Set up a new IIS5 box, and instead of parsing HTML thru asp.dll like I
usually do on Win2K boxen I used ssinc.dll (since I really only want it to
parse for includes, not ASP code.) No matter what I did, I got an
authentication challenge when I tried to access the page via the browser.
When I changed the parsing to use asp.dll instead of ssinc.dll everything
was hunky dory. All NTFS perms on the file structure are correct, and
IUSR_machinename has log on locally rights, all the usual perms nonsense.

Anyone heard of this? Anyone know how to fix it? Ssinc.dll shows identical
perms to asp.dll.

Thanks.
