I have even set the email property of the user used to run the AT in Active Directory. Tried, IISReset, even reboot. The STMP Server can send messages, I verified that.

• .NET Development Networking Code, Windows Services

  Hi, I have programmed a small application which can act like both a server and a client. This program can then be used for chatting and file transfers etc. in a peer to peer manner. All incoming traffic goes to port 9001 on each of these applications. Here is my problem. My hardware firewall keeps any messages from getting through. So I have to log on to the router and use port-forwarding so that every message that arrives for prot 9001 is let through. This has two really big draw backs: 1) only a single computer on a LAN can run the program at once, since all the port 9001 traffic is routed to a single computer. 2) the average user will not want to go through the hassle of opening up a port. Infact, it seems like a security risk ...Show All
