Firewall applications are designed to block network traffic and secure the desktop PC from incoming network connections. Since ActiveSync utilizes TCP ports for data transfer with Windows Mobile devices, you may need to explicitly allow this traffic to be un-blocked by Firewall applications. To do so, you must add ActiveSync application processes into the Firewall Programs Exception List.
Troubleshooting:
If you are currently running any of the following Firewall Applications, please consult the detailed steps described below to add ActiveSync application processes into the Firewall exception list:
Sygate Personal Firewall
TrendMicro PC-cillin Internet Security 2005
Norton Personal Firewall
Zone Alarm Security Suite
McAfee Personal Firewall
Windows Firewall
For additional firewall software not mentioned, please consult your firewall application documentation on how to add ActiveSync application to the exception list.
Note: ActiveSync files include:
Wcesmgr.exe
Wcescomm.exe
Rapimgr.exe
These application processes are located in the ActiveSync installation folder (C:\Program Files\Microsoft ActiveSync\ if installed in C drive with default settings).
ActiveSync also uses the following ports for communication to/from these processes:
Inbound TCP:
990
999
5678
5721
26675
Outbound UDP:
5679 |
