We'd been seeing a problem where a cifs testdc would yield the following results:

filer> cifs testdc Using Established configuration Current Mode of NBT is H Mode

Netbios scope "" Registered names... FILER < 0> WINS FILER < 3> WINS FILER <20> WINS DOMAIN < 0> WINS

Testing Primary Domain Controller found 1 addresses trying 192.168.0.10...192.168.0.10 is alive found PDC DC-001

Testing all Domain Controllers found 3 addresses trying 192.168.0.10...192.168.0.10 is alive trying 192.168.0.10...192.168.0.10 is alive trying 192.168.0.13...192.168.0.13 is alive found DC DC-001 at 192.168.0.10 Not able to communicate with DC 192.168.0.10 found DC DC-002 at 192.168.0.13

NetApp was perplexed, had me re-run CIFS setup, etc. to no avail.

Today we rebooted our PDC because we noticed that the master browser registration was in conflict:

NetBIOS Remote Machine Name Table

Name Type Status --------------------------------------------- PDC <00> UNIQUE Registered PDC <20> UNIQUE Registered DOMAIN <00> GROUP Registered DOMAIN <1C> GROUP Registered DOMAIN <1E> GROUP Registered PDC <03> UNIQUE Registered DOMAIN <1D> UNIQUE Conflict ..__MSBROWSE__.<01> GROUP Registered DOMAIN <1B> UNIQUE Registered

After the PDC rebooted, the cifs testdc problem went away.

I know I've corresponded with some folks from toasters who were having this cifs testdc problem. If you're having the problem, can you do an nbtstat -a on your PDC, and see if you see a <1D> entry in conflict?

Thanks, Mad Dog
