If you have multiple users on your network domain and want to give a user administrator rights you need to add them to the Admin user group. The process is relatively simple, here is how.
First you need to make sure you're logging in as Administrator or a profile on the domain which has Admin rights. Go to Start \ Run and type in "compmgmt.msc" (without the quotes) and click OK.
This opens the Computer Management screen where you want to expand Local Users and Groups, click on Groups, then double click Administrators on in the right hand side.
In the Administrators Properties window click the Add button.
Since this example is on a domain usually just typing in the users first name and last initial into the object names box … then click on Check Names and the name will be retrieved from the domain and will be underlined. Then just click OK. If you are not able to locate the user most likely they have not been added to Active Directory yet.
