Two administrators - different priviledges?

[jollyinsd]

I have two user accounts setup as administrators on my computer, but they act differently. Both accounts have UAC enabled. In one account, I receive error messages when performing different action, such trying to add a printer or access another computer on the network. The error message says that "the operation has been canceled due to restrictions placed on this computer. Please contact your administrator." I found that I can actually install the printer if I right-click in the printer window and select Add Printer from the "run as administrator" section. However, this account is an administrator, so that's a little confusing.

Ok, whatever, Vista is protection happy, I get it. Now for the weird thing, the second account can Add a Printer from the same window without having to go to the "Run as Administrator" part of the right-click menu. What's going on here, and how do I give the first account the same access settings? Like I said, both accounts have UAC enabled, and both accounts are in the Administrator group (and only in that group). They're both the same as far as I can tell.
