The Web Client may not load if the account running the ASP.NET worker process is locked. This account is typically named ASPNET. When the ASPNET user is locked, the following errors are displayed in the Windows Event Viewer:
-
aspnet_wp.exe could not be started. The error code for this failure is 800700CB. 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.
-
aspnet_wp.exe could not be launched because the user name and/or password supplied in the processModel section of the .config file are invalid.
Users attempting to log on to the Web Client may be presented with the message, Server Application Unavailable.
