PBM: Authentication requested on .ASP but .HTM pages (IIS 5.1)

[Vince C.]

Hi,

I get an authentication popup when I browse ASP pages only. If I browse HTM
pages I don't need to authenticate. The IIS is installed on an XP machine
and I'm browsing from a W2K Pro machine.

On IIS I allowed Anonymous access. I've also checked the rights on the disk
against IUSR_machine. I get this behaviour with ASP pages even when I grant
full control to everyone on the folder where the ASP are located. I've
rebooted the web server machine (XP) but it doesn't help.

Does anybody have an idea on what's going on?

Thanks in advance,
Vince C.
