title: mirroring state of the database went to disconnected state in SQL Server 2008
body: <p>I have 4 databases mirrored using High Protection mode without witness server between two servers(principal and mirror) that are in the same domain. Manual failover worked fine for several days. But later somehow the IP of the principal server was changed in the DNS, then onwards the mirror state of these databses went to disconneted state and it remained in that state only though I did change the principal servers IP to its original in the DNS server.</p>
  
  <p>Why it remained in disconnected state and how to make the mirror state as synchronized?</p>
