PPP Error 720 WinXP SP2


Michael Gerbasio

I'm having a really hard time with the error and although I did a search and
found many posts with the same problem, I can't find a solution.

I'm trying to use a dial up network connection with a PC Card (Cingular
HSDPA Option 3g Max) with my IBM X31 Thinkpad. I tried using the standard
DUN setting creating a new connection for the card. I also tried the
communication manager software Cingular and the card manufacturer provides.
No luck, I just get the same error. Cingular couldn't help either. I'm
running WinXP SP2 with all updates applied. I have the latest drivers and
software for the PC Card.

I've spent the last two days reading net postings, tried numerous "netsh int
ip reset" commands, tried the winsockxpfix utility. Removed all my third
party vpn software (nortel and hamachi). My lan and wlan connections work
fine, just this dun connection that is killing me. I have the windows
firewall and the McAfee firewall disabled. TCP/IP is enabled for the
connections as is QoS, File and Pring Sharing and Client for MS networks.
The card dials and connects then gives me Error 720.

Short of reinstalling WinXP (I'm not even sure that would work), does anyone
have a solution or suggestions?
