If it is that urgent, I suggest you pay the charge and call Microsoft and Cisco on their telephone numbers which you can find on their web sites.

Glad you think so as I though it quite pertinent to your level or urgency. Providing some basic information would further your cause here though.

Version of ISA and the service pack deployed?
Are you going to establish a VPN to the ASA or the ISA box or is this just remote-access to the ISA server itself for support purposes?
What sort of VPN are you looking to establish? IPsec? pptp?

its ISA2006 and i need to establish an emote access vpn to ISA to connect internal network, and iam looking for IPsec configuration

i canconfigure the remote access for ASA but i think it will not solve the problem and will not allow tto connect the internal network

iam not looking for complete configuration but if i allow the ISA to be a remote access vpn server and tried to connect from internet what type of configuartion i need to allow in ASA to do that

The ASA I can't help you with. I use Cisco PIX not ASA's so the new Cisco;s are no longer my area really.
As fot the ISA Server, you want to pick the back-end firewall template. This will create a route relationship through to the ASA from the internal network making it all much easier for you.

As for the ISA, Microsoft publish a whole raft of papers on the vpn approach and you can find those here. Ther are actually very good and cover pptp, IPsec, roaming users etc.
