Hi:

This night our server monitor gets the following error message:

I had never see it before, 

Anyone knows what could have happen and how can it be fixed?

Looks like an outside bot looking for ways in. Dynamicweb does not use telerik. Maybe something custom?

Hi Nicolai:

 

I am not using anything related to telerik. I think as you Nicolai , something o someone tried or tries to do something on the server.

Thanks for your answer. I will keep checking the monitor.

 

Regards,

Jose.
