(I feel this might be a legit cause...)

Based on the 389(ldap) and 1720(h323hostcall) ports, it seems to me it might be running netmeeting... you might be able to connect and use the remote desktop functionnality...

Port 82 is listed as Xfer utility, so it might help but I've never heard of such a program... Anyone?

What happens when you try to connect with your browser (on port 80 of course)?
Does telneting (to port 80) show anything (don't forget to send 2 returns to a server message)...

BTW, how's that host usually managed?
