winlogon.exe - unable to locate DLL

[epout]

Can someone pls explain to me how i can fix this error -

I have Windows NT originally in my machine, then I upgrade to Windows 2000 prof. After finished upgrade, I receive the following message

Winlogon.exe - Unable to locate DLL
The dynamic link library TXFAUX.DLL could not be found in the specified path.
c:\winnt\system32, c:\winnt\system, c:\winnt\system32\wbem,
There is more to this message, basically the paths of WINNT and SYSTEM32

Here are the steps I took

I tried SFC /SCANNOW and reboot the system and the error message still come up.

I ran "regsvr32 txfaux.dll" and received this message
loadLibrary "txfaux.dll" failed - the specified module could not be found

Get it working by copying

c:\winnt\servicePackFile\i386\txfaux.dll to c:\winnt\system32

sfc /scannow won't fix it. An update has caused the problem and this is the only way I have found to fix it.
