I have a server with three installed SQL Server 2014 instances with Service Pack 1 (build number is 12.0.4213.0) installed. When I run SQLCMD -L on the server I am getting the bizarre response below.
Servers: ;UID:Login ID=?;PWD:Password=?;Trusted_Connection:Use Integrated Security=?; *APP:AppName=?;*WSID:WorkStation ID=?;
The SQL Server is running normally and the SQL Browser service is started. Querying the SQL Browser service with another tool on the same server yields the expected results. I can run regular SQL queries with SQLCMD and get the expected results.
I was able to verify that the output above is the same on a workstation where I caused SQLCMD -L to receive no responses at all by enabling the firewall; however, the firewall is not an issue on this server. I've checked the settings and, as stated previously, my other tool gets SQL Browser Service responses to a broadcast just fine.
Also, running WHERE reports that the path to SQLCMD is
C:\Program Files\Microsoft SQL Server\Client SDK\ODBC\110\Tools\Binn\SQLCMD.EXE, which is correct per File Locations for Default and Named Instances of SQL Server.
Does anyone have any idea why SQLCMD is doing this and how to fix it?
