<div class="content wysiwyg-content">
My actual problem is this Runtime error on my application:<br />
<br />
&quot;An error has occurred while establishing a connection to the server. &nbsp;When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)&quot;<br />
<br />
I have gone through lots of instructions and steps:<br />
&gt;ask your ISP to enable TCP/IP to allow remote connections on the SQL2K5 server <br />
&gt;ISP (webprovider): Please run the below command and paste us the result.<br />
telnet 209.132.213.189 1433<br />
&gt;Telnet can't connect to this IP<br />
&gt;ISP (web provider): Some ISPs block outgoing port 1433, please contact your ISP and ask them to open the port for you.<br />
&gt;ISP2 (Internet Provider): We do not block anything. It depends on your local computer's settings. Or you may call Microsoft ... <br />
...Now I don't know what to do? Any hints or help please?<br />
Thanks<br />
