Sudden Probem with accessing via Lan.

[rbmcgee]

Hi all,

I've always been able to access NPVR (on the server) via firefox at http://192.168.1.204:8866/Guide2.aspx.

Suddenly I'm faced with the following error:

Server Error in '/' Application.
Root element is missing.
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.Xml.XmlException: Root element is missing.

I can access the server just fine and everything else on the server (and on the client) are working fine.

Can someone give me some advice?

Can you access the web server directly on the server? Ie http://127.0.0.1:8866/Guide2.aspx from Firefox (or IE) on the server.

It might also help if you zip and post the Logs folder after a failed attempt.

Hi,

The error posted above was actually from the server. Here is the error from a machine other than the server:

Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".


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

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


Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.


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

<configuration>
<system.web>
<customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
</system.web>
</configuration>

I will post the web.log in a sec.

Here is the web.log

Can you also compress and upload config-web.lxml from the DataDirectory?

[rbmcgee]

Here is the config.web.xml

[mvallevand]

It is corrupt, do you have a back-up?

Thanks a lot Martin. I dug an old version of config.web.xml out from a prior image file, copied it over on top of the existing file, rebooted the pc and all seems good.

Once again, thanx.
