From: Fish in a Barrel on 5 May 2008 12:04 I'm trying to stop a service, if the service exists. Everything works fine if the service is there, but if it does not exist I'm getting inconsistent results. OpenService returns a zero handle, naturally. On some computers (but not all) GetLastError returns ERROR_SUCCESS instead of ERROR_SERVICE_DOES_NOT_EXIST. Why would I be getting this combination of returns?

To determine what the cause might be, it is important to know what "some computers" are. For each one that fails and each one that succeeds, it is important to know OS version Service Pack Installed Hot Fixes installed Does the service exist in the Registry at the time of call even if there is no executable installed? These are a few questions which would have to be answered before any progress could be made. joe On Mon, 5 May 2008 09:04:20 -0700 (PDT), Fish in a Barrel <aaron.m.johnson(a)gmail.com> wrote: >I'm trying to stop a service, if the service exists. > >Everything works fine if the service is there, but if it does not >exist I'm getting inconsistent results.
