Have run netdiag /v and redirected to a .log file. Only
one error that I was able to find. Here it is:

Kerberos test. . . . . . . . . . . : Failed

[FATAL] Kerberos does not have a ticket for TS02$.

This is running on a Terminal Server. We have five
servers running WIN2000 Server SP3: two DCs/GCs, one
member server as the File/Print Server, one member server
running TS and one member server running Exchange 2000
SP3.

The last entry is a workstation in our environment (
running WIN2000 Pro SP3 - small chance running SP4 ).

Additionally, in another section there were also a very
high number of failed connections ( something like
1800 ). The other server had either 0 failed connections
or 10 at the most. Not sure how to diagnose this.

Anyone have any pointers?

TIA,

Tom
 
Hi Tom
We get the Kerberos ticket drop outs on servers sometimes
I normally would log on to the computer with an admin account
run a at job to open a interactive command window under the system account
context
at time /Interactive cmd.exe
Then view the tickets using Kerbray.exe, ran from within the cmd window this
allows you to view the computers tickets and not your own.
You can then purge the tickets
I would then use SETSPN -L to check the spns were registered correctly.
if not then register them using setspn -r you can use the a switch to add an
arbitrary SPN
also check the workstation is in time sync with the DC as this can cause
Kerberos issues check the dcs are in sync also.

PS
I meant server not workstation, and by sync I mean time sync if its out by
more than Kerberos allows then you will have problems
Q216734. I believe shows setting an external authoritative time source with
the dc that performs the PDC emulator role, (normally the first installed dc
in the domain unless you have transferred the role)
