Yep, not even sure if thats the proper terminology. First time exposed to it.

I have 3 pc's ive begun setting up with an application which affords this as one of its features. Ive allowed Distributed Tracking Coordinator through the firewall on my private network for all 3 pc's, however only 1 can actually send messages to the other 2.

On the 2 problem-pc's I can see the csrss.exe window flicker in the taskbar and quickly disappear, but nothing is ever sent.

No idea where to begin figuring this out. Hoping a bored systems administrator can see the potential issue ez-pz and point me in the right direction ;p
