Yes. Except for Windows 2000 the SMB protocol runs completely over 
NetBIOS and uses the ports udp/137 (NetBIOS name service),
udp/138 (NetBIOS datagram service) and tcp/139 (NetBIOS session service).
Windows 2000 can additionally run SMB over tcp/445 

However you can also do MS-RPC calls over the NetBIOS interface...

Should be no Problem I think ?
