[Samba] network name no longer available

[Bevan C. Bennett]

I have a samba PDC/BDC setup with a small number of W2k clients.
Not too long ago I set up a set of new servers on fresh Fedora 1 boxes 
using Samba 3.0.1 and migrated my LDAP to the new schema. It was all 
working quite well until recently.

Suddenly, when I try to change permissions on a windows share (from the 
windows box), after I give the root password, I get a message that "The 
specified network name is no longer available" and everything fails.

I get the same message when I go into network neighborhood and try to 
browse to either of the SAMBA boxes. Something must have gotten 
glitched, but I'm not quite stumped as to what. I even updated to 
3.0.2rc1 to see if it made a difference...

The one thing that may be relevant is that I had had my primary LDAP 
server hang for a period of time (too many open files, hopefully now 
resolved) which made everyone somewhat upset (oddly, even the BDC which 
is it's own ldap server).

At this point I'd greatly appreciate any suggestions or debugging advice 
that might be offered. I'll try to stick around and offer the benefit of 
my limited knowledge in return.

The other samba system can see everything just fine.

net view on the windows client lists all of the local systems, including 
the samba servers, just fine.

The BDC is currently configured in this fashion, although this hasn't 
really changed:
