Hello DMD6,

Where you able to resolve this issue?  I had the same thing happen and it turned out to be a problem with the shortcut being used to launch QuickBooks.

I had copied a shortcut from another computer to our RDS server and not realized that Windows "helpfully" turned the path into a UNC path back to the computer I had pulled the shortcut from.

Original shortcut Target: C:\Program Files\Intuit\QuickBooks Enterprise Solutions 23.0\QBWEnterpriseContractor.exe

After copy/pasting the shortcut, Windows had changed the Target to:

\\computername\c$\Program Files\Intuit\QuickBooks Enterprise Solutions 23.0\QBWEnterpriseContractor.exe

Launching that shortcut caused QB to give me the same prompt asking for Admin privileges.  After change the shortcut back to the correct local path of C:\Program Files\..... the Admin prompt went away.

I hope this helps.
