675 errors from other DCs?

[graeme_smith77]

Hi all,
recent slow replication led us to reboot our PDC emulator.

All seems to be going through but the Security logs shows 675 Account
Logon errors regularly.

Pre-Authentication failed:
User Name: servername$
UserID: domain\servername$
Service Name: krbtgt/FQDN
Pre-Authentication Type: 0x2
Failure Code: 0x18
Client address: IP address of server.

Our domain has grown over the past year or so - 33 DCs (around 25 being
GCs) but user numbers are fairly low (about 1500 user accounts).

Can anyone tell me why we are getting these errors please.

Regards

Graeme

Looks like that the password in AD for that computer account has either
becoome corrupted, or for some reason, the DC thinks the password isnt what
the computer thinks it is
