EXE permissions

Error message "Windows cannot access the device, path, or file. You may not have the appropriate permissions to access the item". Whenever I try to run a program.

The unit has Trend Micro PC-Cillin 2007 installed, and one of the services was stuck in "starting". Removal and reinstallation of PC-Cillin solved the problem.

If you do get this error message, try disabling your anti-virus/spyware/firewall software first.

No Mixer Device in Windows XP

A client computer came in with no sound. The drivers were installed properly. Trying to load volume control gave an error that there was no mixer devices installed.

Right-click "My Computer" and select "Manage"
Open "Services"
Open "Windows Audio Service"
Change to "Automatic"
Apply changes
Click "Start"

Problem solved!
