How could the DSL provider block ports within the PPTP tunnel? Does he run a personal firewall? I have a user with a personal firewall that keeps blocking 135, preventing him from connecting to the Exchange server. He opens the port up and it works until the firewall decides to block it again. He is connecting over a VPN with XP Pro(built-in personal fw), but ME with a personal firewall could possibly exhibit this behavior. BTW, he also can browse the network and the problem seems to be connecting to Exchange via Outlook 2000.

It was actually pretty painless, but it did require a reboot after modifying the registry. Q155831 Q148732 If you can find out what provider is being used at the far end, you might be able to contact their support and find out what ports they allow through and set you server accordingly.
