You need a GC in the domain that Exchange expects to find it. You have two RUS definitions (should) one for the root and one for the other domain. You also have DSACCESS which will find the GC's available and pick one. If it picked the root GC, it would have some issues, but those issues would be different than just changing email addresses. If the RUS was the problem, changing an email address would be an issue until it came online.
I'm guessing that a bigger problem is DNS. How many DNS servers are defined for the Exchange server and where are they located in respect to the domains? It's possible it's just a GC/RUS issue though. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Pelle, Joe Sent: Friday, October 01, 2004 3:31 PM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] Active Directory w/ changes to Exchange Thanks for all the posts! We have an additional DC/DNS server in the ROOT but it is NOT a GC. That being said... I am assuming that's why I couldn't make my changes.... the GC was unavailable for the root. Correct?

Depends on the rest of the details of their environment. Having a single instance of DNS is not a recommended way to go about things and that may not be the only detail we need to make a suggestion. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Salandra, Justin A. Sent: Friday, October 01, 2004 1:08 PM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] Active Directory w/ changes to Exchange So really the answer to their issue here is to setup another GC/DC that is also DNS and point the exchange server to the child domain DNS and configure that DNS to do a forward lookup to the root DNS Servers. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Kern, Tom Sent: Friday, October 01, 2004 11:37 AM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] Active Directory w/ changes to Exchange Exchange(dsaccess) needs to look into the root dns to find a gc to begin with. If the root dns is down, exchange can't find a gc to write to or lookup address or where a email is supposed to go,etc If exchange can't find a gc, the info store will not start. -----Original Message----- From: Salandra, Justin A.

Nothing. The root DC was not available, and you are trying to write information to Exchange. The write operation will mostly happen at the Exchange Org level, depending on what you are writing. Since the org is at the root of the forest, there was nothing to write to.

I had an incident today that I really can't quite understand - please help... Background: I have an empty root domain and a child domain. The child domain has an E2K3 server in it. The E2k3 server has its primary DNS point to a DC/DNS server in the child domain and its secondary DNS points to the empty root DC/DNS server. Situation: The empty root DC/DNS server had a power failure (we have other servers in this domain). During the time when the empty root DC/DNS server was off I had to make changes to a particular users email address. I was unable to make any changes and received an error: the server is not operational - Exchange Extension. After getting the empty root server back online I was able to make changes and everything is fine. Probably something simple - BUT WHAT AM I MISSING? Also, on a different note... I was hoping that you all could suggest some patch management solutions that you use. I don't know if this request is bad etiquette or not... if so, please email me offline with info. We're in the middle of finding a good patch management solution for our servers and I was hoping to get some direction on good software from the field. Thanks in advance!
