Hi folks,

I'm configuring a Dynamics Portal. Last time I checked the portal everything was working fine however I now get the following error:

The remote server returned an error: (401) Unauthorized.

There are also some source errors stated as below:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Any help would be greatly appreciated.

    Thanks,

    Hi all,

    Microsoft investigate the issue and advise that the Portal had disconnected from the Dynamics Instance. We had to restart the portal and update the instance. Don't worry this doesn't update the version just refreshes connections to other applications (e.g. the Portal).

    Thanks,
