Maaz,
check that Network Service account had FULL control for System\CurrentControlSet\Services\RemoteAccess\Parameters\Ip key.

P.S. Just in case you didn't see it before: there is a great article "Enabling the ISA Server 2004 VPN Server"
http://www.isaserver.org/articles/2004vpnserver.html
Also, forum on this site http://forums.isaserver.org/ help me a lot with different ISA 2004 issues.

Open "regedit.exe" (registry editor) from command prompt, go to My computer\HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\RemoteAccess\Parameters\Ip,
right click on IP key and select "Permissions". In "Permissions for IP" window check that Network Service account had FULL control.
