When I tried to set Physical Path Credentials in the Advanced Settings, I've got an error message as follows:
Internet Information Services (IIS) Manager
Bad Data. (Exception from HRESULT: 0x80090005)
And it prevents me to set specific user to access network shared folder.
Strangely, I have another server with same configuration, it works fine but this one raised the error. Any idea?
I have been having the same issue when I try to add a new vdir that points to a network share location. Frustrating!
I have seen that problem when the encryption keys have been misconfigured, usually because an ApplicationHost.config was copied from a different machine (without importing the encryption keys) or the encryption keys have been override incorrectly.
The reason you get that error is because whenever a password is stored (such as a virtual directory user/pwd) it is stored using encryption and that will cause it to fail.
