Rediscover Device not showing my WMI credentials

Howdy,

I have two SNMP credentials and one WMI credentials setup in OpManager. I have some devices that have showed up as Unknown for Device type while others show WIndows 2012 or Windows 2012 R2. I also have some that are in the Virtual Device Category while others are in the Server category. They are all VMs so I don't know why some are in one and some are in the other.

So, I wanted to do a Rediscover on a device that is showing as Unknown. However, when it brings up the screen to pick a credential to use, it only shows the two SNMP credentials and not the WMI credential which is that one I want to use.

I went under Credentials and did an associate to link the WMI credential to all the machines but that didn't help.

Anyone know what I need to do to be able to tell this item to rediscover and choose the WMI credential? And anyone know why some VIrtual Servers show up as Virtual while some show as Server?

I don't want to have to manually reassign dozens or hundreds of machines to get them all in the same place.

Thanks!
