APPLIES TO
- Microsoft ASP.NET 1.1, when used with:
- Microsoft Internet Information Services 6.0
SYMPTOMS
Consider the following scenario. You have a Microsoft ASP.NET application that is hosted by using pass-through authentication in a Universal Naming Convention (UNC) virtual directory in Microsoft Internet Information Services (IIS) 6.0. When you try to access this ASP.NET application, you are unsuccessful, and you may receive one or more error messages.
Note By default, pass-through authentication is selected when you create a virtual directory that points to a UNC share. This option is located on the Security Credentials page in the Virtual Directory Creation Wizard. You select this option by selecting the Always use the authenticated user's credentials when validating access to the network directory check box.
CAUSE
This problem occurs because ASP.NET applications are not supported when you select the Always use the authenticated user's credentials when validating access to the network directory check box in IIS 6.0.
RESOLUTION
To resolve this issue, enter a valid user name and password on the Security Credentials page in the Virtual Directory Creation Wizard when you intend to host an ASP.NET application that is located on a UNC share.
