| Event Information | According to Microsoft: Cause: No connection could be made because the target computer actively refused it. This usually results from trying to connect to a service that is inactive on the foreign host. You might have gone to the wrong host, or the server application you are trying to contact might not be running. In TCP, an attempt to connect (TCP SYN packet) caused the destination host to respond by returning a reset (TCP RST packet). If an application sends a UDP packet to a host that has no socket listening, the host may send by a ICMP Port Unreachable packet. Resolution: Check the destination address you are using. If you used a hostname, verify that it was resolved to the correct address. If your hostname resolution uses a local host table, it is possible the name was resolved to an obsolete address. It is also possible that the local services file has an incorrect port number (although this is unlikely). You can run netstat -a at the command line to check port configuration. You can verify that the remote computer is rejecting your connection attempt by checking the network statistics locally and to verify that you are receiving TCP resets or ICMP Port Unreachable packets each time you attempt to connect. |
