portwindows
I have a program that uses a server's port 1099 but my computer cannot connect (times out). The PC having the trouble is running Windows 7. I have disabled Windows Firewall, the antivirus, and the router has all ports open. Still I cannot connect to the server. I am using telnet 1099 but cannot connect.
Meanwhile, other PCs, on another network can connect with no problem.
Appreciate any tips for troubleshooting.
I've had success with Sysinternals Process Explorer. With this, you can search to find what process(es) have a file open, and you can use it to close the handle(s) if you want. Of course, it is safer to close the whole process. Exercise caution and judgement.
To find a specific file, use the menu option Find->Find Handle or DLL... Type in part of the path to the file. The list of processes will appear below.
If you prefer command line, Sysinternals suite includes command line tool Handle, that lists open handles.
Examples
c:\Program Files\SysinternalsSuite>handle.exe |findstr /i "e:\" (finds all files opened from drive e:\"c:\Program Files\SysinternalsSuite>handle.exe |findstr /i "file-or-path-in-question"

By default a client should not have any problem connecting to a remote server, regardless of the port. From the sound of things it seems more like a Router or Firewall on your network connection may either be blocking on restricting the connection.
I would check your router for any rules or restrictions in place.
