One of my ADCs (running oes11 on sles11sp1) has started acting a bit
strange lately.

Our firewall is actively denying netbios packets from this server to a
destination address that I can't figure out where it is.

We run 192.168.x.x addresses here. Our servers are on 192.168.10.x.
This server is trying to send netbios packets to, which is
nowhere on our network, and it can't be a routeable, so I'm not sure
what's going on here.

Also, yast won't launch via the computer button. If I launch it from a
cmd line, it launches, but I cannot configure anything.

An xadcntrl validate shows everything running, top shows nothing really
hogging cpu or memory.
