I have a VPN server running on Windows 2003 server.
I have 8 client computers (Windows XP & Vista). All clients and server are in LAN.7 clients can connect well with no problem. 1 client (WinXP SP3) hangs at 'Verifying username and password', and then give error 721.
I've tried using different vpn dialer, but to no avail.
I read somewhere from Microsoft website that I need to reset the permission to NetworkAuthority account by running a line of command provided in their web, and I have done that as well.
To date, that 1 client still unable to connect.
All VPN connections are using PPTP. I have created enough ports in the server.
Any suggestion how to fix this problem?
