Hi
I have a user who cannot connect via vpn (home to work connection)error 721. No other users are having any trouble.
Client has XP Pro. SP3 using Windows standard connection. PPTP type.
I have tried adjusting MTU but still no luck.
I can connect from my laptop using her account details using the same type of connection.
I have asked her to contact her ISP to check the modem settings, for Port and Protocol allowance, that was supplied by the ISP.
Windows Server 2003 R2 with Routing & Remote Access setup.

Does anyone have any other troubleshooting ideas? I believe it to be something to do with her laptop. NIC drivers are up to date as is WU.

Thanks in advance

I was having the same issue a few months back, turned out the server was not issuing DHCP from the correct pool. Check this first if you are using the server to assign local IP's as well as VPN's.

Check this site out too, its how I solved it:

thanks for your reply. that seems to be working.
We have several users that connect this way and they aren't having any trouble.
that's why i thought it may be something from her home setup causing the connection problem.

I would check to see if her Windows Firewall is blocking anything. Easy test is to have her shut it off completely and try to connect. If she can, then you can dive deeper into which setting is blocking it. Have her reenable the firewall immediately after the test.

thanks for your help.
her setup is the same as other users, same exceptions.
Users are unable to disable firewall.

Thanks again for your help.
Unfortunately with the computer there was no upgrade to XP and they aren't HP computers. the user is connecting to their ADSL modem at home.
I am still waiting for her to contact her ISP to make sure they aren't blocking ports.
i'll post the outcome of the reply from the ISP when i get it.
thanks again.
