Troubleshooting network/app connection failure
Posted on 2010-08-31
We have a Windows 2003 Server running an application. The server is at 192.168.1.1 and is named server1.domain.com
The app running on the server needs to speak with another host (server2.domain.com) at 192.168.1.2, however whenever I try to open the app I get the following error: "cannot reach server2.domain.com"
So I ran Wireshark on Server1, filtered for 192.168.1.2, and can see the following:
1. Server1 > Server2 SYN
2. Server2 > Server1 SYN-ACK
3. Server1 > Server2 ACK
4. Server1 > Server2 > PSH-ACK
5. Server2 > Server1 > FIN, ACK
6. Server1 > Server2 > ACK
7. Server 1> Server2 > FIN, ACK
8. Server2 > Server1 > ACK
How can I find out what and who is causing the connection collapse?
