Snap server in Samba PDC domain

[Martin Austin]

I've trawled the Archives for assistance with this problem, but all the 
threads I've found petter out without a solution being posted.

We have a Samba 2.2.1a server as a PDC for our network of NT4 and 98 
machines. They all get along fine. We have roaming profiles established so 
people can move around. All no problem. We have a Quantum Snap 2000 server 
that has all our working directories, which until this week was in a 
separate workgroup (as the 98 machines accepted both, and the NT machines 
seemed to be able to tolerate it).

About a week ago the NT machines stopped being able to see the workgroup 
that the Snap server was in, so we migrated it to the domain. Now everyone 
is happy, except the one NT machine that performs our backups of the Snap. 
It can see the Snap through Network Neighborhood, but after a while (I 
guess a few hours but I'm at a loss as to how to prove this) it 'loses' the 
ability to actually access the folders that the Snap exports. Clicking on a 
folder in Explorer gives a 'File or folder moved or deleted' dialog.

I can't find any errors reported in the Samba logs. The Snap only gives a 
warning when trying to access user/groups from the Samba PDC ('Failed to 
connect to IPC$ on domain controller').

If I log out and log back in the folders become visible again (but I'm not 
dedicated enough to be around in the middle of the night when the backup 
kicks off).

Our Samba server is our WINS server. We have a separate DNS server. We have 
encrypted passwords enabled. We don't do DHCP. The Snap OS is 3.1.x. The 
Snap reports to be a Lanman 3.1 server clicking on the 'Properties' under 
Network Neighborhood.

Has anyone any suggestions? Is there a TTL in Samba that needs to be 
increased, and if so, how? Has anyone else ever integrated a Snap into a 
Samba controlled network?
