[Samba] Intermittent problems connecting to Samba share-Domain Ctlr issue

Hi everyone,

We've been having intermittent problems connecting to Samba shares from Windows machines. I wrote a test program that tries to connect to the share and get a list of all of the files in it. It tries to do this every second. On some occasions this test program succeeds 14 times in a row before failing. It then fails once, and then succeeds 14 or so more times. It keeps repeating this pattern. Other times, this test program can consistently connect to that same share every second for over an hour.

The error in the log seems to indicate that the problem happens when the Samba machine is talking to the Windows Domain Controller to authenticate the user.

Here's the error from from the Linux machine's syslog(PGIDomainController is our Windows Domain Controller):
-----------------------------------------------------------

-----------------------------------------------------------

We've also seen this block of error msgs:

Any feedback on this would be greatly appreciated.
