I just followed Tom's instructions in his article for basic configuration of Netmeeting through ISA using the H.323 Gatekeeper, but with no luck. I'm behind ISA server, and the client is directly connected to the Internet.
The external client can place a call (the caller's name appears in Netmeeting), but no voice/video/chat is available.
I can make a call to the external client, but no voice/video is available, but chat works.
I've tried with and without the Firewall client enabled, and followed Tom's instructions to the letter (checked and double-checked).
Never mind, I've figured it out.
When I made my machine a client of my W2K server, my permissions got mixed/messed up, so some of my programs do not work properly unless I'm logged in as local administrator, instead of logging into the domain as a domain user.
Gave my domain user the proper permissions to access the Netmeeting folder, and it works now.
