Hi All,

come acrross a curious issue with 3.0.1-2 from Debian unstable. Looks
like a bug of sorts to me...

Have a PDC configured and basically working well, apart from single
recurrent issue that keeps popping up in the logs below, related to
failure or breaking of remote procedure calls.

The pipes more often break when using the UNC path as opposed to IP.

couldn't find service netlogon
[2004/01/29 10:20:34, 0]
  failed to decode PDU
[2004/01/29 10:20:34, 0]
  process_request_pdu: failed to do schannel processing.
Users can logon, group security settings are honoured, passwords can be
changed etc etc, just the share connections sometimes fail & drop out as
does mmc computer management.  Attempts to remap using the machine name
generally fail once this has occurred, using the IP address generally

Here's the global section...

# Global parameters
        workgroup = DOMAINNAME
        server string = My Domain Controller
        interfaces = eth0, lo

Any ideas what's happening here?
