Site to Site VPN Event ID 1054 Windows cannot obtain a domain controller

I am trying to run AD computer group policys but I am getting this error on all XP PRO pcs at this site. It is a site to site vpn connection (Pix501 -Pix515E) I can remote manage these pcs, ping the domain controllers. I have tried a couple recommended fixes by Microsoft, one being the registry value GPNetworkTimeoutPolicyValue, but that didnt work either. Domain Controllers are W2K Hopefully someone can help direct me here. Thank you.

Try this:

Adjust the MTU size for VPN tunnel interfaces on PIX

Use the command ?sysopt connection tcpmss (bytes) ?

Force TCP proxy connection to have a maximum segment size no greater than bytes. The

default value for bytes is 1380.
