Change of IP address , Error detected by Database dll error

[donv]

Hi all!
I would like to know if change of IP address of the remote m/c hosting web component server effects web reports ? This is because all the reports prior to the change of IP are working but not the later ones.(I checked the ODBC connnectivity vis-a-vis the new IP of the database server, the connection is successful)Should the WCS be re-installed ? I have been getting the "Error Detected by database dll" for all the new reports.I request help.

Thanks
donv
