The thing is, I never changed this error before even though I had to change my password many times. What was different this time is that I had problem with server and had to Stop and Start the instance. As a result the name of the instance has changed. The problem is Remote Desktop had saved the name of the previous instance in the username field in a form "instance name\my name".
Soution: I deleted the instance name in Remote Desktop and the error has gone away. Hurray!

Just to clarify. You need to delete you credentials in Remote Desktop because they include reference to the old instance name. For that
ReplyDelete1. open Remote Desktop,
2. click Options,
3. notice that User Name is prefixed with instance name. You can just remove that instance name and leave your user name.
