Problems adding datasource in ColdFusion 8.

Hello,

I am trying to add a new datasource to ColdFusion 8 which is installed on Windows Server 2003.  Its not a new install and many other datasources have been added previously.  When I try today, I type in the Data Source Name and select Microsoft SQL Server as the driver type and click add.  Usually this will bring up a new screen where I can type in the details for the data source but now all it does is refresh the screen but not add the datasource.  Another weird thing is that if I click Verify All Connections, the same thing happens.  I can verify each individual connection and edit existing connections without any trouble.  I have tried restarting the ColdFusion services but this has not helped.

Any ideas that can be given would be appreciated.

Thanks!
