I am coding a Windows Service application in VB.NET that needs to map/mount multiple network drives using UNC path in its OnStart procedure so I can access the drives later. Normally I use NET USE to map the network drives to be used in my Win32 application and it works. But when I tried the same technique in my WIndows Service application, the service started but it didn't map the drives I need. I ran the Windows Service under my username and I have privilage to map to the network drives. Is there any security issues that I'm not aware of? Please point me to the right direction. Thank you.
