I have a small home network of pc's all running Windows 10. None of the PC's have been or are in a domain. One (an intel NUC) runs Sql Server and my Surface 3 has Visual Studio. I use my Microsoft login for both. This setup has been running fine for almost 2 years. Now I suddenly get the above error when trying to connect using integrated security.
Sql Authentication works fine. I can also remote into the NUC and run SSMS without a problem. I have followed the troubleshooting guide without success (KB 811889) NTLM seems to be operating OK on the NUC. I pinged -a IPAddress and it resolved correctly to the name of the NUC SQL Server uses NT Service\MSSQLSERVER. I tried using LocalSystem but still didn't work
All the help articles I have found assume there is a domain or suggest Sql Authentication as a solution.
Only recent change has been installing Windows Update for Windows 10 Version 1607 on the NUC
Can anyone help me?
