Had this issue today (and a few months ago). I open vCenter client, type in the vCenter server name, tick “Use Windows Session Credentials” as usual, and login fails. Says it cannot login with the given credentials.

Fix for both times was to reset the secure channel by logging in to the vCenter server –
