Hi
Thanks very much for your reply. I ran that command and nothing came back so i ran netstat -ano and looked at all of the items in the list and none of them were associated with port 1234
Help! :)

I have a program that listens to port 1234 on my server machine which is windows small business server. This program worked fine up until this morning and I am now getting a socket error 10013 acess denied.
Please can you tell me what could be causing this? Perhaps someone has made some network changes i don't know about. How can i see what sockets are being used on the server and what permissions they have. I don't really know anything about sockets. I've never really had a problem before.
thanks

I'd check the firewall on the server. Either turn the firewall off, or create an exception rule for the program, and test whether or not it is able to start successfully. Something is preventing your program from creating the connection it needs.
If that doesn't help, it's possible one of July's security updates for Windows is at fault, in which case you'd need to uninstall the offending update to get it working again, & contact your program's vendor for help fixing the problem. What program is it?
Also it should go without saying you need to be sure there isn't any malware on the server, and that your security/antivirus software is up to date and running. Something changed, you just need to figure out what.
There is also some sort of network set up which i don't understand which means that I can't access teh windows firewall so i can't use that avenue to investigate either. You get the error
windows firewall cannot run because another compnent is using network address translation
I presume the network has some other sort of firewall protection. I cannot contact the person responsible for setting up the network

It may be that something else is listening on that port. Did you install or patch something else on the server recently?
1. Open a command prompt and do the following:
netstat -ano | findstr 0.0:1234
If you get a result, make a note of the process ID, it's the number on the far right.
2. CTRL-ALT-DEL and open the Task List. Switch to the Processes tab. Add the PID column by selecting View...Select Columns...PID (Process Identifier). Click the column header to sort by PID and find the process number from step 1. Note the name of the program that has port 1234 in use.
