This resolved the problem. Thank you!
If you're anywhere near SF, then I owe you a beer.
Cheers!

I ran into this problem as well and the way I was able to correct it is to set up the timeout property to 500ms
<init-param>
<param-name>jcifs.smb.client.soTimeout</param-name>
<param-value>500</param-value>
</init-param>

Hello Beth,
have you tried to disable "signing" on the Win2k3 R2 server ?
If not, can you try (see screenshot):
- Microsoft network server: Digitally sign communications (always): set
it to Disabled
- Microsoft network server: Digitally sign communications (if client
agrees): set it to Disabled
and restart the server.
bye
