This is SQL Server 2012SP4 on Windows 2012R2, with .NET Framework 4.7.02053.
I've RDPed into the database VM and open SSMS.
- It times out with this error the first time I try to connect.
- If I try again, it works.
- If I increase the connection timeout, it works.
But why is it happening locally? This migrated from SQL Server 2008 and Windows 2008R2 and did not have this problem. Since a canned application that can't specify the connection timeout is failing, we need to solve this.
IPv6 is disabled both at the Windows level and in SQL Server Config Manager.
