Some users messages are not recieved

What OS is on the client side, what other applications installed? I wonder maybe this can be some antivirus/firewall stuff.

Clients: Windows XP SP2

Firewall: All clients and servers are inside the firewall - nothing blocked internaly

AV: Running Symantec Endpoint Protection on most stations. A few older ones still running AVG instead.

In all cases, differnt peopel get picked on after rebooting the server. No rhyme or reason to who it is. I believe we may be hitting some kind of threshhold or timeout and the first logged on users (after the most recent reboot) may be getting truncated out.

The plane just flew over my head - Not sure really what this is doing. Its kinda weird however; it might be something antivirus related. I am clueless with this one.

wRoot might be able to help more than I.

Goodluck you two, and if there is anything else that I find with my setup i let you guys know.

thanks.
