For the last year we have been using a W8.1 laptop for specific functions by a remote user. We connect to the network through a SonicWall VPN, and then use RDP to login to the PC.
We have been using a local account (no MS account) for all this time without issue. Let's say that local account is "SAM"
Today, we are able to establish the sonicwall connection - but cannot login as SAM. We can connect with another username that IS a MS account i.e. firstname.lastname@example.org, but not as SAM.
There was a MS KB installed two days ago... I uninstalled it, rebooted, and tried again. No change.
HOWEVER, if I use SAM as the username, and type in the password for one of the MS accounts, I can login... but I am logged in as one of the MS accounts. Did this twice, because I did not believe it. Somehow "SAM" got associated with a MS account.
Now the question is can that association be broken.
