title: Cannot connect to remote SQL server
body: <p>A client of mine gave me a server name which is fully qualified <code>[servername].somedomain.net</code>
  to try to connect to their SQL Server instance over VPN.</p>
  
  <p>So I tried, using the username and password they gave me. No luck. I can ping it but cannot connect, I get the error that the username and password is incorrect.</p>
  
  <p>So I log onto the actual server, verify that my login is in security and has rights and it appears there. <code>Workgroup\mylogin</code> and it appears that <code>workgroup\</code> actually is the same as <code>somedomain.net\mylogin</code>. Because when I try to add <code>somedomain.net\mylogin</code>, it resorts to saying that it's already added which is <code>workgroup\mylogin</code>.</p>
  
  <p>Not sure what else to check here. I gave myself sysadmin role in SQL Server. I can ping the server's IP.</p>
  
  <p>I looked at how they are authenticating me and they have my user in SQL Server set up to use Windows Auth. Well, the error I get is that it cannot trust cross domain when trying to use windows auth when I try to connect locally here in my management studio. I'm connected tot their VPN so what could be the problem?</p>
  
  <p>They're not available right now to try to troubleshoot it and I'm just curious what else I might try to try and resolve this on my own if I can.</p>
