Test Server - Win 2003 SP1 Clean Install
Need to turn on Subauthentication for webapps connecting to Win2k SP4 Dom

>From IIS6 help to turn on step 1 = command prompt
rundll32 c:\windows\system32\iisuba.dll,RegisterIISUBA

I get "Error loading c:\windows\system32\iisuba.dll"
"The specified module could not be found."

Windows Search won't locate the file either.
If I use Win Explorer to browse to that location...there it is plain as day.

I'm Stuck. Any ideas?
