This means that share jCIFS is trying to access was not found. By default
jCIFS tries to connect to IPC$. If you view the domain controller in
Network Neighborhood what happends? Do you see IPC$ listed?

This baddr property is useless as it is '255.255.255.255' by default.
Otherwise the web.xml looks good. If nothing else has changed on your side
I'd guess the domain controller has changed somehow.
