Re: [Exchange] Exchange keeps looking at a old DC Thank you very much for the tips. I haven't started digging into this today, but I'm going to start.
A little more information about this network. The previous IT Manager was fairly incompetent and not a good fit for the position. He was fired and I was brought in to fix some of the core networking issues and deploy a new VoIP system. I'm not really a Windows guy, but the owner of the place is a friend and he's pretty much begging me to see if I can work out the AD and Exchange issues they have been having.
More about the network:
This network as of now has 2 functioning DCs. Both are running on Windows Server 2003. There is only one Domain and one Forest. There is only 1 Exchange server and it's running Exchange 2010. Previously, Exchange was running on Exchange 2003. The previous IT Manager attempted an upgrade to Exchange 2010. From what I heard from the staff, it didn't go very well. Ideally, I'd like to move all the DCs up to 2008 R2, but baby steps. There also seems to be other issues. For example, I'm not able to access and modify the group policies. The GP snap in reads that it's not able to connect to Active Directory. Without taking the whole network down to start AD from scratch, I'm not really sure what to do.
I'm getting to the point of telling this guy that he needs someone who's an expert in this area to clean up the mess because form my perspective, it seems better to start the whole AD setup from scratch rather than try to fix this one.
