[jcifs] HELP - Weird connection issue ONLY over wireless

Let me preface this issue by saying that this error only occurs when I am
connected to my work network via VPN using a wireless connection at home. 
If I am connected via VPN using an ethernet connection here at home I do NOT
encounter the following  :confused::

1.  Within Eclipse 3.5 SR1 I have a web application that uses jcifs NTLM to
authenticate to our primary domain controller.  NTLM uses the defined DNS.  
2.  When I start up the tomcat 6.0 server and I'm watching the console I
encounter the following error:

ANY HELP or direction would be greatly appreciated. The lead on our team
setup JCIFS within this web application and unfortunately, no one on our
team has any knowledge about JCIFS.  None of us are network people and do
not understand how JCIFS works, so I'll apologize for the lack of knowledge
with regard to this product.  But any assistance, again, would be greatly

I am assuming that there is a setting somewhere on my wireless router that
is preventing me from connecting(?).  Just taking a shot here because if I'm
in the office using VPN over a wireless connection I DO NOT encounter this

Thanks in advance for any help.  Regards.
