1019 is logged when any message enters Inetinfo-side transport processing. The tracking log may frequently contain multiple 1019 events that have the same message ID. For example, this may occur if the server is restarted multiple times during a period when the remote destination for the particular message is down. On each restart, the message is resubmitted, and event 1019 is logged. This is expected behavior.
Q3: Why are there multiple 1020 and 1031 events that are logged for the same message ID?
A3: This is expected behavior. The same message ID can be transferred out multiple times. When the same message ID is transferred out multiple times, events 1020 and 1031 are generated.

Event Number Event Type Description
0 Message transfer in The message was received from a server, a connector, or a gateway.
1 Probe transfer in An X.400 probe was received from a gateway, a link, or a message transfer agent (MTA).
2 Report transfer in A delivery receipt or a non-delivery report (NDR) was received from a server, a connector, or a gateway.

8 Report transfer out A delivery receipt or an NDR was sent to a server, a connector, or a gateway.
9 Message delivered The message was delivered to a mailbox or a public folder.
10 Report delivered A delivery receipt or an NDR was delivered to a mailbox.
18 StartAssocByMTSUser  
23 ReleaseAssocByMTSUse  
28 Message redirected The message was sent to mailboxes other than the mailboxes of the recipients.
29 Message rerouted The message was routed to an alternative path.

50 Gateway deleted message The administrator deleted an X.400 message that was queued for a gateway.
51 Gateway deleted probe The administrator deleted an X.400 probe that was queued for a gateway.
52 Gateway deleted report The administrator deleted an X.400 report that was queued for a gateway.
1000 Local delivery The sender and the recipient are on the same server.
1001 Backbone transfer in Mail was received from another MAPI system across a connector or across a gateway.
1002 Backbone transfer out Mail was sent to another MAPI system across a connector or across a gateway.
1003 Gateway transfer out The message was sent through a gateway.
1004 Gateway transfer in The message was received from a gateway.
1005 Gateway report transfer in A delivery receipt or an NDR was received from a gateway.
1006 Gateway report transfer out A delivery receipt or an NDR was sent through a gateway.

1015 SMTP report transferred In A delivery receipt or an NDR was received by the Internet Mail Service
1016 SMTP report transferred out A delivery receipt or an NDR was sent to the Internet Mail Service.
1017 SMTP report generated A delivery receipt or an NDR was created.
1018 SMTP report absorbed The receipt or the NDR could not be delivered and was absorbed. (You cannot send an NDR for an NDR.)
1019 SMTP submit message to AQ A new message is submitted to Advanced Queuing.
1020 SMTP begin outbound transfer A message is about to be sent over the wire by SMTP.

1024 SMTP submit message to cat Advanced Queuing submitted a message to the categorizer.
1025 SMTP begin submit message A new message was submitted to Advanced Queuing.
1026 SMTP AQ failed message Advanced Queuing could not process the message. The message caused an NDR to be sent, or the message was put in the Badmail folder.

Exchange Message Tracking – A Great Tool!!

B00M3R John Bostock Profile: B00M3R

Exchange has a great feature called message tracking that enables you to track messages. It works for both directions inbound/outbound – it also does internal messages. This function has a low overhead so I leave it enabled so I can get my hands on the info when I want,  although I do have a large amount of emails that pass through my organization on a daily basis so I set log removal to be low.

—————————————————————————————————————————————————————–

Here is the scenario. Your Boss calls at the wrong moment as per usual raving about a SUPER important email message that never got delivered. So what do you do? This is when you need to know how to use Message Tracking so let’s have a look at how.

How to Enable

1.       Open ESM go to servers
2.       Right click on the server and choose properties
3.       Select these options “enable subject logging and display” “enable message tracking”
4.       “Remove log files” This option set to 30 days which is long enough. If you have massive traffic consider lower times say 7-10 days.
5.       Also check out the location of the log files. Keep them away from the main store on a separate drive if possible.

Now mine looks slightly different because I do mine through a server policy as I have multiple Exchange servers. Although greyed out you can see the ticks and where I store them.

Now let’s look at Tracking Messages.

Once tracking has been running for a while you will have collected some information, then we can track messages. Let’s look at how

1.       Open ESM and then go to tools
2.       Scroll down to Message Tracking Center
3.       Choose the server you want to track the message from. This of course will be the server that the user has his or her mailbox on, depending on whether you want to track inbound or outbound messages.

At this point we can search even though nothing else is configured. But this will result in heaps of results up to a max of 1000 every message since midnight will be processed. Best case – use the other fields to narrow the search results. Once the system finds the message you can double click it which will show what exchange did with the message.

Tracking log files will be stored (by default) in a folder located at x:\Program Files\Exchsrvr\servername.log, where x is the volume you have installed Exchange Server onto. Inside this folder you will find a text file for each day that logs are being retained for. You can open these files and work from them if you want, but I would recommend doing it in Excel as the files are tab-delimited and very hard to sort through otherwise.  

Ok so we have a great way of searching and finding out what has happened with an email. Now that’s it but we can advance things a bit by utilizing third party tools and REALLY bringing Message Tracking ALIVE.

Check out these links for advanced use of Message Tracking. If you search the web you will find various software, some users have created scripts to work with these logs – Just make sure you test them and not in your live enviroment :-)

Uninstall Exchange Server 2003

Firstly I need to apologize for the delay between posts, I have been attending to some business which kept me away and will acknowledge next time should I expect a large gap again.I’m going to get straight into the correct way to uninstall Exchange 2003 from a server. I have a systems Administrator who has this task in hand and I’ve done this for him and others.
Let’s do it!

You must ensure you meet the prerequisites before you attempt this and they are as follows:

  • If you have Exchange Full Administrator permissions at the administrative group level, you can uninstall Exchange Server 2003, provided that you have permissions for the administrative group to which the server belongs.

  • If there are any mailboxes assigned to a storage group on a server, you cannot uninstall Exchange Server 2003 from that server. In this case, you must either move or delete the mailboxes before you can uninstall Exchange.

  • You cannot uninstall Exchange Server 2003 from a server if it is the only server in your organization running the Recipient Update Service. Instead, you must first use Exchange System Manager to enable the Recipient Update Service on another server.

  • You cannot uninstall Exchange Server 2003 from a server if it is the only server in a mixed administrative group that is running Site Replication Service (SRS). Instead, you must first enable SRS on another Exchange server.

  • You cannot uninstall Exchange Server 2003 from a server if it is a bridgehead server for a connector and there are other Exchange servers in your organization. Instead, you must first designate a new bridgehead server.

  • You cannot uninstall Exchange Server 2003 from a server if it is the routing master and there are other Exchange servers in your organization. Instead, you must first designate a new routing master.

Now before you remove the server from a production environment that has multiple servers in the administrative group, understand that you need to know all the servers roles that are held by this machine. Make sure you move your roles to other machines. Example: If the server is listed as a bridgehead server on a connector you will have to move this before uninstall will work. Failure to do this could cause many things including the following:

  • Mail flow may stop if the server is a bridgehead server.

  • Mail flow will be totally screwed if the server is the routing group master.

  • Outlook issue and OWA issues so confirm and check before attempting the uninstall.

Before you remove Exchange 2003, you must disconnect all mailbox-enabled users from the mailboxes on the Exchange server. It is not possible to remove an Exchange Server when it has mounted mailboxes. If you are getting this error check out the following One or more users currently use this mailbox store. These users must be moved to a different mailbox store or be mail disabled before deleting this store”A good way to try to find these missing users is to use Active Directory Users and Computers. Here’s what to do:

1. Run ADUC.(Active Directory Users and computers – come on!)

2. Right-click your domain at the top, and choose Find.

3. Click the Advanced tab, and then choose User from the Field button.

4. From the list of attributes displayed, choose Exchange Home Server.

5. Set the Condition field to Ends With and then type your Exchange server name into the Value field. Click Add to add this value.

6. Now click the Find button, and hopefully you’ll see the troublesome user listed in the results window.

You should then be able to remove the Exchange attributes from these user accounts and proceed with the un install.

To uninstall Exchange Server 2003

1. Log on to the server from which you want to uninstall Exchange.
2. Click Start, point to Control Panel, and then click Add or Remove Programs.
3. In Add or Remove Programs, select Microsoft Exchange, and then click Change/Remove.
4. On the Welcome to the Microsoft Exchange Installation Wizard page, click Next.
5. On the Component Selection page, in the Action column, use the drop-down arrows to select Remove, and then click Next.

Follow the bouncing ball and Exchange should uninstall.
