I have 3 servers, principal, mirrored, and witness. Once I add the failover partner line to my connection string, and shutdown the principle sql server newly created records fail to locate the mirrored server. I have tried all 3 ways of editing the Failover Partner syntax to include an underline (Failover_Partner), a space (Failover Partner), and as one word (FailoverPartner). None of these work. Here is my connection string which works until I add Failover Partner. Any Ideas.
Set objConnection = CreateObject("ADODB.Connection")
objConnection.ConnectionString = "Provider=SQLOLEDB.1;Integrated Security=SSPI;PersistSecurity Info=True;User
ID=logon;PASSWORD=password;Initial Catalog=PCUser;Data Source=server\instance;Failover Partner=server\instance;Network=dbmssocn"
objConnection.ConnectionTimeout = 0
