unable to access network properties

Pc is running Windows 98.
I have no problems with dialup networking and am using
ADSL with external ADSL modem - connect to Internet fine.

My problem is I am unable to access the Network properties
from Control Panel or Properties menu from Network desktop
icon.

I applied DUN 1.4 but didn't solve problem.
I want to change the DNS settings. How can I do this ?

Also, can someone offer info on where dialup network
settings are stored in Windows 98? registry ? location ?
