When you run a script to perform a Windows Management Instrumentation (WMI) query for TCP/IP ports on a computer that is running a non-English version of Windows Vista, the query results may be empty. This issue occurs even if TCP/IP ports are installed on the computer. The issue causes the script to be unable to detect the installed TCP/IP ports.

Additionally, you may encounter some function failure. For example, you may be unable to install a printer by using a script that resembles the following script to install a printer:

SELECT * FROM Win32_TCPIPPrinterPort

Note: The issue does not occur on a computer that is running the English version of Windows Vista.
