Re: Remote Desktop access issues

It shouldn't make a difference if there is a program rule and a general
rule -- Symantec Firewall goes through the rulesets (Zone, General,
Program, pRules) and applies the rule for the first match. But when
these is no logged in user, it skips the Program and pRules.

If you want to see where the traffic is being blocked or allowed, turn
on logging for your Remote Desktop rules and examine the logs. When
traffic is blocked because no user is logged in and Program rules aren't
being processed, you will see this in the logs.
