[jcifs] The network name cannot be found error

[Pitre, Russell]

Hello All-

We are using the jcifs filter for our intranet authentication.  It's
been working great, but all of sudden this afternoon we started seeing
the error you see below.  Nothing has change with the intranet code.  We
are using 2000 Active Directory and Tomcat 5.0.24.  I'm pretty sure the
error is coming the Domain Controller but I'm not entirely sure what to
look for.  I went through the event logs but have not found anything
that stands out.  Any ideas?

ERROR:

jcifs.smb.SmbException: The network name cannot be found.
