Asked by: firstbenefits

I have a Verizon Wireless card PC5740 that has worked for the past year in my IBM - T60 with win XP Pro.
Last weekend the wireless, Lan, and The Verizon card quit working. I deleted the wireless and Lan from device manager and the computer reinstalled them, and they both work. The verizon gives error 720. The modem was replaced by Verizon after their Tech support failed to correct he problem. I have updated the machine and windows, Bought a registry program and corrected 1900 errors, and the Verizon card still gives error 720.  Can anyone help.

Sounds like something with your network settings went wrong. I would try uninstalling everything in the device manager associated with the Verizon card. If that does not work, click the link below and run that program. I use it to fix network problems usually associated with spyware/viruses, but it may do the trick for you.

I removed the card and it works fine in my other Thinkpad.
I tried the winsock fix, uninstalled IBM Acess connections, deleted all devices, restarted and it still will not connect. I took the machine to a local computerstore and a tech spent an hour and told me all the settings seemed OK. He suggested a reformat of the hard drive.  Is there a way to repair windows XP without reinstalling.

I have been scouring the internet for a solution to this problem but have found none.  Basically, there is a particular variant of the Error 720 problem with IBM Thinkpads.  The problem is located in the PPP protocols/WAN Miniport/ TCP/IP protocols.  I don't know anything, so you guys can tell me whether these are all the same or different parts of the DUN connection process.  

Anyway, it appears as though either the 1) Thinkpad Access Connections Software screws it up or 2) the way the WAN Miniport drivers for OEM Windows XP are installed by IBM is different that with Windows XP.

It seems as though dealing with #1 has helped some, but for others #2 has been isolated as the culprit.  I have searched around and reseting the TCP/IP does not work because it resets to the original, incapable IBM protocol.  The other solution is apparently to do a clean reinstall of Windows XP.  Obviously, I don't want to create another 2 days of work reinstalling everything on my laptop just so I can have broadband access via my verizon phone.  

I hope this helps someone with more expertise than me to find an easier solution.  A lot of people with Thinkpads, Verizon and XP are suffering when it comes to dial up networking.

I have the same problem, has anyone found out how to fix this yet with IBM Think pads. This has to be fixable. I used it on my last computer just fine. This should be no different. I am using a 5750 Verizon Air card  and get the 720 error. Everything is set up propperly and works on my other computers but not the computer I need it to. Help:)

I am experiencing the same issues with the following computers, Lenovo T61, T60 and Lenovo 3000 N100 laptops, I am starting to believe its something  related to IBM drivers as I found the problem always lies in the WAN Miniport IP and PPTP ports only in IBM machines. Here is a list of instructions that work for me for about 15 machines now and I think I got it pretty close. I've read alot on this issue and have done about 6 months of troubleshooting to come up with this solution.

VPN Error 720: No PPP control protocols configured

To resolve this issue, remove the WAN Miniport IP and the WAN Miniport PPTP device, and then reinstall both Miniports.

1.      Delete the VPN connection
2.      Click Start, click Run, type regedit in the Open box, and then click OK.
3.      Locate the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}
4.      On the File menu, click Export& choose a destination and give it a name, and then click Save.
5.      Click each of the registry subkeys under this key, and then view the Data column of the DriverDesc value to determine which of the subkeys corresponds to WAN Miniport (IP). And the one that corresponds with WAN Miniport (PPTP). For example, the 0005 and 0008 subkeys.
6.      Right-click the subkey whose DriverDesc value data is WAN Miniport (IP) (for example, right-click 0005), and then click Delete. Click Yes to confirm that you want to delete the key. Then do the same for the subkey whose DriverDesc value data is WAN Miniport (PPTP).
7.      Close Registry Editor
8.      Right-click My Computer, and then click Properties.
9.      Click the Hardware tab, and then click Device Manager.
10.      On the View menu, click Show hidden devices.
11.      Under Network adapters, right-click WAN Miniport (IP) and then click Uninstall. Click OK to confirm that you want to remove this device. Repeat this step for WAN Miniport (PPTP) as well.
12.      Reboot the PC
13.      Find netrasa.inf in C:\Windows\inf, Open and place a semicolon in front of the line that starts "Excludefromselect=\" and end with "MS_NdisWanNbfIn,MS_NdisWanNbfOut" under the [ControlFlags] section. (all lines between)
14.      Click Start then Control Panel.
15.      Go to Add Hardware.
16.      Click Next, then select Yes I have already connected the hardware, then click Next.
17.      Scroll down and select Add a new Hardware device, click Next.
18.      Select Install the Hardware that I manually select from a list (Advanced), click Next then select Network Adapter in the list and select Next.
19.      Select Microsoft in the left column and then select WAN Miniport (PPTP) and click Next
20.      Select Continue Anyway, Click Finish and close out of everything. Now do the same thing for  WAN Miniport (IP).
21.      Uninstall, then Reinstall network adapters.
22.      Click Start, Run, type in netsh int ip reset resetlog.txt and click ok
23.      Reboot the PC.
24.      Uninstall and reinstall the VPN connection and this should fix the issue.

Some times I have to repeat steps 22 and 23 a 2nd time for it to work. Let me know if this was any help or any other errors that occured after attempting the steps above.
