I have a Windows 2000 server RAID 5 DC with Active Directory which is my main file server as well. I have a second DC with Windows 2000 server and Active Directory.
This is an internal LAN only - no outside connections.
I uninstalled Exchange because we don't use it but it made our IIS website inoperational so I restored the system state and all was fine.
A few weeks later I tried a manual removal of Exchange which included deleting the Exchange object from AD. Again removing Exchange wiped out our IIS website so I restored system state. When AD replicated the Exchange object was wiped out, although it did return with the system state restore at first.
A lot of other things happened as well - some users could no longer log on to that domain, some could not access some of their file shares, the login scripts no longer work although they are there in sysvol, AD on the main server was sluggish and took forever to make changes, the main DC seems to think it's no longer a DC. The 2nd DC cannot access the main DC at all - says path not valid.
I have 2 NT servers on 2 different domains and those logons went strange too - some staff can't access file shares, etc. Also, one day someone can access a file share and the next day he can't. Just too many oddball things happening.
I turned off the 2nd DC and tried a system state restore of the main DC to see what would happen. No one could log on. Even those with administrator rights were alerted that there was no DC to log them on although they could get around the network. When I turned the 2nd DC back on, both servers went back as they were with all the same strange problems.
Don't know if removing the Exchange object could wreak such havoc and if I should authoritatively restore it or if I should remove AD from the main DC and demote it to a standalone server and go with just one DC (currently the 2nd one).
Everything else seems fine - services are on that should be on.
I am not trained - all I've learned is on the Internet, mostly Microsoft's website - I can usually resolve any problem but this one's a bit too much.
Can anyone help me with this?
