Fax service not starting

Hi

my PC is windows XP SP2.

I have a problem with the fax service - it doesn't start properly.

The status of the service in service control manager is "Stopping" and the
fax printer is inaccessible when opening the fax console.

The last change to my PC was applying SP2. The faxfix registry entries
relating to rpc are already in the registry.

Reinstalling the fax components works only until the next reboot.

One workround is to kill process fxssvc.exe then start the service manually,
then it works normally.

I can't find any resources on this matter. Is the fax service trying to
start before an essential service? Current dependencies are Plug and Play,
Print Spooler, RPC and Telephony.

Please help.

Regards

Scott
