Access Active Directory Users & Computers (ADUC) Snap-in from different domain (no trust)

Just a quick steps to access ADUC MMC from Domain A to Domain B where as no explicit and cross forest trust has been setup.


  • At least an Domain user account from Domain B
  • Network ports LDAP 389 should be opened for Domain B domain controller
  • ADUC tools must be installed at source


From a CMD (as admin) run:

runas /\Username /netonly “mmc %windir%\system32\dsa.msc /server=domainB domain controller”

(will prompt for password) : submit the domainB user password

Here will open the ADUC console, feel free to comment and suggestions.
