DynDNS.com

Nathan Simon Nathan Simon Profile: Nathan Simon

Does it bother you when your home IP changes or you just can’t remember what it is and you want to connect to your router, RDP, or FTP. What can you do? Not much until you get home and check whatismyip.com…

Well there is something you can do, its called DynDNS.com they offer something called Dynamic DNS Free, just create an account, pick a hostname, ie nathantheitguy.homeip.net (this doesn’t exist btw), and save it. Now you only have to remember the name you created, this wont stop the IP from changing and you would have to continue to update it from time to time, unless you have a router like my Linksys which has a section in the setup where you can specify a DYNdns username and account, when the external IP changes, the router logs into DYNdns and changes the IP for you, sweet! Now all you ever need is just your name, nathantheitguy.homeip.net.

I will warn you though that DYNdns is free and as such you must login from the web once a month to confirm that there is a human managing the account. failing to do so and DYNdns deletes your account. The router login does not actually hit the website. A paid account, 15$ US, will eliminate the need for you to login, Dynamic DNS Pro adds a variety of enhancements and additional features to Dynamic DNS Free which are detailed on the Dynamic DNS Pro page. Please check out the links for full details, they have alot to offer.

vSphere 4 and Windows Server 2008

Nathan Simon Nathan Simon Profile: Nathan Simon

Here is another quick one for you all…  When creating a Windows Server 2008 Virtual Machine, do not enable paravirtualization, I know you want to, but whilst using vSphere, you will not be able to install the PCI Memory Controller Interface(you will be prompted to find drivers for this device, if you enable paravirtualization in the virtual machine settings). Its is only supported by certain Operating systems… now if you are using Hyper-V enabling paravirtualization will work. Just an FYI.

Installing Exchange 2003 on Windows Server 2008

Nathan Simon Nathan Simon Profile: Nathan Simon

Here’s the deal, Exchange 2003 will not work and cannot be installed on Server 2008, although if you have a Server 2008 Domain Controller, you can have an Exchange 2003 Forest. I hope that clears up some issues quicker then, say… Nathan installing Server 2008, attempting to fulfill the prerequisites of Exchange 2003 and not able to… :)

Blackberry Curve 8900 Smartphone

Nathan Simon Nathan Simon Profile: Nathan Simon

Well, I said I was going to be one of the guys that bought a Palm Pre, but fate stepped in and dealt me a Blackberry Curve 8900 Smartphone, and what a beauty she is, with its crisp and clear screen(480×360), to its speedy WI-FI connection, and its awesome camera (3.2 MP), I am very happy man. I have had the phone for less than a month, but its truly is an amazing phone. I had unplugged it from the charger yesterday am at about 3am(don’t ask me why I was up at 3am on a Saturday night and not out!) and haven’t plugged it in yet and its 10:15pm on Monday evening. WI-FI and Bluetooth were also on the whole time. One of the things I did was turn the brightness down on the Curve 8900 from100% to 20%, you barely notice a difference yet, apparently it nets you 25+% battery life… if you interested in reading about the full specs check it out here.

Another thing to mention is “BlackBerry App World” if you haven’t installed it yet, you should do so now… check it out here.

The Curve 8900 is a GSM(non 3G) phone, for you CDMA(EVDO) people, there is a new smartphone that has already shown up in Canada, its called the BlackBerry Tour, check it out here. Judging from the specs it seems that it is 3G capable, so I am guessing that there will be a GSM “3G” version that we could just swap out our SIM cards and start using the new “Tour” also.

Virtualization in General

Nathan Simon Nathan Simon Profile: Nathan Simon

Hey there folks, well I know 80% of the worlds population have an idea of what virtualization is, what it does, and why we all should get on the bandwagon… but there are some out there that still do not have a clue what VMware, Microsoft, and Citrix are doing with virtualization. Since there are those with questions, I thought I would provide some links for those people.

The first link I am providing is from one of my favorite resources in the world. Petri IT Knowledgebase by Daniel Petri, I wont get into why this is an important resource as many of my readers will already know. The link is for an article that David Davis wrote about Server Virtualization, here’s an insert from the beginning of the article…

“There are many types of virtualization- server, network, storage, and more. In this article, we will demystify these complex terms, explain what they can do for you, and name specific products that provide these functions. So prepare for the smoke to be cleared…” read the rest here.

The second link is a to a video that might be helpful to some readers, and maybe a waste of 3 minutes for some, hey at least its only 3 minutes! “Information Technology Explained in 3 Minutes of Less : What is Virtualization” check it out here.

Anyways, if I help shed some light on virtualization for at least a couple people I’ll be happy! :)

Mcafee 8.7i Install/Upgrade Failure

Nathan Simon Nathan Simon Profile: Nathan Simon

Okay, so you have a server/workstation and your upgrading McAfee on it manually… when installing the app, the services decide to fail to start… you see these(just below) in event viewer, what do you do? Well its pretty easy… just scroll down for the resolution…

Log Name: Application
Source: McLogEvent
Date: xxxxxxxxxxx
Event ID: 5004
Task Category: None
Level: Error
Keywords: Classic
User: SYSTEM
Computer: xxxxxxxx
Description:
Could not contact Filter Driver.
Error = 0×7d1 : The specified driver is invalid.

This issue is caused by a bad value in the registry.  Basically, in the old NAI installers, for some unknown reason, the entries in the registry point to the wrong locations, well not wrong, but imcomplete as far as the NAI 8.7i installer is concerned.

The fix? Easy.

run REGEDIT

Navigate to HKLM\System\CurrentControlSet\Services\mfebopk* then
Navigate to HKLM\System\CurrentControlSet\Services\Mfeapfk* then
Navigate to HKLM\System\CurrentControlSet\Services\Mfeavfk*

* Modify the ImagePath to be the full path to the driver– for example change:
“system32\drivers\mfebopk.sys” to “C:\Windows\System32\Drivers\mfebopk.sys”

The service should now start.

WSUS and Me

Nathan Simon Nathan Simon Profile: Nathan Simon

Well today I had quite the fight with WSUS, maybe i just wasn’t full focused today or something, either way, I finally got it working, the Default Domain Policy was over-riding my Organizational Unit “Domain Controllers” I basically blocked inheritance from Group Policy and set up a specific Group Policy Object specifically for my OU “Domain Controllers”

There was one website which helped me out in ‘forcing’ WSUS detection, normally one would type “wuauclt /detectnow” but at the time it didnt seem to work, so i utilized a tool called WSUS – DETECTNOW 2.0 which basically performs the same thing except you can also trigger detection for approved updates and can reset SusClientId too.

One wouldnt normally have to force a WSUS Detection if the companies Group Policy was configured properly though, this just speeds up the process :)

Windows 7 “Family Pack”?

Nathan Simon Nathan Simon Profile: Nathan Simon

Yeah you heard me, Microsoft is rumouredto have said that you may purchase one Family License copy of Windows 7 to install on, and up to 3 PC’s, that will be used in the same household. This may make it much more appealing to upgrade all PC’s at one time. Windows 7 is still slated for an October release, the 22nd to be more precise. I’ve been running my evaluation copy of Windows 7 ever since it was available and I am very pleased with the results.
