Have you also moved the FSMO roles to the new server as well ? Otherwise your system will not know the full topology of the AD.

Hi All, Can somebody explain to me how the three interact. I have been reading up on some postings and would like some clarification as to how they are interrelated. We have 2 Domain Controllers(DCs), A and B and Exchange as a member server. A is setup as the Global Catalog. We added a third DC, C, to replace A. We promoted C as a global catalog and remove Global Catalog function from A. We forced replication between the two DNS servers, A and C. We then shutdown A. That's when we noticed that users complained that Outlook failed. Can somebody explain to me why this happen? We had to bring back server B to get this fixed. >From what I have read, this is how I assume it works. Please correct if I am mistaken. When a Outlook MAPI client connects to exchange, it queries the Exchange server for the preferred Global Catalog. Exchange replies with the closest GC it knows of and the Outlook client caches the information. This can be seen on your local computer's registry. If for some reason, the GC were to go down, then it would not work. Exchange only knows about the Global Catalog that it boots up with. Any new GC added afterwards requires a reboot or the System Attendant to restart. The list of GCs avaiable for Exchange to refer Outlook clients reflect the state of the network when Exchange was booted and is not dynamically updated. >From our scenario, could it be that because Exchange didn't know about our new GC, Outlook failed? I just want to decommissioned the A server from our network. I am trying to understand the interdependecies between Exchange and Windows 2000 AD. Any help would be greatly appreciated. Thanks! _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] ------------------------------------------------------------------------ This e-mail and any attachments may be confidential and/or legally privileged.
