I have a watchguard firewall XTM v11.7 with L2TP VPN. I have a bunch of users in groups for connecting. I have one user in a group who when she tries to connect is getting the following error... Error 691 Access was denied because user name or password was invalid on the domain. I've been trying this with my own user name and password and I'm getting the same result. I have been able to connect but I'm getting that error now too. I can't even imagine what the problem is. Except maybe the machine??? or the internet connection from my office? It's a guest network wide open no restrictions. I'm not using LDAP either.
