Authentication Credentials Error

What
Use this article when a Windows imaging deployment fails on the IVS with this message:
“IVS request for URL: https:<your.IVS.IP.address:20044/imagingwindows/boot/get_image_info/ failed with code: 403 Authentication credentials were not provided.”
The error blocks Windows image deployment because the IVS and FileWave Server need to re-establish their secure connection.
When/Why
This error usually means the IVS shared key no longer matches the key trusted by the FileWave Server. Regenerate the key, then verify that the last four characters changed so you know the IVS is using a new shared key.
How
Navigate to FileWave Central (native admin)
Open the Imaging tab
Highlight and double-click on your IVS
Check the box to “Generate new key on Save”
Press OK to save
Click Monitor while still viewing the Imaging tab preferences
Click on Verify to have the IVS check-in
After the IVS verifies successfully, try the image deployment again. Confirm that the image association is set to True before PXE booting the target machine.
