Saving your Password in Dial-Up networking:
If you are using Dial-Up networking and find that the Save Password checkbox is grayed out (so you cannot use this feature), check to make sure that you have "Client for Microsoft Networks" listed when you double-click the Network icon in Control Panel. If it is not listed, select Add, Client, and select "Client for Microsoft Networks". When you restart your system, type in a user name and leave the password box blank (otherwise you will be asked for a password each time you boot up). You should find you can now use the Save Password feature.
