Error opening site collection when using -UserName and -Password params

Nov 16, 2011 at 10:49 AM

When I launch the SPWakeUp from the Farm (Installation) account everything works fine.

However when i try to launch the application from the Admin account and use the -Username and -Password params I get the "Error opening site collection" errors on all sites.

Including the -Domain param did not solve this issue. Please tell me, what am I doing wrong?
