Enter the host name and virtual directory that will be provided in DeficiencyPop URLs. For example, if the URL to the login page is https://hostname/DeficiencyPop/Login.aspx, then the dmsVirtualRoot key would look like the following:
<add key="dmsVirtualRoot" value="https://hostname/DeficiencyPop"></add>
Note:
The host name provided in dmsVirtualRoot must not contain an underscore character ( _ ). If the server's machine name contains an underscore character, use its IP address instead, or change the machine name.
In the Web Application Management Console, this setting is available on the DeficiencyPop tab as Virtual Directory.
