computer name same as server name in active directory

Hi!

what if i’ve been dumb enough to use the server name on a new computer…

I corrected this now… But now Active Directory, domain controller and Exchange are nuts!

In event viewer I this error:
MSExchangeSA, Event ID 1005, Unexpected error Logon failure: unknown user name or bad password. Facility: LDAP Provider ID no: 8007052e Microsoft Exchange System Attendant occurred. DSAccess, Event ID 2114, Process INETINFO.EXE (PID=1628). Topology Discovery failed, error 0x80040952.

Any help?
