Hi Danny

Thanks for the info. However, I  have pix fw  and my dns server & exchange
server are ruuning on AD domain controllers and my DNS zone file is hosted
with ISP dns server and I am using PPTP & L2TP on w2k server. I am using

Remote users are using xp vpn client to connect ... having no problem with
exchange server. But if you use Cisco VPN client & and cisco vpn network
appliences then probably there could be some configuration issue that
require you to put static mapping for dns.
