I have a few domains that our server can not send a message too. The message I receive is Winsock error 10061 the server has refused to connect with you at the IP. We are receiving messages from them just fine, but we cannot reply. Does anyone have a suggestion?

This error can occur with numerous applications and is often caused by a TCP port being blocked by a router\firewall or a port filter on the NT\W2K Server. TCP traffic is bi-directional, which means the TCP ports have to be opened in both directions.

Blackberry Server Winsock application we use to connect out PIM to our Exchange server. If port 3101, which used by the Blackberry server to communicate, is not open on the Firewall. The server reports a 10061 Winsock error. To verify a port is open or closed TELNET to the port that is used by the application.

For example to connect to an SMTP server type the following:

TELNET 25

25 is the TCP port used by SMTP.
