Yesterday a client rang about a slow computer, it had recently had a virus removed from it but still wasn’t working quite right. Closer inspection revealed that a lot of the Windows Services were corrupted and would not start at all, while others were missing completely!
Some of the error messages that you might run into that are symptomatic of this problem include:
- Windows Firewall service (MpsSvc): Error Code 5 or Error Code 0x8007042c.
- Windows Update: Service cannot be started or service is missing from services list.
- Base filtering engine (BFE): couldn’t be started (Error 5: Access is denied).
