I have been seeing the following warning message in application log of my exchange server 2003.
Event Type: Warning
Event Source: Server ActiveSync
Event Category: None
Event ID: 3033
Time: 8:48:32 AM
Computer: Server Name
The average of the most recent  heartbeat intervals used by clients is less than or equal to . Make sure that your firewall configuration is set to work correctly with Exchange ActiveSync and direct push technology. Specifically, make sure that your firewall is configured so that requests to Exchange ActiveSync do not expire before they have the opportunity to be processed. For more information about how to configure firewall settings when using Exchange ActiveSync, see Microsoft Knowledge Base article 905013, "Enterprise Firewall Configuration for Exchange ActiveSync Direct Push Technology"
Just wanted to know where in settings of PIX506e firewall needs to be changed.
what is your setup ? what exactly is said in article 905013 ? What do you want to accomplish here ?
article 905013 doesn't say what changes need to be made to pix506e, but it asks to increase the http/https time-outs in your firewall.
Our PIX506E is opened for port 25/http/https for the mail server.
You can change the following timeouts on PIX:
timeout [xlate hh[:mm[:ss]]] [conn hh[:mm[:ss]]] [half-closed hh[:mm[:ss]]] [udp hh[:mm[:ss]]] [rpc hh[:mm[:ss]]] [h225 hh[:mm[:ss]]] [h323 hh[:mm[:ss]]] [mgcp hh[:mm[:ss]]] [sip hh[:mm[:ss]]] [sip_media hh[:mm[:ss]]][uauth hh[:mm[:ss]] [absolute | inactivity]]
You might be looking at the timeout conn (connection timeout), but make sure it affects all connections !! just not http and https .. i'll anyway go through the article and see..
can you give me the instructions or a link that would show where this is done thru PDM.
I have a TAC case open for this currently. Once I have additional data I'll post what I can.
