When I want to enter the Windows user's password, IIS tells me that the password is invalid.
However, I am administrator of my machine, and I launched "IIS" in administrator mode.
There must be a trick somewhere ?
Thank you very much for your help !

A common cause of this error is not adding the domain name to the login (DOMAINNAME\username). It defaults to a local account.
Or you can do this from the command line using appcmd.exe.
This method is described in the article:
