SNMP Network Device Discovery not working

Hello

I have a LAB setup with SCOM 2012 R2

I have

1 x  Management Server
1 x SQL DB Server (The SCOM DB Server)
1 x  Windows 7 Computer
1 x Windows 2008 R2 Domain Controller (i.e. test LAB domain)

I do not have a network device (e.g. cisco switch etc.) but want to learn/try/test SNMP discoveries in the LAB.

So installed and configured SNMP on the DC (no SCOM Agent the DC) and setup the relevant Read-Only community string.

I also installed SNMP on the Windows 7 Server using the same Read-Only community string

I installed an SNMP MIB Brower utility on the Windows 7 computer, loaded the HOSTMIB.MIB from the C:\Windows\System32 directory on the DC

I can now use query the DC from the Windows 7 computer using SNMP e.g. get the UpTime for the DC for example. Therefore I know SNMP is setup and responding to Get requests on the DC using the community string I used for this test.

I installed the SCOM Agent on the Windows 7 computer and all looks OK (green healthy no errors in the Operations Manager log, on either the Windows 7 computer of the Management Server).

Using the Discovery Wizard I went through the motions of setting up a Network Device discovery (I created a RunAs account which uses the same community string as the Windows 7 computer and the DC). I entered the IP address of the DC as the device I want to discovery etc..)

All appears to be working in as much as the discovery runs with no errors (has run twice now) there are no errors in the Operations Manager logs and the RunAs account is distributed.

However I am not seeing the network device appear under network devices or discovery inventory "network device"

I have also checked under "pending management" for Network devices nothing there

Any advise most welcome please
