Communication:  Dial-up Network

Save Dial-Up password

If you can't save your dial up password because it's grayed out, then navigate to HKEY_LOCAL-MACHINE\ Software\Microsoft\ Windows\CurrentVersion\ Policies\Network].

DisablePwdCaching must be set to 0 (rather than 1).

I do not have Network in my Windows XP registry.
