JSI Tip 6607. The Add Standard TCP/IP Printer Port Wizard reports 'Error loading the TCP MIB library' and quits?

When using the Add Standard TCP/IP Printer Port Wizard, you receive:

Error loading the TCP MIB library.

When you press OK, you receive:

Specified port cannot be added. Operations could not be completed.

When you press OK, the wizard terminates without adding a port.

This behavior will occur if a 3rd party version of Wsnmp32.dll is located at %SystemRoot%.

To resolve this issue:

1. Use Windows Explorer is select %SystemRoot%\Wsnmp32.dll.

2. Rename the file as Wsnmp32.Old_dll, so that it doesn't take precedence over the Microsoft supplied file at %SystemRoot%\System32\Wsnmp32.dll.
