Hi, Apologies for my ignorance, Im completly new to DNN. I have installed a standard installation on my server and can view the pages without any problems, my problem is I cant view the pages from any other machine I get the following message:
 
I have no doubt its something simple I have missed - HELP

Server Error in '/ContentManager' Application.

---

Runtime Error

<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="Off"/>
    </system.web>
</configuration>

Apologies, When set to 'Off' I get this message:

Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Source Error:

   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +64

Is there anybody out there that can shed any light on this error ??? All I have done is the standard install. Don't want to ditch DNN as it will have great benefits to my business but it will be pretty pointless if it cant be viewed on any machines.
