Device manager and security rights

[mundaine]

I'm running a windows xp pro box that's connected to a windows 2000 Active Directory domain. I'm currently logged on as the administrator, and when I try to access Device Manager, I get a message that saids,

"You do not have sufficient security privileges to uninstall devices or to change device properties or device drivers. Please contact your site administrator, or logout and log in again as an administrator and try again."

Then I click the OK button and it opens up the Device Manager screen, but I'm unable to change anything, just browse through it. This problem has hit me a few times before, and I had to remove the computer from the domain, change it's name, and then rejoin the domain (including the several restarts needed to accomplish this).

I don't have this issue with any of the Windows 2000 boxes, only the XP box.

Any help with this would be appreciated as I need to install a new wireless device, and it's not letting me.

ps and no I don't want to go through the domain joining process, I want to know why, being the administrator, am I receiving this message.
