Since you didn't mention of which OS you're running, I'll assume it's either XP or W2K. If either is the case, then I would suggest running Event Viewer (in order to access the error logs, and check for any critical errors)...Start | Run | Type
eventvwr.msc and click OK | Highlight "Application" and "System" independently in the LH pane | Right click the error message(s) (critical errors are in
Red), and select "Properties" | Write down a couple of the error messages related to the 1075 error
exactly as they appear (under the "Description" field), and post them in this thread.
Also, open the System Information tool by typing
msinfo32 in the Run box | Expand "Components" | Highlight "Problem Devices", and look for any problems that might be listed there.
In addition, check to make sure that both the "Print Spooler" and "Remote Procedure Call (RPC) Services are set to "Automatic" under Local Services...Start | Run | Type
services.msc and click OK | Scroll down to each of the Services I made note of, right click and select "Properties" | Check that the "Startup type" is set to "Automatic", then select the "Start" button to start the Service(s).
