We have a computer that had a hard drive crash. The drive was restored to a new drive and most everything functions as expected except the PPPoE connection no longer functions and gives a 720 Error. The ethernet card functions, I plugged it into a hub and it DHCP'd and was able to access the internet. I removed and reinstalled ZoneAlarm, and the antivirus. (these had been corrupted in the crash) I have done the MS registry hack to remove the wan miniport IP connection and have repaired IP and Winsock several times. Giving up on the MS PPPoE, I removed the connection and tried a 3rd party (RASPPPoE) with the same results. I am loath to reinstall XP and wondering if any one else has suggestion.
 
Thanks htmlman,

I have been through all the Microsoft technet, knowledge base and msdn articles I can find about both the 720 error and mini port drivers. My suspicion is that somehow there is either a registry corruption or a corruption on a linked file that was corrupted during the crash. The fact that even a 3rd party PPPoE package failed makes me think that something is preventing PPP from finding the ethernet card.

I have removed the card and driver and reinstalled with the same failure. The NIC card works fine when connected to a standard network so it is not the NIC. Looking for someone who has delved into the mysteries of PPPoE and might be able to shed some light. Again I have run the netsh commands to repair/restore the IP stack.
 
I added IPX/SPX early on in the troubleshooting process as an attempt to correct the protocols. Since IP is required by XP now, I could not remove the IP stack but I did use the netsh util to restore it to installation state.
 
I work for a Telco ISP and I get calls from the outside techs when thay have a DSL trouble thay can't get working and I have found the winsockfix.exe program to work when the netsh did not. I have only had on PC Win 2000 Pro that I could not get to work but the pc had been and 98Se that the some kid had load 2000 Pro on and it would not boot to safe mode. So I removed the Speedsteam 5200 witch was modem only and installed a Speedstream 5660 modem router and did not need the PPPoE. You could get a cheep router and us it for the logon, Then you would also have hardware fire wall.
