Upon login to the Geo Web Publisher Administrator, users may encounter the following error:
Administrator login error: 500.24 - Internal Server Error
An ASP.NET setting has been detected that does not apply in Integrated managed pipeline mode.
This can be caused by an unexpected .NET version, or more likely by errant setting of the GWP Webservice AppPool within Internet Information Server.
Examine the application pool via IIS manager, and modify the Managed Pipeline mode to be 'Classic' if 'Integrated' is the existing selection.
To modify the pipeline mode, select 'Advanced Settings' for the application pool from the context menu.
