But only members of the Administrators or Account Operators group can successfully use some of User, Users, Group and Groups object methods and properties. You can logon to the Administrator account or other account by LogonUser method in ASP page .

      Remember that there are at least three conditions to succefully run LogonUser method :

1. Right UserName, Password and Domain. UserManager raises error when one of them is bad.

UserManager.Server error '8004052e' , Logon failure: unknown user name or bad password.

2. 'Logon locally' (or 'Access this computer from network') right for the user, that is logging on. When the user does not have the right, Usermanager raises this Error :

UserManager.Server error '80040569', Logon failure: the user has not been granted the requested logon type at this computer.

3. 'Act as a part of operating system' for user, in which context is running the process (probably IWAM_... user in isolated ASP process).

Error without the right : UserManager.Server error '80040522' A required privilege is not held by the client.

You can get the context account by the next code:
Dim S

Set S = CreateObject("UserManager.Server")
Wscript.Echo "Current user:" & S.LoggedOnUser

Wscript.Echo "Context:" & S.LoggedOnUser
You must restart computer to apply 'Act as a part of operating system' right if you have Windows 2000.
