[Samba] Unable to map or view resources by name

[Jetkins at austinlogistics.com]

Hi, folks.

I'm in the process of setting up a RH ES3 box as a samba server in our 
Active Directory environment.  I have kerberos working for user 
authentication, and can both log into the RH machine and map drives from 
windows clients using domain passwords, but the drive mapping only works 
if I specify the share name with the server's IP address: 
\\10.1.200.114\share1.  If I try using the server's name - 
\\sambasvr\share1 - the authentication fails and I see the following in 
the corresponding client's log file on the server:

[2004/09/22 13:23:15, 1] smbd/sesssetup.c:reply_spnego_kerberos(173)
  Failed to verify incoming ticket!

and the following in the Security log on the AD server:

Event Type:     Failure Audit

Event ID:       676

Authentication Ticket Request Failed:

        Ticket Options: 0x40810010
        Failure Code:   0x6
        Client Address: 10.1.200.26

The system is running kerberos 1.2.7-28 and samba 3.0.6-2.3E.  Any and all 
suggestions gratefully accepted - while it's working as is, I'd prefer to 
get this last wrinkle ironed out before I release it to my users for 
testing.

Thanks,
