I have SQL Server installed on a local network (non-domain) computer (COMP001) using the default instance with Windows Authentication. I have enabled TCP/IP and set the IPAll port to the default (1433) and allowed incoming communication on port 1433 in the firewall.
I am trying to access the Server from other computers on the network. On the computer with SQL Server installed, I am able to connect to the SQL Server using the default server name (COMP001) but attempts to connect using "tcp:IPAddress,1433" (where IPAddress is the IP Address of COMP001) returns "The target principal name is incorrect. Cannot generate SSPI context." Attempts to connect to the SQL Server from any other computer on the network using either the server name or the IP address method returns the same error.
Using tnc in PowerShell shows that the port is open. Looking at the SQL Server log after connecting using the server name (COMP001) shows that the server is listening on port 1433 and port 1434.
Any Suggestions?
