I assumed that it was a public access server. That's

But port 139 and 445 are needed if you are using
Filer and Print sharing on that machine.
better idea wud be to filter traffic to this port
or avoid information leakage by changing the
registry settings
restrictanonymos = 2
:-)
We also need to consider wher is it placed in the
network

TCP135, 139 and 445...

For OSScan assuming that port 135 is open and port
