Hello everyone, I really hope someone can give me ideas on this one.

I have inherited a Windows 2000 Domain conisting of 4 Servers acting
as Domain Controllers ( a PDC and 3 backups). A problem that has been
happening for as long as I can remember, deals with any Software that
requires the use of a Domain Service account.

The symptoms, as best as I can describe them, revolve around the
affected application, no longer performing its designated function.
The accompanying monitor for the software, reports everything is OK,
and theres nothing unusual in the event logs, it just stops working.
My next step is to go into the MMC and take a look at the services
associated with the software. Sure enough, it's status is "Started."
The only way I can prove that there is a problem, (other than the fact
that the software isnt working) is to attempt to "Restart" the
service. After attempting to restart, it returns an error, to the
effect of "Could not start due to log on failure."

OK I know what you are thinking, but here is the weird part. All I
have to do, is goto that services "Log on" Tab, and retype the
existing password. I don't reset the account, I don't "unlock it." I
just simpley retype the same password that i typed in since the last
time the problem happened, and viola, the service starts.

I have ruled out a problem with the application as it occurs with ANY
software that uses a service account. Just to name a few we
experienced the problem with though: SMS, Cisco Unity, Brightmail,
Vertias NetBackup and Blackberry Enterprise Server.

If I didn't know any better, It seems like the services stop
submitting the password after a period of time. Each service that uses
a domain service account, experiences this at least once a Month,
sometimes twice.

Now the administrator before me was a bit of a security nut. Are there
any settings that might be defined in the security policy that would
cause this type of problem?

ANY guidance would be appreciated.

Thanks in advance,
Ian

How often are passwords required to be changed in the domain policy?
Are all of these accounts configured to be able to log on as a
service, control their own passwords or have the passwords never
expire?

I would do a health check of all the domain controllers, checking the logs.
If one DC is having problems then I could see how a service could get hung
up when it hits that DC, and then be fine if you restart and hit a different
DC.
Of course this depends upon your site design as to whether it's likely to
hit multiple DC's or stick with one as much as possible.

Regarding someone having set security policies, you really should check and
see if any GPO's have been setup, and if so what's in them. If you use the
newer GMPC it's pretty easy to see what settings have been applied in
a particular GPO.
