We are running Office/BCM 2010 and had a machine previously working and upgraded it to Windows 10 Pro from Home via the Windows store and in the process the user account changed from a local account to a Windows account. We changed the account back to local but it still isn't able to connect to BCM (getting the user hasn't been granted access or password mismatch messages). We've checked the passwords on both, and also created a new computer user account on both the workstation and server (also Win10 Pro) but still getting the same message. The firewalls are both turned off on both. All of the accounts are local administrators and we did reshare the database for the new account.
