Based on the Microsoft support KBs  this can occur if TCP IP is damaged or is not bound to your dial-up adapter You can try reinstalling or resetting TCP IP as follows    Reset TCP IP to Original Configuration- Using the NetShell utility  type this command  in CommandLine   netsh int ip reset  file name txt    file name txt  is the name of the file where the actions taken by NetShell are record  for example netsh hint ip reset fixtcpip txt  Remove and re-install NIC     Open Controller and select System  Click Hardware tab and select devices  Double-click on Network Adapter and right-click on the NIC  select Uninstall  Restart the computer and the Windows should auto detect the NIC and re-install it  Upgrade the NIC driver     You may download the latest NIC driver and upgrade the driver    Hope it could help

I had the same problem  Most posted solutions would not work  I ran sfc  scannow and it reported that some errors could not be fixed  To address that problem I ran the command  Dism  Online  Cleanup-Image  RestoreHealth  Ironically  I later found the WAN errors had gone away  the 720 VPN error went away and my VPN worked   Hard to believe that the WAN errors were corrected by this rather esoteric command  but it s worth a try

This solved my 720 problem  The idea is to change the driver of the faulty WAN to another network adaptar driver  and then we are able to uninstall the WAN device and then reboot the system    https   forums lenovo com t5 Windows-8-and-8-1 SOLVED-WAN-Miniport-2-yellow-exclamation-mark-in-Device-Manager td-p 1051981

First I would like to thank Rose who was willing to help us  but your answer could solve the problem on a computer  but in others there was what was done could not always connect gets error 720   After much searching and contact the Microsoft support we can solve  In Device Manager  on the View menu  select to show hidden devices   Made it look for a remote Miniport IP or network monitor that is with warning of problems with the driver icon  In its properties in the details tab check the Key property of the driver   Look for this key in Regedit on Local Machine  make a backup of that key and delete it  Restart your windows   Reopen your device manager and select the miniport that had deleted the record  Activate the option to update the driver and look for the option driver on the computer manually and then use the option to locate the driver from the list available on the computer on the next screen uncheck show compatible hardware  Then you must select the Microsoft Vendor and the driver WAN Miniport the type that is changing  IP or IPV6 L2TP Network Monitor   After upgrading restart the computer    I know it s a bit laborious but that was the only way that worked on all computers

Since I can t find a complete or clear answer on this issue  and since it s the second time that I use this post to fix my problems  I post my solution   why 720  720 is the error code for connection attempt fail  because your computer and the remote computer could not agree on PPP control protocol  I don t know exactly why it happens  but I think that is all about registry permission for installers and multiple miniport driver install made by vpn installers that are not properly programmed for win 8 1   Solution    check write permissions on registers  a  download a Process Monitor http   technet microsoft com en-us  sysinternals bb896645 aspx and run it  b  Use registry as target and set the filters to check witch registers aren t writable for netsh   Process Name is  netsh exe   and  result is  ACCESS DENIED    then get a command prompt with admin permissions and type netsh int ipv4 reset reset log  c  for each registry key logged by the process monitor as not accessible  go to registers using regedit anche change these permissions to  complete access   d  run the following command netsh int ipv6 reset reset log and repeat step c  unistall all not-working miniports  a  go to device managers  windows x -  device manager   b  for each not-working miniport  the ones with yellow mark   update driver -  show non-compatible driver -  select another driver  eg  generic broadband adapter   c  unistall these not working devices   d  reboot your computer  e  Repeat steps a  - d  until you will not see any yellow mark on miniports delete your vpn connection and create a new one    that worked for me  2 times  one after my first vpn connection on win 8 1  then when I reinstalled a cisco client and tried to use windows vpn again   references   http   en remontka pro error-720-windows-8-and-8-1-solved   https   forums lenovo com t5 Windows-8-and-8-1 SOLVED-WAN-Miniport-2-yellow-exclamation-mark-in-Device-Manager td-p 1051981
