Connection For Clustered Server

We have having a problem connecting to our 4 node cluster using an ado.net connection.


Here is what we have:





Connection String:





<appSettings>


<add key="ConnectionString" value="workstation id=AH501780;packet size=4096;integrated security=SSPI;data source=XXXXXXXXXXXX;persist security info=False;initial catalog=xxxx" />


</appSettings>








We added in the Web.config file:





<identity impersonate="true"/>


<authentication mode="Windows" />








In IIS 6 we have windows authentication checked.





We get the following error when we try to run the program:





SQL Server does not exist or access denied.


Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.





Exception Details: System.Data.SqlClient.SqlException: SQL Server does not exist or access denied.











We have the SQL Profiler running and we don't see any connection being made. Any help would be appreciated!





Thanks,


Trey
