IPSEC service won't start



I discovered today that the IPSEC service on my rather new computer
has been failing to start for several weeks, since a few days after I
first set up the computer.

The System event log shows this on each reboot and each attempt to
start the service manually:

================
Type: Error
Event ID: 7023
Description: The IPSEC Services service terminated with the following
error: The attempted operation is not supported for the type of object
referenced.
================

The Services console logs that error and throws this message when I
attempt a manual start:

================
Could not start the IPSEC Services service on Local Computer.
Error 10045: The attempted operation is not supported for the type of
object referenced.
================

Running Windows XP Media Center Edition with SP2 and all latest
critical updates applied. Running McAfee VirusScan and Personal
Firewall Plus.

This problem didn't come to my attention until I tried today to
configure a VPN connection of type L2TP IPSec, which obviously
requires the IPSec service to be operating. The connection is
configured okay, but when I try to connect I get:

================
Error 789: The L2TP connection attempt failed because the security
layer encountered a processing error during initial negotiations with
the remote computer.
================

I presume this is the symptom of the IPSec service not being in a
running state.

I can't find anything relevant in the MSFT KB or Technet.

I posted in this group because it's related to the VPN, but if there's
a more appropriate group, please let me know. Any help much
appreciated.

TIA.
