Hi. Background: WSS 3.0, IE 8.0 , Vista. Problem: User tries to click on a Datasheet view. IE shuts down. This user seems to be the only one experiensing the problem. Event log has a set of Errors, referring to several services: "Disabled performance counter data collection from the "WSSMatrixpi" service because the performance counter library for that service has generated one or more errors. The errors that forced this action have been written to the application event log. Correct the errors before enabling the performance counters for this service." "Disabled performance counter data collection from the "WSSIndex" service because the performance counter library for that service has generated one or more errors. The errors that forced this action have been written to the application event log. Correct the errors before enabling the performance counters for this service." Tried: Running lodctr /r Enabling and deleting Disabled performance counter keys in the regitry (they reappear) Any idea? Thanks!
