microsoft-ds: mystery user with screen grab!

I use TaskInfo on my Win2003 Server to monitor resource usage. There is an IP that has shown up with a connection a few times...when there shouldn't have been any real traffic on the server.

Take a look at the screen grab and let me know what you think. I've googled microsoft-ds and can't come up with anything definitive yet.

Can anyone tell me what microsoft-ds is and what this person would be doing accessing the service/port. Traffic seems normal while the person is accessing...no bandwidth spikes.

Help me figure this out.
