error code 721 ( ppp & dun related)

by shortstuff . Updated 18 years, 6 months ago

Hi guys, I recently built a new system for a friend that worked fine while conected to my lan. No probs with internet connection etc. However, after he’s installed his own ISP’s usb adsl modem and setup he finds he cant connect to the ISP/internet.
Instead he gets a error 721 ( which I believe relates to a PPP error.) The strange thing is if i connect his old machine it can use the modem etc without problems.
So far I’ve checked the settings, fushed the registry key using netsh etc reinstalled the modem drivers and created a new dun setup.
Now I’ve come to a loss .. and I cant find any other help topics on google etc
Unfortunately the ISP isnt any help what so ever.
Is there a way to transfer the old DUN settings etc to the new PC?
He’s running XP pro on both machines, SP2, all the latest updates, the new system having a 2600 dual core processor and 1 Gb of memory installed
any help would be appreciated,
many thanks
glenn
