    Help with Unknown device

      Hello

      I am currently trialling Orion NPM. When using the network discovery tool, all of my Windows 2003 Servers are listed as 'unknown' and i get very little info from them.  After looking up the issue here, I had deleted the node and attempted to add it manually. SNMP tests okay in the first stage but when i reach the 'change properties' stage i get the following error message:

       

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