The frst error you are seeing is caused by the executable required to do image transformations not being in your PATH environment variable.
The second error (bind) is normally caused by something already listening on the requested port or you are running the server as a user that doesn't have root privilieges (as ports under 1024 are protected).
In your case it seems that something is already listening on the port the NetBIOSNameServer is requesting, this is normally UDP 137 & 138 and TCP port 139. Try running netstat -ln to see what is listening to any of these ports.
