customers very specific information and the solution is quite simple.

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 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 sql server error 25 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. [Update: If it still fails, you may replace serverinstance with tcp:serverinstance and/or np:serverinstance and see if it succeeds with either TCP or NP protocol. That way, you can isolate the issue a little bit. ] There is one corner case where you may still fail after you checked step 1)-4
