SharePoint 2016 Site-wide Anouncement

There are tons of tutorials on how to add an announcement banner using PowerShell or custom web parts, but why go through all that when you can use plain-old CSS to get the job done via the UI?

If you browser to the Master Page section within the Site Settings area, there is an option titled “Alternate CSS URL”. Within the file used here, you can easily add the following CSS to inject a quick announcement to all of your SharePoint pages:

#suiteBarDelta:before {
    content: "[Enter desired text here]";
    display: block;
    padding: 10px;
    color: #000000;
    background-color: #ff8383;

Apply your changes and refresh the page to see your announcement on display.

SharePoint & “The HTTP Request was forbidden with client authentication scheme ‘Negotiate'”, Event ID 8306

If you find yourself running into this error, here’s one solution that you might not find elsewhere (at least at the time of this writing). Check the SSL Settings > Require SSL checkbox for the SharePoint Web Services site and the SecurityTokenServiceApplication subnode. Make sure that it is unchecked as SharePoint accesses it locally over port 80.

This is an obscure self-own, but if you like to set your IIS configuration via script, it’s easy to accidentally set this and (seemingly) brick your WFE.
