NIS 2013 20.3.0.36 Live Update not working - only Pulse updates completing

Hi there

 

My NIS has been working fine until this morning. Now on live update only the pulse updates are successful. Everything else is failing to complete.

 

I'm running NIS 2013 version 20.03.0.36.  Windows XP SP3.

 

Is there a problem with the Norton server?

 

Any help would be appreciated.

Thanks
