Solution 1

This error appears, If the website is not marked as web application in IIS. for this -> Go to IIS ->Right click your project, Properties ->Click on remove.

If 2 web.config files are present in the same folder.

Please remove one if 2 web.config files are present.

The error is self explanatory. You cannot have one section defined twice in a web.config file.
Remove the line:

XML

<add key="ConnectionString" value="Data Source=10.10.10.144;Initial Catalog=clientbackup;User ID=sa;Password='supp0rt';Pooling=False"/>

from

XML

<appSettings> </appSettings>

section. It should work. :thumbsup:

*edit - added explanation.
