The value of the dmsVirtualRoot key is the root path to the virtual directory of the OnBase Web Server (e.g., http://ServerName/AppNet). The server name as configured in this key must exactly match the server name as it is passed in the URL from the line-of-business application.
If the URL coming from the line-of-business application is changed before being sent to OnBase(by a load balancer, for example), this value must still match what the line-of-business application originally sent, not what the URL was changed to.
For example, if the line-of-business application is sending the URL to OnBase as http://ServerName.network.net/AppNet and the dmsVirtualRoot value is configured as http://ServerName/AppNet this causes a mismatch error even though both addresses point to the same server. To correct this error, update either the URL that is passed to OnBase or the value of the dmsVirtualRoot key so that the server name in both places matches.
To change this key, locate the <add key="dmsVirtualRoot" key under the <appSettings> node and change the value attribute to match the server name as referenced in the URL from the line-of-business application.
