I have a laptop (PC2) and a desktop (PC1) in a workgroup (Windows 7). PC1 is running SQL Server 2014 Developer and PC2 is running SQL Server Express 2014. Using SSMS, I have tried many different ways to connect to PC1 SQL Server, but always get error 18456.I'm obviously new to SQL Server administration. The servers on both PCs are configured for both Windows and SQL Server Authentication. SQL Server browser service is running and enabled. The error log on ASUS-JHS-CM6850 (PC1, desktop) shows "06/05/2015 14:42:25,Logon,Unknown,Login failed for user 'ASUS-JHS-CM6850\Guest'. Reason: Could not find a login matching the name provided. [CLIENT: 192.168.1.15] 06/05/2015 14:42:25,Logon,Unknown,Error: 18456 Severity: 14 State: 5." I'm pretty sure I need to add logins or users to one or both servers, but I've been struggling with this for days now. I also don't know why it's logging in as Guest, nor have I found a way to change that. (I am always in the same admin accounts on both machines)
