I did the "bad thing" of putting in a service pack yesterday - 6a on my NT 4.0
machine.   I then installed some software that was griping that it needed
service pack 6.   The software sucked, so I uninstalled it.   Later I came back
and my PC was frozen.  I rebooted and started getting complaints about
MSVCRT.DLL file.  The Microsoft Knowledge base says I need these files from
another Win NT workstation with Service Pack 6A and Internet Explorer 5.5:

msvcrt.dll
msvcirt.dll
msvcrt20.dll
msvcrt40.dll

(Search knowledge base for "??_U@YAPAXI@Z" for how I found this out.)

 Ugh.  Anyone that can help me?

(Had to even use my Linux box just to get email!!)
