SYMPTOMS

When you use the Add Standard TCP/IP Printer Port Wizard in Microsoft Windows XP or Microsoft Windows 2000, you may receive the following error message:

Error loading the TCP MIB library.

When you click OK, you receive the following additional error message:

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

When you click OK, the Add Standard TCP/IP Printer Port Wizard quits, and no port is added.

CAUSE

This behavior may occur if a third-party version of the Wsnmp32.dll, Ntprint.dll, Tcpmib.dll, Mgmtapi.dll, or Snmpapi.dll file has been copied to the %SystemRoot% folder.

RESOLUTION

To resolve this behavior, rename or delete these files in the %SystemRoot% folder. These files are taking precedence over the Microsoft-supplied file in the %SystemRoot%\System32 folder.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

MORE INFORMATION

The Add Standard TCP/IP Printer Port Wizard checks the root system folder for some dynamic-link libraries (DLLs) before it checks the System32 folder.
