Eu recebi um erro ao tentar conectar-me ao meu WebService no Windows XP

Question

Quando tento me conectar ao meu WebService, recebo isso:

Server Application Unavailable 
The web application you are attempting to access on this web server is currently unavailable.
Please hit the "Refresh" button in your web browser to retry your request. 

Administrator Note: An error message detailing the cause of this specific request failure can be found in the application event log of the web server.
Please review this log entry to discover what caused this error to occur. 

E o log é:

aspnet_wp.exe could not be launched because the username and/or password supplied
in the processModel section of the config file are invalid.

E isso:

aspnet_wp.exe could not be started. the error code for the failure is
80004005. this error can be caused when the worker process account
has insufficient rights to read the .NET Framework files.
please ensure that the .NET Framework is correctly installed and that the ACLs on the
installation directory allow access to the configured account.

Qual pode ser o problema?

    

Answer 1

Existe a resposta oficial da Microsoft intitulada: CORRECÇÃO: O ASP.NET não funciona com a conta ASPNET predefinida num controlador de domínio que sugere várias soluções alternativas para o seu problema.

Mas gostaria de dar uma olhada em esta resolução terra-a-terra para o erro.
