Cisco VPN access problem

I need help resolving this. When I connect to my Cisco VPn through a Cisco ASA firewall I get the following error.

Secure VPN connection terminated by Peer.
Reason 433: (Reason Not Specified by Peer)

I need to know what I need to do to resolve this.

Thank you,
Joel

Hi,
Is NAT-T enabled?

If not try enabling it using the following cli,
'isakmp nat-t'

Let me know.

Yes Nat-T is enabled. The problem seems to be with the actual connections gateway because through the same firewall we can get out to the internet.

If ok would you mind just rebooting the firewall?

I can but it will not be until tommorow morning first thing. I will post again if that solved the problem. BTW, what is rebooting hoping to solve?

Actually we figured it out. There is a service account that AD uses to validate authentication throught the ASA. Once we updated the password people were able to connect no problem.

I am having the same problem. I have tried Rajesh's suggestion to no avail.

If there is a service account that AD uses, it would have been extremely helpful if you would have mentioned what it was called. I am unsure if I have one on my server. There is a user called VPN, but no description of what it is or what it's for. Also, I have no idea when or how the 'VPN' user was created. Lastly, where would the user password be set on the ASA so that it matches what I set in AD?
