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  folder.



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



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; 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.
