Remote Desktop with Virgin BB

Hi,

Any help here would be greatly appriciated as I've tried Virgin customer services a couple of times now and on both occasions (after waiting 10 mins) I'be been told that the ysimply don't know the answer. To cut a long story short I'm trying to connect via Remote Desktop on a Win 98 machine to a Terminal Services Server. I've had the set up working on another machine with a different ISP and everything works fine. For some reason though, the connection won't get through on Virgin. Has anyone had any success with this? I believe port 3389 is required to be open but from what I've seen Virgin aren't meant to block any ports.

Any help would be greatly appreciated.

Thanks in advance,

Ed
