How can I tell who's logged in to my PC?

On trying to shut my PC, I got a message that someone else is logged in. Interesting considering there's only one login. How can I tell who else might ne logged in? And then block them? Or could it just be a gremlin?

OUCH - guessing you know this can be a Really BAD thing....

Are you on a wireless connection by any chance?
Do you have more then one PC and the one in question has a shared printer?

Did you make any type of Remote Desktop Connection to the pc in question?

I am on a wireless connection, but it's encrypted. Only one PC was on. The firewall should block any other access. No remote desktop.

Close your brower(s)

Click START->Run and type: CMD

Then from the cmd prompt type: NETSTAT

Hopefully you won't see any established connections.

Are you running QuickBooks or any other type of software that creates a user account?

There are quite a lot of established connections. Most to localhost but some to an akamai address:
a92-122-209-27.deploy.akamaitechnologies.com:http TIME_WAIT
and a few like 81.52.205.183:http
some more like ww-in-f167.1e100.net:http
and 64.124.194.59.available.above.net:http.

It seems like the 81 ... is also Akamai, the ww- ones are Google and the last one is Abovenet

Should I worry about these? Should I block them in my Firewall?

Did you close your browser so you don't see dozens from web sites ;-)

Ah no I didn't. I shut my browser and Outlook Express and ran Netstat again.

I get four or five with addresses similar to this now: co114ds.col114.mail.services.live.com:http

I did shut the PC down. But I understand now that this was not the first time this message had come up. Could it be something like the Channel4 TV watch again service that's peer2peer?

Run a 'net session' command .. to see if there are other users connected in.

I get "There are no entries on this list" - I presume that means all's well I hope,
