After upgrading the probe device from Server 2003 to Server 2008 R2, some of the custom SNMP sensors on the LAN are returning error -2003. I have tested using Paessler SNMP Tester 5 and receive the same result. When I try to select the option to just "Read Device Uptime" it also fails.
- The Windows firewall is not enabled on either the probe or the target machine. - The new server is sitting on the same IP address as the old server, so firewalls are not an issue anyway
Any idea what changing out the probe device would do? Is there a piece of software that needs to be installed on the probe that we didn't install?
