OK - I'm a bit techie, and am the sort of person who actually looks through the system logs on their computer. When I started getting the above message as an error in my system log with an event ID of 7000 I was a bit concerned - I don't like errors. This one was occurring more than once on a regular basis.
After some searching I found references on the web to this error - the problem is that the service to which it refers does not appear anywhere obvious. I had to resort to the registry (don't do this if you don't know what you are doing - messing with the registry is an instantaneous way of screwing up your computer big time).
I found a reference to the solution given by Shain Wray of Microsoft PSS Security Team. It is as follows:
1. Start the registry editor and find the following
2. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
3. Look for an entry listed as DgiVecp
4. If you find this, then change the Start data value to 4.
5. Reboot the system and see if the message is gone.
This worked for me, so I thought that I would share it. Thanks Shain.
