We are in the middle of an SL 2018 test upgrade for a new client. The upgrade procedures ran well, but when trying to logon we are unable to connect to the SQL server. The SQL Server resides on another box, is a default instance and is operational. In troubleshooting we've done the following;
1) Restarted SQL Services
2) Verified Port 1433 and 1434 were open on windows server firewall
3) Tested with the firewall off
4) Checked the CLICONFG utility, made sure TCP/IP and named pipes were enabled
5) Tested the order of TCP/IP and named Pipes
7) Verified server could be pinged from TS Box
8) Tried setting up an alias
9) Tried connecting with the iP address instead of the server name.
10) Verified I could make an ODBC connection using SQLNative Client 11
In each case was unable to complete a successful logon to SQL Server. The process errors out with a System Message 5003 and the following message detail: "Unable to open the specified server database CVMDSQL ( 66)
I am running out of things to check. Is there something I may be missing. Please advise. Look forward to a response.
