The customer is likely using broadcast resolution based on the messages.

What is the filer's name and IP address? It would seem that they duplicate the domain controller. A cifs testdc should help debug the naming and dc resolution.

cifs testdc [ WINSsvrIPaddress ] domainname [ filername ] is used when the CIFS subsystem is not running. WINSsvrIPaddress is optionally given to have the Filer use WINS name resolution to locate domainname; otherwise, the Filer will use broadcast name resolution to attempt to find domain controllers. WINSsvrIPaddress is the IP address of a WINS server in the domain. filername is the name of the Filer in the domain. If the name of the Filer is not given, then the Filer will manufacture a name to use for the search. purple> cifs testdc 10.10.10.55 nt-domain Test will use WINS name resolution Testing WINS address...10.10.10.55 is alive Using name NTAP1783328093 Testing name registration... succeeded Current Mode of NBT is H Mode

It would probably also be useful to get the output of the rc_toggle_basic command nbtstat

You might want to browse your WINS database for DC records with the name "EZE". It looks like you might have duplicate entries for it which can be corrected by deleting one. Darn WINS. =)

Has anyone else seen this problem. Users have no problem getting to the filer. Configurations on DC seem to be correct.
