TCP/IP Properties disabled

[Jack]

Hi,

Using windows 2000 professional, I changed the TCP/IP
settings (from automated to specified DNS).
Now I can't turn it back.
My internet connection now can dial the providers phone,
I get autentificated (username and password ok) but then
I get an error by the network identification (error 720:
could not agree on PPP parameters).
Do you know how to access these TCP/IP parameters? When I
mark the TCP/IP from the list on the "networking" tab,
the properties button is always disabled.
I tried to delete all int.connections and make new ones,
I always get this error.
Thanks, Jack.

If the properties ius disbale you do not have sufficent
privlages to change that. You need to login as
administrator. Or contact your local administartor and
have him/her change them for you.
