Session Request Failed

[Gill Potter]

I have a Unix server that has been connected to an NT box using smbmount for
quite some time.  All of a sudden I am now getting:

session request to [ip address]  failed
I have rebooted the NT machine assuming that it was at fault, but I still
get the error.  We have not made any changes to this system.  Does anyone
have any suggestions?  I had upgraded the smb clients to 2.0.7 about a month
or so ago, but it worked fine then.
Thanks,

Gill Potter
