Hi All, We have EXchange 2007 server pointing to different GCs and DCs. Now one of the GC went down and we want to remove that particular GC from exchange server. Please let us know the setting to remove particular GC or DC from exchange. Thanks.Sunil Bansal.

Exchange should detect changes in available DCs/GCs during discovery topology every 15 minutes, you can verify the event id 2080 in Application event log. But make sure that Exchange is not configured with static DC/GC with Set-ExchangeServer anytime, you can run below cmdlet to get the status... Get-ExchangeServer ExchangeServerName -Status | FL Name,*controller*, *catalogs* You can post here 2080 event log if you get any doubt in it... Event ID 2080 from MSExchangeDSAccess http://support.microsoft.com/kb/316300 Amit Tank | MVP Exchange Server | MCITP: EMA | MCSA: M | http://ExchangeShare.WordPress.com

I got following output,Name : server01StaticDomainControllers : {}StaticConfigDomainController :StaticExcludedDomainControllers : {}CurrentDomainControllers : {dC names}CurrentConfigDomainController : domain nameStaticGlobalCatalogs : {}CurrentGlobalCatalogs : {GC names}I think we have configured with static DC/GCs. In this case, I think if any GC or DC go down. we need to change the setting manually on server. Please let me know if you have that setting to change and remove old DC/GCs manually from exchange 2007. Thank you very much for reply. Regards, Sunil Bansal.

But output doesn't show any static value. Name : server01StaticDomainControllers : {}StaticConfigDomainController :StaticExcludedDomainControllers : {}CurrentDomainControllers : {dC names}CurrentConfigDomainController : domain nameStaticGlobalCatalogs : {}CurrentGlobalCatalogs : {GC names} And are you able to find down GC in above Current* results (because you trimmed the original names so I couldn't figure out, you may put dummy names of current and down GC there so we can understand like an example) What's the latest event 2080 says in Application event log? Can you post it here too with dummy names?Amit Tank | MVP Exchange Server | MCITP: EMA | MCSA: M | http://ExchangeShare.WordPress.com

Yes, I can see the current domaincontrollers and Currentgloblecatalogs names in above output. Actually we had problem with BB server where the mail flow was stopped due to unavailbility of GC server but the problem was resolved after restart the server.

Hi Amit, I understand that there may be some thing else wrong with BB for having mails stopped problem. As I am not supporting BB. I dont have much information about it. But for learning purpose if we have configured/bind static GC/DC on server, how can we remove/change through command shall or from EMC. Thanks.Regards,Sunil Bansal.

You can not remove/change static DC/GC with EMC, you need to use EMS. Static* parameters ofSet-ExchangeServer need to set back to $Null to remove all static entries.
