Activesync problems after installing windows firewall

Posted on 2009-05-01

After a recent virus scare we decided to enable windows firewall via a GPO, this is fine for the most part, but since then our directors PDA has not synced with ActiveSync 4.1.

I have added the port exceptions as instructed by microsoft, as follows:

.....and program excpetions as follows:
C:\Program Files\Microsoft ActiveSync\CEAPPNGR.exe:*:enabled:ActiveSync
C:\Program Files\Microsoft ActiveSync\rapimgr.exe:*:enabled:ActiveSync
C:\Program Files\Microsoft ActiveSync\wcescomm.exe:*:enabled:ActiveSync
C:\Program Files\Microsoft ActiveSync\WCESMgr.exe:*:enabled:ActiveSync

Yet it is still not working and the heat is begining to build. I have attached a copy of the Pfirewall.log from the user computer.

Any ideas would be very greatfully received.

    Disable Windows firewall.  I promise you that it is giong to cause a LOT more headaches than it will possibly resolve.

    For the virus problem, get good anti-virus & anti-malware software packages and maintain it / them properly.

    Make sure the don't allow exceptions is not checked. Also Activesync should add the correct exceptions on it's own. Try reinstalling or upgrading to the current version 4.5 (if compatible).

    I suggest that you have a look here and check what IPs have been allowed to use the ActiveSync.

    Hope it helps.

    Clarification for future generations reading this thread ;-)

    Windows Firewall has it's place, and can be indispensable in some environments.  For example, anybody connecting to the Internet using dial-up, public hot-spot, or any other technology that puts a computer onto a shared, non-trusted network should have a firewall running.  Not so much to protect against viruses or malware (best defense against these is software specifically designed for the task) -- but to protect against other people who my want to hack into a system for various reasons.

    In other environments, however, the firewall adds no value and creates support headaches.  An example of this would be in a corporate network.  A proper business network already has edge firewalls, already has other network and system security measures in place, and should be restricted to use by "trusted" users.  So turning on the Windows firewall is just going to mess with things and make support more difficult.
