I upgraded to DNN 4.4.1 over the weekend, and since the upgrade, the Forum Module is not working. I get the following error on all pages with the forum module on it:

A critical error has occurred.
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

and in the log viewer, I get the following error:

As I said earlier, I am running DNN 4.4.1 and Forum version 3.20.08. The problem did not occur until after an upgrade from DNN 4.3.4. The site runs on Windows 2003 Server with IIS 6 and SQL 2000. I also run with Active Directory Integration and Windows Authentication. No other modules are having this error that I have found. Thanks in advance for the assistance.
