hi to all,
we have an exchange server 2003 at head office. this server is also configured as domain controller and dns server. Exchange server is configured with Global Address List option which allow the clients(Outlook 2003) to download all address in the address book automatically.
Remote site connects to head office using ipsec vpn to head office perimeter router, then it passes through ASA and finally to exchange server(cum DC+DNS).
I have checked by joining the remote site PCs to domain and it works fine which means dns is working also.
But when it select Exchange Server option in Outlook 2003, it is able resolve FQDN of exchange server but following the FINISH button, outlook hangs for a long time (15-20min) and finally it says that it is unable to connect to Exchange server.
