Chekpoint VPN and ISA 2004 cant authenticate

[lovalles]

I am connectin to a remote VPN server over my network using the Checkping VPN Client. How ever i login sucessfully and connect to the server. When i try to authenticate the local exchange server i cannot resolve the exchange name server. if i manually enter the server name when i try to access my outlook profile it prompts me for auntentication, and give me wrong username password, using the right user.
If i make the connection without the ISA server everything works fine.
Any suggenstion.
thanks

check the dns first and with auth you use in the isa server, you have an acces rule for the vpn client?

i have created a rule for the VPN client to access all protocols but still the problem.
What should i check in the dns, the VPN client gives me an dNS and all that but where should i exacle check in the ISA SErver?
thanks
