Monitor Windows Server 2008 DHCP

The first thing that I would ask you to check is whether the SNMP service is installed and running on the server and make sure with the SNMP tester that you are able to read the uptime of the device. If you can read the uptime from the PRTG server using the SNMP tester, then the SNMP service is set up correctly.

If it is but you still cannot read the value you want, try and walk the OID's in that article i.e. walk 1.3.6.1.4.1.311.1.3 and post back the results.

Hello, this is the result ----------------------- New Test ----------------------- Paessler SNMP Tester 5.1.2 20.02.2014 19:21:47 (21 ms) : Device: 192.168.0.105 20.02.2014 19:21:47 (31 ms) : SNMP V1 20.02.2014 19:21:47 (42 ms) : Walk 1.3.6.1.4.1.311.1.3 20.02.2014 19:21:47 (66 ms) : Error: 5

ANy ideas?

What happened when you ran the uptime scan? Did you get a result? Have you checked out this article about setting up SNMP on Windows?

Yes uptime gave a result

Paessler SNMP Tester 5.1.2 21.02.2014 11:14:18 (20 ms) : Device: 192.168.0.105 21.02.2014 11:14:18 (31 ms) : SNMP V1 21.02.2014 11:14:18 (42 ms) : Uptime 21.02.2014 11:14:18 (59 ms) : ------- 21.02.2014 11:14:18 (79 ms) : DISMAN-EVENT-MIB::sysUpTimeInstance = 16179256 ( 44 hours 56 minutes ) 21.02.2014 11:14:18 (94 ms) : HOST-RESOURCES-MIB::hrSystemUptime.0 = 3681475109 ( 0 seconds ) 21.02.2014 11:14:18 (105 ms) : Done

Ok, Update: SNMP Walk over 1.3.6.1.4.1.311.1.3.2.1.1.2 works now, but when I do the same check with the field "Custom OID" above it says No such name Also PRTG returns "No such name".

Any ideas?

The issue that you are having is that the OID 1.3.6.1.4.1.311.1.3.2.1.1.2 is a base OID that then has other indexes for information. If you want to get a specific value from the server, you would need to use one of the sub-oid's from that base OID as a custom OID in the sensor and then it should work. If you post the result of the walk I can explain which is which better.
