Hello. I'm a System Administrator on a network with 190 Sites. When I make diagnostic for domain partition replication with "repadmin" tool. I got some sites with old replication date. But it only show the GUID name for those old dates. For example my last diagnostic give back this: Caching GUIDs. .. ab6e1002-ac6c-47db-937b-c443cfbf12a1 @ USN 1385403 @ Time 2004-09-23 08:41:34 Santiago12-SiteSUC20200 @ USN 192519 @ Time 2004-10-02 22:49:23 b6db8e34-79d1-40fb-927e-fdd07f1653a5 @ USN 1026879 @ Time 2004-11-27 15:35:49 Some body know some way to make a query on Active Directory to resolve those GUIDs names to the "Site Name". Look that some sites appears with its name, like "Santiago12 Site". When I have only the GUID I can't know which one is my trouble site with this tool. Thanks

http://support.microsoft.com/default.aspx?scid=kb;en-us;325649 This will show you how to do it in reverse. You give the name and it will give you the guid. If you do this for all your sites then you should be able to match it up with your unknown guids.

Thanks cleonard, It could be a temporally solution. But this require a lot administrative work. And only will be temporally, becouse GUIDs usually change on active directory. It isn’t like the SID, that never change. If I have an Active Directory Object SID, I can find the CName making a custom query on active directory with SID=xxxxxxxx But it doesn’t work with GUID=xxxxxxxxx. I think that I’m not using the query on the correct way or something. It’s need to have a simple way to return the canonical name from the site having the GUID. But… How?

It is my understanding that objects are actually stored as globally unique IDs and that this GUID is a 128-bit number that is generated at the objects creation and are stored in the objects attribute object GUID and that they NEVER CHANGE.

Do you have any references that state that these GUIDs change?

Hello People, thanks for all your support.

There are many reasons for resets or changes on the GUID, for example this event ID:

Event ID: 1349 Source: MSExchangeDS
Category: Replication
Type: warning
Description:
The GUID on server (Server Name) has changed from a86a49730326d3118fb80000f806a267 (Server Name) to 0a964fd8e0d7d2118faf0000f806a267 (Server Name). This causes all replicas to be resynced from scratch.

The GUID is an global unique identifier name. But it is not permanent like the SID.

I already find a way to find an object having the GUID. But is not simple. At first I was trying to make queries with this kind of number: a86a49730326d3118fb80000f806a267. But it is erroneus. I must first convert the string format of the GUID and this is not to simple for me.

Does somebody know a better way to find an object only having the objectGUID?
