This is not exactly correct. Actually, this error message give customers very specific information and the solution is quite simple. First of sql server 2008 r2 download all, you get this error message only if you are trying to connect to a SQL Server named instance. For default instance, you never see this. Why? Because even if we failed at this stage sql server 2008 r2 management studio (i.e. error locating server/instance specified), we will continue to try connect using default values, e.g defaul TCP port 1433, default pipe name for Named Pipes. You may see other error message due to failure later, but not this error message. Every time client makes a connection to SQL Server named instance, we will send a SSRP UDP packet to the server machine UDP port 1434. We need this step to know
Sql Server 2008 R2 End Of Life
configuration information of the SQL instance, e.g., protocols enabled, TCP port, pipe name etc. Without these information, client does know how to connect the server and it fails with this specified error message. In a word, the reason that we get this error message is the client stack could not receive SSRP response UDP packet from SQL Browser. It's easy to isolate the issue. Here are the steps:1) Make sure your server name is correct, e.g., no typo on the name. 2) Make sure your instance name is correct and there is actually such an instance on your target machine. [Update: Some application converts \ to . If you are not sure about your application, please try both ServerInstance and Server\Instance in your connection string]3) Make sure the server machineis reachable, e.g, DNS can be resolve correctly, you are able to ping the server (not always true). 4) Make sure SQL Browser service is running on the server.5) If firewall is enabled on the server, you need to put sqlbrowser.exe and/or UDP port 1434 into exception. Once you are done the steps, you should not see this error message anymore. You may still fail to connect your SQL server, but error message should be different and you have a different issue now.

Everything is set up and configured correctly other than the Firewall. This is the first time I've done this with SQL 2012 and W2012 server. Reading multiple posts here on SU and the MS sites, shows that I need allow port 1433 (TCP). I have done this. When I try to connect to my remote server, I get a fairly common error message Error 26 - Error locating server/instance specified If I then disable the public profile on my Windows Firewall on my W2012 server, I can connect fine. This proves the issue is with the ports some where. What other ports do I need to open / what else do I need to do? Edit I have enable Named Pipes and TCP/IP. windows-server-2012-r2 sql-server-express share|improve this question edited Jul 20 '15 at 7:30 asked Jul 19 '15 at 14:10 MyDaftQuestions 2218 add a comment| 1 Answer 1 active oldest votes up vote 3 down vote accepted Add the following applications to your firewall where SQL Server is installed: C:\Program Files\Microsoft SQL Server\MSSQL11.SQLExpress\MSSQL\Binn\sqlservr.exe C:\Program Files (x86)\Mic
