The Situation: I have a client who has a dedicated port to the Internet. They have Proxy 2.0 and IIS 4.0 in place for the Interent Access. I am switching them from an Exchange-based (internal) e-mail system to a hosted POP3/SMTP-Outlook solution.
The Problem: I can ping from the workstation by where it finds the IP address of the servers, but the request times out. I have DNS and default gateway settings at the workstations, and ICMP in place. (I am using Windows 2000 at the client PCs.) I am thinking it has something to do with the IPSec in place, however, in review, there are very little restrictions.

Any suggestions would be GREATLY appreciated!

Sometimes you can ping but not make a connection because ping operates on level 3 where a connection requires access to level 4 of the stack. I run into this occasionally and the problem is usually some filtering being done by a router or another device that restricts access but allows an ICMP packet to go through. On some occasions, the communication facility had some problems. When this causes the problem, you ususally drop some packets when doing a ping. In other words, you will not get 100% return on the packets sent. You usually need to let the ping go on for a while instead of only sending 3 or 4 packets.

I hope this helps.

The answer to your problem is at the proxy server. I have the same setup on my net here. At the client you can type ping www.tntonline.com , the proxy server will resolve the address for you but will not let ICMP echo out to the I-net. This should still not impede what you are trying to accomplish though. In the management console you can check and make sure that POP3 and SMTP are setup in the winsocks proxy portion. Also the clients have to have the MSP client installed. I have this on my server so its easier to install but if you dont you can find it on the Proxy Server CD.

Good Luck
