Failed to connect to a windows service

did it happen to mention which service?

i got the same message.

Failed to connect to a windows service
Windows could not connect to the System Event
Notification Service service. This problem prevents
standard users from logging on to the system.
As an administrative user, you can review the System
Event Log for details about why the service didn't
respond

The computer seem to work fine afterwards. It just says "Please Wait" on the logon screen b4 showing users on the screen for like a minute or two.

Biometric logon does not work, but works on switch user after manually typing in the password for first time.

System Event Notification Service is on Automatic start and running.

Its weird I didnt do anything different. Any solution???

I am running Windows 7 Beta Evaluation copy 7100 and have had this problem appear numerous times. I've been troubleshooting it by simply system restoring although this is getting quite annoying. I have tried to update the winsocks like you would if you were on vista or xp but this fails to fix this issue. When I open system restore I notice this occurs once windows installs "critical updates".
I would love to find a solution for this problem because although the computer runs fine afterwards the start bar is back to the "basic' windows skin and bothers me asthetically as the windows 7 aero themes will not work.
I'm not skilled in computer science or anything either...so I doubt I'll uncover the solution myself. For the time being I guess its back to system restores.
