Raising functional level problem; service is busy
I'm having a little trouble with raising the function level of my server.
I have 1 DC atm, 2nd one died over xmas, replacement has been bought and is running server2008r2.
Current DC/Forest is running in Windows 2000 native mode, and is a server 2003 box.
Old DC that died had no functions, all FSMO's are on the currently running DC. Old DC does not appear in ADUC, or in ADDT.
When I try to raise the functional level of the domain, it moans about the Domain service being busy.
The server is in use; there are users logged on/using it etc, I could disconnect it if this is what is stopping it from working.
There was some out of date records in the DNS, I have removed all references to it as a naming server, and removed all records i could find in the ip or name of the old server.
The replacement is not yet on the domain ( I did have it as a member for a bit, I've since removed it just in case I'd broken something.)
Anyone got any bright ideas?
If disconnecting the server and stopping people logging in will fix this then great! But I want to make sure before I disconnect everyone to do it.
