W2K network issue

[Christopher Biessener]

I am running Ubuntu 8.04 with auto updates on.  The morning of 12-04-08 
I could see and use the shares and printers on my W2K network.  The 
afternoon of 12-04-08 I could no longer even see the W2K server.  I have 
tried to reinstall samba as well as smb2www and smbc as alternate 
viewers to nautilus.  Nothing works.  Please help.

Thanks,

Christopher Biessener
