hi, I have Vista build 5259. I have an administrator rights but when i want to change settings of LAN adaptor ( i need to change my IP address and DNS because my network doesnt support automatical mapping). But when I open this settings Vista warns me that I DON'T have enough rights for changing this settings..... WHY??? What can I do with it? I tried booting in Safe-mode with networking but when I try to open network properties Windows Explorer always stops working... Thank you all in advance.
