Hi All, I receive the above error when I attempt to use the FileSystemObject to write to a text file on the server. My searches indicate that the cause may be that the proper permissions are not set for the root folder. When I use IIS7 manager to try to set Anonymous Authentication to Specific User, I get this error: Keyset does not exist (Exception from HRESULT: 0x80090016). I'm entering my own user name and password in Set Credentials. Does anyone know what I'm doing wrong, and how to fix it? Thanks in advance for your help.
