I rebuilt the DB and it worked. However, it didn't go back to default it went back to after the first log in and there were existing logon accounts - I had to dig out the list of old admin passwords and (by trial and error) find the one that was in use at the time (which I eventually found).
Unfortunately, it's got one logon account that I don't want anymore and it won't let me delete it - it says the owner is the domain administrator and when i try to delete it it tells me that its either already logged on or is the services account. How can I delete it?
Thanks...:
