Hello.
Im using vista ultimate x64.

When i access the local area connection window where all the TCP/IPv4 and
TCP/IPv6 are. I am unable to click on properties on any of them (yes i am the
administartor)
By other words, i am unable too access the window where you can change the
"Obtain an ip adress automatically" and "obtain dns server address
automatically" options are.

When i sellect TCP/IPv4 or TCP/IPv6, the properties button is just gray. As
is the unnistall button. When i hit the configure button, i just get sendt
back too the desktop. I am also unable to uncheck the TCP/IPv4 or TCP/IPv6
boxes on the left side of the names (or any of the other stuff)

If I hit the install button and try too install i new protocoll, i only get
a error message saying "windows cannot find the file"

Iv'e also tried it using the administrator account. But it didn't help.

What is causing this problem, and how I fix it?

Thanks in advance
