Source Insight Cannot See Network Drives

Symptom: Source Insight cannot see network drives that are mapped to drive letters.

This caused by a feature in Windows the blocks mapped drives in processes running with elevated privileges when the drives are mapped from a lesser privilege process.

If you are running Source Insight from an "elevated" command prompt (for example an Administrator command prompt), or you always run Source Insight as Administrator, but you are mapping the drives in Windows Explorer, then Source Insight may not be able to see the mapped drives. This is a security feature of Windows: If you map a drive using Windows Explorer, an elevated Command Prompt (or any other elevated process) will not be able to see it.
