Hi Since I installed FR3/SP3 on my server, I can't get the WMI Driver Extensions service to start. I got the following error : "an instance of the service is already running". Since I need this service working for the Client Drive Mapping to work, my users are stuck. Any help appreciated, Laurent PS : I get the following error in the event log : Event Type: Error Event Source: Service Control Manager Event Category: None Event ID: 7001 Date: 10/09/2003 Time: 13:25:18 User: N/A Computer: HERCULE Description (translated): The Network Client service depends on WMI Driver Extensions which could not start : an instance of the service is already running
