Cannot connect using mixed authentication

  • We are attempting to deploy a SQL Server Express 2012 application in a network using Workgroup networking, and as a result are having to use SQL Server logins rather than Integrated security. All works as it should when connected to the PC running SQL Server. However when we attempt to connect from another Win7 workstation using ODBC, we either get timeout errors, or we get the message that SQL Server actively rejected our connection attempt (we are using Native Client 11 as the ODBC driver, both on the SQL Server PC, and on the network PC). We are also getting Error 8 - "The SQL Server Browser service was unable to process a client request" logged in the Application Log on the SQL Server PC in some attempts, but not in others. Any suggestions on what might be causing the problem? We've done this sort of configuration previously using SQL Server Express 2008 and gotten it to work, but we been banging our heads on this for 3 weeks now, and exhausted all of our usual bag of tricks. Thanks in advance.

  • Any errors in the SQL Server log? Also, what happens when you try telnet servername 1433 from the Win7 machine? It should allow the connection and give you a blinking prompt, otherwise it will just fail to connect and you'll know its a firewall or network connectivity issue.

  • Well, it seems it has to be a connectivity issue. I disabled all the firewalls (the machine attempting to connect has two - Windows and Kaspersky), and still cannot get telnet to work. However it works just fine on port 80. I suspect it is some sort of setting in the DLink router, but what it is remains a mystery. I'll post the cause if we ever find it.

  • Hi WendellB,

    Know this was yesterday, but as a thought have you checked through all of the config tool settings around the protocols and the ports? I recall having a weird problem with Express where the browser wouldn't pass off to it when it was running on a dynamic port and you might be seeing the same sort of thing. Of course you might not too, but it's worth a shot 🙂
