Because your computer is on a domain, you can create local user accounts, which give people access to your computer but don't give them access to the domain. Only system administrators can create domain user accounts.
Open Microsoft Management Console by clicking the Start button , typing mmc into the search box, and then pressing Enter. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
In the left pane of Microsoft Management Console, click Local Users and Groups.
If you don't see Local Users and Groups, it's probably because that snap-in hasn't been added to Microsoft Management Console. Follow these steps to install it:
In Microsoft Management Console, click the File menu, and then click Add/Remove Snap-in.
Click Local Users and Groups, and then click Add.
Click Local computer, click Finish, and then click OK.
Click the Users folder.
Click Action, and then click New User.
Type the appropriate information in the dialog box, and then click Create.
When you are finished creating user accounts, click Close.
