[IMail Forum] [OT] Any way to install IIS4 over NT with SP4??

[Ron]

When I try to install the NT Option Pack over SP4, I get the warning
"hasn't been tested with SP4, blah blah blah", but let's me proceed. It
then fails on an "indexsrv.dll" file.

I *really* need to get IISv4 going on this webserver, but am getting
dangerously close to attempting a clean NT install. I cannot
successfully remove SP4 and get back to SP3, and I can't install SP3
over SP4.

Anyone?

TIA,
Ron
