I have an application server, Server1, running on Windows 2008 Server. I have clients from many subnets connecting to it, some are on the same LAN, some are connecting across the WAN.

We often have connectivity issues so I was looking for a program/function that told me whether the server had actually recvd the connection from the client and what state it was in. I figured on Netstat but then came across TCPView.

I had some questions I was hoping someone could assist me with:

1. If I had a connection from a client at, is there a way to actually filter for this, or do I need to sort by IP address (Remote Address).

2. If I had a suspect connection from and wanted to close this, what's the best way to do this?

3. I see there are connection states of:



Does anyone have a handy link to explain what these mean?

1) TCPView has no filtering capabilities.

2) That I am aware of Windows does not have a way to terminate a specific active TCP connection.  I'm not sure, but I don't think *nix does either.

3) Although for the NETSTAT command it the same states: http://support.microsoft.com/kb/137984

You may want to look into Wireshark (http://www.wireshark.org).  This allows you to capture traffic and see what they are doing.  This allows you to filter on specific IP address (and TCP or UDP ports along with a lot of other filtering capabilities).
