Hi all. I'm getting 3033 Activesync errors in event logs when users are activesync'ing.  I've googled around and got various articles about setting heartbeats, etc.  I have to say though; this isn't something i've EVER come across before (i.e. I've never had to much about with heartbeat settings before; my installs usually just 'work' :P ).  The error is below.  Do I have to add in heartbeat settings into the registry, or is this gonna be related to the PDA mobile carrier/device itself?  The firewall is an SP1 from Draytek on a fairly-standard Draytek router.

Event Type:      Warning
Event Source:      Server ActiveSync
Event Category:      None
Event ID:      3033
Date:            22/07/2007
Time:            01:34:00
User:            domain\user
Computer:      server
The average of the most recent [200] heartbeat intervals used by clients is less than or equal to [540].  Make sure that your firewall configuration is set to work correctly with Exchange ActiveSync and direct push technology.
