I'm trying to get a video conference working between a W2k
Professional system and an XP system.
The problem is that the remote system (XP) can recieve my video, but I
can't receive his.
My machine (W2k) is behind a router with a firewall, BUT I've enabled
DMZ for my IP address so all firewall filtering is bypassed.

Interestingly we had the same problem before I installed the router.
I'm wondering if the XP version of messenger is compatible with the
W2k version?
Both machines are running messenger 6.1
 
Anyone else had any sucess with this particular setup?

Thanks.
Andrew.
