Title: Force Outlook to use closest GC to Outlook client

Both settings should work (but I guess that doesn’t help J).

 

Is the GC you are specifying in the registry keys definitely a working GC?   You can quickly check this by connecting to RootDSE on the DC using LDP.EXE.  It should show:

 

isGlobalCatalogReady: TRUE

 

Also, if your DC is pre-Windows 2000 SP3 and was made a GC but has not been rebooted since promotion, NSPI (the bit that Outlook and Exchange talk to on the GC) is not automatically enabled.  A reboot is required.

 

You might be able to see more of what happens at the time of connection by using Ctrl+right click on the Outlook icon in the task bar notification area and selecting “Connection status”.  Sometimes this can give you a few clues.

 

Failing that, you could try a netmon trace to see what (if any) traffic there is to the GC.

Subject: [ActiveDir] Force Outlook to use closest GC to Outlook client

 

Hope you can help me with this one.

This is the case: I am in an environment with one root domain and 4 child domains in it, based on country (4 countries). All users have an account in one of the child domains (the rootdomain is in fact empty and acting as placeholder).

Now when somebody from lets say childdomain A, is travelling to another country, for instance childdomain B and he connects with Outlook to his mailbox in childdomain A, he gets referred to the gc that is closest to his Exchange server. What I want is to get Outlook to connect to the closest gc to the Outlook client itself.

I know there is a KB article for this and I followed that:

http://support.microsoft.com/default.aspx?scid=kb;en-us;Q319206

According to MS the following key could be implemented to force Outlook to connect to the closest gc to itself instead of to the gc closest to the Exchange server being used.

HKEY_CURRENT_USER\Software\Microsoft\Exchange\Exchange Provider
Value name: Closest GC
Data type: REG_DWORD
Radix: Hexadecimal
Value data: 0x00000001

Anyway, that doesnt work. When I check I find out that Outlook still uses the gc closest to the Exchange server.

I even tried specifying a specific gc for Outlook to use. The registry key for that is also to be found in that same KB article:

HKEY_CURRENT_USER\Software\Microsoft\Exchange\Exchange Provider
Value name: DS Server
Data type: REG_SZ (string)
Value data: FQDN of the global catalog server

Still the same problem. Outlook keeps using the gc closest to the Exchange server.

Do you have any suggestions about solving this?

Thanks a million in advance.

Victor
