When attempting to open a Transaction or Query script from Winshuttle Central you receive the error that the "TxR could not be downloaded or it does not exist on the server". In addition, if you use Transaction to browse for a script you receive the error "too many automatic redirections were attempted".
Transaction and Query make standard http calls to SharePoint. Part of this standard process is an initial unauthenticated (anonymous) request. If SharePoint's web application has anonymous authentication turned off, that first request is denied and all subsequent requests will fail.
By default, SharePoint web applications are created with anonymous authentication enabled. Disabling anonymous and forms authentication at the IIS level will introduce issues in the SharePoint environment.
Enable anonymous on the SharePoint web application.
- Log into each web front end server.
- Open IIS.
- Expand sites.
- Highlight the SharePoint web application hosting Winshuttle Central.
- Double-click on Authentication in the feature pane.
- Ensure anonymous is enabled.
