​​For some reason the AUTOASSIGNED Network Devices may not pick up any DNS Pointer Records and will assign an arbitrary name that you may not be able to locate anywhere.  Very strange….

 

MIB2 doesn’t match the Display Name or Full Path Name.  Nowhere can we find any record for the Verizon Hostname as their network doesn’t touch Verizon.

Router properties of pool-100-1-7-2.nwrknj.fios.verizon.net
Display Name pool-100-1-7-2.nwrknj.fios.verizon.net
Full Path Name pool-100-1-7-2.nwrknj.fios.verizon.net

 
In this case, you may be using the MIB2 System Name, I’m just going to tell the config file to use that instead of AUTOASSIGN.
Discovery Configuration Settings
The configuration file is located in the file discovery.conf in the folder C:\Program Files\System Center 2012\Operations Manager\Server\NetworkMonitoring\conf\discovery. There are several settings that can be configured here, but the important one for this configuration is the DisplayFormatName setting.

If any settings are changed, you will need to restart the System Center Management service (HealthService.exe) on the network discovery server for this to take effect, and you will also need to rediscover the device.
