vpn connection
 

my operating system is "suse 9.1" and vpn server on our lan is "windows 2000 server " .i configure PPTP in my computer but see this error :

"MS-CHAP authentication failed: Invalid UserName or Password
sent [LCP TermReq id=0x2 "Failed to authenticate ourselves to peer"]
rcvd [LCP TermAck id=0x2 "Failed to authenticate ourselves to peer"]
Connection terminated."

my UserNAme and Password is correct,please guide me.

helps if you show us the config... if it's saying the username is invalid, i'd really be wanting proof that it's valid...
