I have VPN setup, it shows veryifying user anme and password, but do not connect

I have VPN setup, it shows veryifying user anme and password, but do not connect.  I have it set to allow dial ins and have given admin priviadges.  It was working fine, is there any reason that would cause it to try to verify the user and pass but either timeout or just not login

We need to know which VPN protocols you are using. The problem and resolution can be very different depending on whether you are using PPTP, L2TP or IPSec.

The endpoint is the device/server that the VPN connection terminates on. Is this a dedicated device (appliance) or is it a server?

Hi bsjld,

This very much depends on the VPN protocols used. Is this a PPTP or IPSec VPN?
Does this happen with all users, or just from 1 location?

Good Luck,

Chris

Please describe your network, What are you using as a VPN endpoint?  What are your VPN clients?  What are you using to allow dial in?  What authentacation method is your VPN using?

Ok,
the clients attemting to log in I have it set to Automatic, and yes, this is a server that handle vpn.  O.S. 2ooo server.  Was workinga feww weeks ago, but had all types of issues lately with the net,  

It must be gettingin because it's attemting to authenticate, but never let me in.

One thing I just tryied.  I attemted to setup a vpn connection from iinside the lan, and atleast I get to the point where it asks me to enter the correct info, usually if this happened I left out the domain, when I enter it it lets me in.

But know when I enter the domain, it still does not let me in.  I di dnot change the domain, could it have changed?

I know the user works, it adminstrator with all rights and has dial in checked.

Did you accept my answer by accident?

If you are using PPTP, you need to allow IP Protocol 47 (GRE) and TCP port 1723 throuch your firewall.
