If you attempt to start Windows SharePoint Services Search service on MOSS 2007 and receive the following message:
Error “The handle is invalid”
Try modifying the “Log On As” Identity of the service. If it was setup to log on as “Local Service”, chang this to “Local System”, and retry starting the services. This works only when you aretrying to start the service from Services Adminstrative Console.
If you are using the ‘Operations’ tab in Sharepoint 3.0 central administration, start the service with an account which have right previleges. Give the account name as domain\accountname or else the service will not run if you just give the accountname.
