Saturday night i decide to upgrade our windows 2000 DC /exchange 2003sp2 enterprise edition.
I backup it up and run the adprep stuff. Run the install, goes like a dream. I login and look around to make sure everythings ok and i notice i can't see our member server, (win2003 standard/exchange 2003 enterprise). I login to it and can ping the DC and can also ping externally, by name and IP address, but i can't login to the domain only locally. When i try to login to the domain it tells me i supplied a bad argument.....never seen that one before.
So basically i think my dns is screwed and maybe the computer account so i pulled it out of the domain and tried to re-join with the dns name. No joy, no dns could be found. However, i could join using the netbios name. However, no matter what i did i could not get this member server to use DNS at all....i spent most of today tyring to get it to work as it has 80% of people mailboxes on that box. I have a system state backup + a full exchange backup and was wondering if i could go ahead and restore the server. Will there be a problem as the 2000 DC no longer exists as its been upgraded to 2003 sp2
Any ideas on the next move?
