Hi CPEARS, Thanks for the details in your post. I will suggest to check one thing here: - Go to Settings->Discovery Settings and check what "Discovery Wizard Configuration" is selected. Whether it is "Standard Wizard"? If yes, can you try switching to "Guided Wizard" and whether adding the new discovery range works with Guided wizard? Thanks,Vijay  
I upgraded to OME 2.1.0.265 and have upgraded my Silverlight (v5) but it seems Silverlight is giving me a horrible time.  I cannot utilize the Finish button when adding a range with WSMAN to add a new Discovery Range  I've tried the webpage in multiple browsers, Chrome/Firefox.  I've tried on IE8 and IE11 as well.   If I just add a range in and use SNMP it will add.  But as soon as I utilize WS-MAN the finish button depresses but does not remove the configuration screen, therefore, the range is never added.  I have to just add SNMP and Finish and the go back and edit the configuration.  I can still see an error on the page in IE.  I have to click on the upper right hand X to exit the screen. Anyone else experience this issue?
