I can't setup the IP for network connection.

Well,

from some time now, when I log in to may computer (Vista B2) I have all my
networking running fine as long as I have DHCP services. I use domain user
account, witch is added to local Administrators group. Well I can change all
setting in network center, but when I want to personalize the connection
itself (remove or add protocols, change IPv4 address) I got the dialog box,
but it's empty and the cursor changes to busy while it's over it. After a
while I title with "Not responding" and all I can do is to Close a dialog
box.


When I log in as an Administrator nothing like that happens. I can easily
which network settings.

Any ideas?

Best regards,
Christopher
