Can't configure tcp/ip printer port-Error loading the Tcp Mib Libr

I installed Vista RC1 and a network printer via print server. When Vista
installed it saved all of my applications/docs to a folder called
windows.old. I subsequently had to reinstall all of my software applications
to run under Windows Vista. Since I've reinstalled everything I realized my
IP address keeps changing on my printer and takes my installed printer
offline. I corrected the IP address to be static, but now I can't change my
printer configuration in VISTA to correct the Printer Port to be the static
IP of the printer, I receive an message, "Error loading the Tcp Mib Library".
I've searched for this error code all over the place and can't find it
anywhere... anyone see this before?

 

In addition, the print server is a part of the printer.. the Printer is an HP
Officejet 6310 All-in-One with ethernet printer server.

 

Okay... I finally found the solution... I did another search in MSN Live and
located related to Windows XP and Windows 2000... If anyone else has this
problem, the solution is in the Microsoft Knowledge Base Article: 261302...

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.

I found the Snmpapi.dll under the root folder, renamed it (for safety
reasons) and it worked like a dream.... didn't even have to reboot. I was
able to configure my port, correct the IP address and now my printer works
again... Hope this helps anyone else who has this problem.. Have a
wonderful day ... I know I will!
