Windows updates KB958644/KB948109 (critical security updates) + SQL Server 2005 error 53
Posted on 2008-10-27
I am no longer to connect remotely to our SQL Server database after the important updated KB948109 and/or KB958644 were installed over the weekend. In the SQL Server Surface Area Configuration Tool, I was allowing for Remote Connections via TCP/IP. This morning, everything was working as usual, and then all of a sudden it stopped allowing remote connections to the database.
Our .NET web app couldn't connect until I increased the remote connections setting to allow both TCP/IP and Named Pipes to remotely connect. However, I still cannot connect remotely via Management Studio, from a .NET Windows application that uses a connection string to connect to the database, or from another application that uses ODBC to connect to the database. I attempted to install the patches, but the problem is still occurring. We are using SQL Server 2005 SP2, which is installed on a Windows Server 2008 SP1 box.
Any thoughts on if/how these patches are causing the issue, and what the appropriate response is to get my connections working again?
