Windows skills are a must (Score 2, Insightful)

Since most business still run Windows, you need to find people with enough skills to fix the same problems over and over. Printing, Outlook, and antivirus/antispyware are the base standards. Ask if they know what Active Directory is, and what its used for. The best question, imho, is still to ask what is the quickest way to find out which version of Windows a user is running. (winver.exe ...btw). If they can answer any questions about those, that will filter out most of the riff-raff.
