please read this article:
http://www.microsoft.com/technet/prodtechnol/sql/bestpractice/implappfailover.mspx

it contains also sample code.
note that the only part you have to add to your connection string is the Failover Partner.

I repeat:
the only part you have to add to your connection string is the Failover Partner stuff.
in the article they mention that depending on what technology you use, it might be with space or underscore ...

My connection is the following

Connection.Open "Driver={SQL Native Client}; "          &_
      "Server="       & varServerIP  & ";"      &_
      "Database=" & varDataBaseName              & ";"      &_

      "Failover Partner=xx.xx.xx.xxx;"                                                &_
      "Initial Catalog=" & varDataBaseName                            & ";"      &_
      "Integrated Security=True;"

unfortunately, I have no means to set up the same environment to test :(

however, with Sql Native Client:
http://msdn.microsoft.com/en-us/library/ms130822.aspx


Connection.Open "Driver={SQL Native Client}; "          &_
      "Server="       & varServerIP  & ";"      &_
      "Database=" & varDataBaseName              & ";"      &_
      "Uid="             & varUserName      & ";"      &_
      "Pwd="             & varPassword       & ";"      &_
      "Data Source="       & varServerIP       & ";"      &_
      "FailoverPartner=xx.xx.xx.xxx;"                                                &_
      "Initial Catalog=" & varDataBaseName                            & ";"      &_
      "Integrated Security=True;"

Guy Hengel [angelIII / a3]Billing EngineerCommented:
it's not the "same" code... there is no space in the Failover Partner :)
anyhow, if it does not work, that does not really matter ...

sorry, but I don't know more about this.
please use the "request attention" link, so a moderator can try to attract more experts to the question.

i just want to make a note, maybe this will help u,

SQL db is hosted on SQL 2005 Enterprise
ASP application is hosted on another server running Win 2003 Enterprise

the correct syntax is the following

Connection.open "Driver={SQL Native Client};Server=" & varServerIP & "; Failover_Partner=80.93.94.201; Database=" & varDataBaseName & "; Uid=" & varUserName & "; Pwd=" & varPassword

You should not put Integrated Security=True
If you add this , it won't work

However what's the purpose of Integrated Security=True ?

>However what's the purpose of Integrated Security=True ?

that will tell the driver to use the currently connected windows account for login to sql server.
however, in web-driven pages this means that unless you are in a intranet site with anonymeous user disabled, it will not be able to use the front-end user windows account, but it uses the asp/iis service startup account.
