win 8 VPN

I have setup a icon for VPN in win8 to connect to a 2003 server...

But whatever I use any account to login, it still say 'user name/pwd not matching'

but If I using same info in a Win7,it working fine...

any idea? is it win8 not comptable with win 2003 ?

I select auto or PPTP already and optional encryption or require encryption

still not working in win 8  or win10

any idea?



no one have idea..
