Issues about
using firewall
applications.
• 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 powered
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. Please consult
your firewall application documentation on how to add
ActiveSync application to the exception list.
• 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, 5679, 5721, 26675
– Outbound TCP: 5679
I upgraded to
Windows Media
Player 10 and
now it won’t
synchronize with
ActiveSync.
If you upgrade Windows Media Player application
version 10 after you have installed ActiveSync on your
desktop PC, you must perform a repair installation of
ActiveSync.
I upgraded my
PC operating
system or
installed a Service
Pack and now
ActiveSync won’t
synchronize.
If the desktop PC operating system is upgraded, or a
Service Pack is installed, you must perform a repair
installation of ActiveSync.
