Connection pooling not working in Clustered Env.

Hi,
We had deployed a .NET application in a non clustered environment with conection pooling and was working fine. Now we had moved to a clustered env and connection pooling stopped working. Is there any cluster aware setting that we need to look at. Please let me know your thoughts.
Thanks in advanceCan you be more specific on what went wrong? Any error code, exception stack will be helpful.sqlsql

Connecting to SQLExpress from classic ASP.

Migrating a site to a new server. Moved data to SQLExpress. Changed connection string to point to SQLExpress and now I am getting this error.

Microsoft OLE DB Provider for SQL Servererror '80004005'

Cannot open database "PHCSQL" requested by the login. The login failed.

Do I need to do permissions differently than MSDE?
Did connection strings change?
Help?

Hi,
Download the full eval version and install it as a named instance and register the Express. How install the full version management studio which is a separate install and right click at the top to register the Express. Then create permissions for Asp in the security section of management studio. Another option is to just restore the backup .bak file of the MSDE with the backup and restore wizard and choose the restore from a device option. Try the links below to download the eval verion and connection strings including old style connection strings. Hope this helps.
