[Samba] NT4 PC's will not connect

[brian.anderson at wachovia.com]

We have been using Samba To connect 2 NT4 PC's to our Unix boxes.  These 
Unix
boxes use veritas clustering software for failover.  During our failover 
test
the veritas software unmounted the filesystems and moveed them to another
server.  We are connecting the PC's to the servers using a virtual IP 
address
controlled by veritas.  So when the second box mounted and the application 
on
the PC tried to write out to the file we thought that it would reconnect. 
However, the PC's would not reconnect at all.  Everything in Samba is 
configured
properly and I can swap out those PC's with different ones and everything 
works
correctly. So here is my question.  Is there something like a lock file or 
a
configuration file in NT that will not let these PC's reconnect using 
there net
application? It has to be something PC related, but it is weird that both 
of
these PC's were working great and then we pulled the rug out from under 
them and
they would not reconnect. Any help would be appreciated.
