[ActiveDir] Active Directory w/ changes to Exchange

[Pelle, Joe]

Hello all!   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!   Joe   This message may have included proprietary or protected information.  This message and the information contained herein are not to be further communicated without my express written consent.
