I've heard about some Port 135 problem and connecting to Microsoft Exchange Server over the Internet. Is it a problem if my ISP blocks Port 135?
Most home ISPs now block Port 135 as a result of the Microsoft Blast Worm in August, 2003. However, we provide free VPN access to get around this issue seamlessly if you are using Windows 2000 or below. If you have Windows XP, then you can use RPC over HTTP instead of VPN.
