I have been googleing for 3 days, still couldn't find correct answer yet for this issue. hopeing someone would help me out here.
I have 2 windows2008R2 servers running in the same subnet, actually they are cable connected to each other directly. Both have firewall disabled. Server A can ping Server B successfully, but when i tried to telnet from Server A to a certain port on Server B, it fails. this port is on listening state, and the port local address is 0.0.0.0:1234 (not bind to 127.0.0.1).
The wireshark captured data on Server B says that the TCP [SYN] packet was received by ServerB, and ServerB responced with a TCP [RST,ACK] packet instade of a [SYN, ACK]. which seems exactly same as the port is not listening.
Appreciate for any comments.

are you also telnetting to port 1234? or are you trying to connect to the standard port 23? you should be able to see what port your client is using in the trace.

sounds like the socket is not in LISTEN mode, although you say it is.
