Windows 10 update 1903 | IIS Print | Stop work
Hello,
We use IIS Printing solution as follow:
- Running on-premise IIS Print Server with Authentication settings to use Windows Authentication
- Redirect on-premise HTTPS URL using Azure Application Proxy with Pass-through option
- Users, use generated URL and add printer to AzureAD joined computer, using their Windows credentials
After Windows 10 updated to 1903, this solution no longer works.
If browse from IE/EDGE/Chrome = authentication works fine with current username and password,
If use Control Panel to add printer via HTTPS protocol, then it fail.
Using Fiddler could find: 401 - Unauthorized: Access is denied due to invalid credentials,
Any ideas what to check?
