I have a dynamic VPN set up on a Pix 501 in our office. When I connect from my home computer, it gets in successfully, but if I plug my notebook into the same LAN as my home computer it kicks me out. Our service software is installed on my notebook, so that's what I really need to connect with. The settings in the VPN client are identical. If anybody has any ideas I would be glad to post a copy of our config and the debugs that I have when each of the two computers attempts to log in.
Thanks,

it sounds like the current pix is not accepting remote vpn with pat. try put the command "isakmp nat-traversal 20" into the pix.
if that can't resolve the issue, please post the config.

I already had the nat-traversal set. Like I said, I am able to connect with another computer, set up exactly the same, on the same LAN. After I posted last night, I had a chance to try it through a different internet connection with the same laptop and it was able to connect. When I did this, I tested our tracking software and was unable to connect to it. It is SQL based and tries to find the database with the hostname of the server. I now need to try and find a solution for that as well. *sighs*
Anyway, here is the config. I did crypto ip and crypto is debugs. If you think either of these would help, I will post them as well.

You may have a dns or wins issue. What os is running on the laptop? If it is an ms win version, then do this:
Examine the network connection's DNS Properties on the laptop and see if there is a hardcoded connection specific suffix. If so, does it match what the vpngroup domain name that is configured on the PIX? Also examine how the dns suffixes are appended.
Run the ipconfig /all command and see if you have the proper dns servers listed. See if they match what is configured on the vpngroup.
Let me know what you find.

I have both my notebook and my PC set up to get a DHCP address from my router, so they have the same DNS information. It worked on the PC and not the notebook.
