To designate a primary computer in Active DirectoryDomain Services (AD DS), use the following
procedure:
1. Open Active Directory Administrative Center.
2. In the console tree, under the domain name node (dPMDemo in my case), click Computers.
3. To designate PMClient1 as Bob Smiths primary computer, double click PMClient1, and then in the
Extensionssection, click the Attribute Editortab.
4. Double-click the distinguishedNameattribute, right-click the value and then click Copy.
5. In Active Directory Administrative Center, click Users, and then double-click Bob Smith. In the
Extensionssection, click the Attribute Editortab.
6. Double-click the msDS-Primary Computerattribute, paste the distinguished name of PMClient1 into the
Value to Addbox, and then click Add.
You can specify a list of computer names in the Value to Addbox; each listed computer will be designated
as a primary computer for the user.
7. Click OK in the Multi-valued String Editordialog and again in the Bob Smithwindow.PMClient1 is now
configured in AD DS as a primary computer for Bob Smith.
