Another RunAs Hint–TSAdmin.msc
Posted by Russell Wright on November 29, 2012
Terminal Services Administrator RunAs string in a big company domain with UAC enforced by policy (no GPEdit here). Problem is "the requested operation requires elevation."
Trick is to use the /netonly switch.
C:\Windows\system32>runas /netonly /user:domain\userid "mmc %windir%\system32\tsadmin.msc"
