I have a website in IIS ... the home page appears as expected. However, when I login I get a permissions error on the above mentioned subdirectory. When I navigate to said folder and attempt to grant permissions to the application pool I notice that none of the C:\Windows subdirectories allow adding a new user to the subdirectory ... the Add button is grayed out in the permissions dialog. So, how to I grant permissions on one of the Windows subdirectories! I've spent the whole day Googling this problem to no avail.
What I have tried:
Everything I know to ... mainly right clicking on the subdirectory name, selecting Edit from the inetsrv Properties dialog, selecting Edit but cannot add a Group or User Name since the Add button is grayed out.
