Well, its easily done in unix. You just go into the server permissions and add users. NT accounts in frontpage prompt me for a list thats named after the particular server that my sites hosted on.
When I ask my provider to add names to the list they say they don't support that and I should write an asp security script instead. I now have the asp script, but I think its crappy that they won't do it.
Does anyone know of a web hosting company that will add multiple users and passwords to an nt site?
