My windows 2000 domain controllers recently started generating alot of
675 errors - coming from exchange 2000 mail servers (running on windows 2000
servers or domain controllers - Active directory is 2000 mixed mode) as well
as windows 2000 pro client machines :



Pre-authentication failed:
User Name: server$
User ID: domain\server$
Service Name: krbtgt/domain
Pre-Authentication Type: 0x2
Failure Code: 0x18
Client Address: 192.168.0.5

Recent environment changes include:

switching exchange 2000 to native mode (last 5.5 server removed long ago but
only switched modes recently)

addition of 1st exchange 2003 server on windows 2003 server (ran domain &
forest prep as part of that - netdiag & dcdiag also ran clean )

enabled scavenging of stale dns records

additionally I get the following errors:

Any ideas why would be appreciated - I am posting in exch 2000 newsgroup also
