MSDE Upgrade To SQL Server 2005 Express Edition SP2

Hi,

I am trying to upgrade MSDE 2000 to MS SQL Server 2005 Express Edition SP2 (Build 9.00.3042.0) using a silent install.
MSDE on our systems is installed as a standalone product. There is only a single default instance (MSSQLSERVER) running on the system. SQL Authentication mode is being used.
When I try and upgrade MSDE 2000 directly to MS SQL Server 2005 Express Edition SP2, the install fails with an error:

"SQL Server Setup Cannot Upgrade the specified instance by using SQL Server Credential. You must use Windows Authentication credential for the upgrade"

When I try to upgrade the default instance of MSDE to SQL Server 2005 Express Edition SP2 selecting Windows authentication (logging in as a domain/local administrator to the server), the install fails with an error:

"Server Setup could not connect to the database service for server configuration. The error was: [Microsoft][SQL Native Client][SQL Server]Login failed for user <mydomain><AdminID>"

However, MSDE 2000 upgrade to an earlier version of MS SQL Server 2005 Express Edition (Build 9.00.1399.6) using SA Authentication works successfully without any errors.

So I tried to upgrade our MSDE installation to SQL Server 2005 Express Edition SP2 (Build 9.00.3042.0) as a 2 step process. First by upgrading MSDE to SQL Server 2005 (Build 9.00.1399.6) using SA Authentication which works successfully as mentioned earlier.

However, when I try and upgrade SQL Server 2005 (Build 9.00.1399.6) to SQL Server 2005 SP2 (Build 9.00.3042.0) using SA Authentication, I receive the same error as before:

"SQL Server Setup Cannot Upgrade the specified instance by using SQL Server Credential. You must use Windows Authentication credential for the upgrade"

When I upgrade using Windows Authentication, the setup displays the following error:

"[Microsoft][SQL Native Client][SQL Server]Password validation failed. The password does not meet the requirements of the password filter DLL.. To continue, correct the problem, and then run SQL Server Setup again"

The log file content for the error is:

The registry entries suggest that the version now is 9.00.3042.0. However, I am not sure if the upgrade was successful. I can connect to the database using the old SA user ID and password.

If anyone else has faced similar issues, please let me know the workaround for the same.

Thanks and Regards,
