Portqry.exe is a command-line utility that you can use to help troubleshoot TCP/IP connectivity issues. Portqry.exe runs on Windows 2000-based computers, on Windows XP-based computers, and on Windows Server 2003-based computers. The utility reports the port status of TCP and UDP ports on a computer that you select.
Note Version 2 of Portqry.exe is now available. The Microsoft Download Center link at the end of this article has been updated to reflect the new version. Version 1.0 of Portqry.exe has been removed from the Microsoft Download Center.
Portqry.exe reports the status of a TCP/IP port in one of the following three ways:
ExamplesThe following command tries to resolve "reskit.com" to an IP address and then queries TCP port 25 on the corresponding host:
portqry -n reskit.com -p tcp -e 25The following command tries to resolve "169.254.0.11" to a host name and then queries TCP ports 143,110, and 25 (in that order) on the host that you selected. This command also creates a log file (Portqry.log) that contains a log of the command that you ran and its output.
portqry -n 169.254.0.11 -p tcp -o 143,110,25 -l portqry.logThe following command tries to resolve my_server to an IP address and then queries the specified range of UDP ports (135-139) in sequential order on the corresponding host. This command also creates a log file (my_server.txt) that contains a log of the command that you ran and its output.
portqry -n my_server -p udp -r 135:139 -l my_server.txtPortqry.exe is available for download from the Microsoft Download Center. To download Portqry.exe, visit the following Microsoft Web site:
