[Samba] Authentication fails sometimes

[Juergen Hasch]

Hi,

I'm running a Samba server with 2.2 CVS in a W2K domain with
 workgroup = DOM0
 security = domain
 password server = PWDSRV

Authentication works most of the time, but sometimes a user isn't
getting authenticated.
The password server seems to return NT_STATUS_PIPE_NOT_AVAILABLE.
What does this error mean ?

I have a small script which periodically tries "smbclient -L //puma"
and I get an error only very few times with no recognizable pattern.

Below is a level 3 logfile showing the problem:
