Error 691

Hello, After a working VPN connection i suddenly get the error [quote]Error 691: no acces beacause user or password are not valid at this domain[/quote] I have used different acounts and different paswwords and i am sure i am using the right accounts and passwords, but i keep gettng this error. I also tried to reconfigure RAS, and i got the message that the server where RAS is installed is not mentioned in the security group RAS of the DHCP server. Although when i looked i did see this server in the mentioned group, i removed it and added it again. But still i keep getting this error. What more can i do to check and resolve this error? Thx, Johan Lijffijt The netherlands
