Hi all I can't seem to receive SNMP traps on my Windows Server 2008 R2 machines.

The Windows 2003 machines all work absolutely fine and are setup in the same way.  There is no antivirus software or firewall enabled. Does anyone have any idea why this is happening? Is it a security feature I need to disable?

Are you sure the windows firewall is disabled ? Also check of the port is not in use. If so here is a link to see which process is opening the port:

SNMP uses port 161 TCP & UDP

Windows firewall is definitely definitely disabled, I've checked and double checked this!

The windows 2008 servers are using the default port 161 for SNMP

It may be better to give an overview of what you're trying to achieve, when you say a 2008 server receiving traps - from what ? are the incidents generated on a diff piece of hardware ? if so what ? and what is the networking configuration you're using.. any extra information will aid in our diagnosis.

Hi no problem. Basically we had an HP SIM server setup on Windows 2003 but recently migrated it to Windows 2008. As HP Systems Insight Manager communicates with all servers via SNMP we noticed an immediate problem after the move. I've been using the Microsoft SNMPutil to test SNMP connectivity between the servers by sending a test SNMP trap from the HP management agents program. This has revealed that the trap is successfully received by all servers except for the one HP SIM is installed on. It's as if SNMP packets are being blocked or intercepted by no firewall is enabled.
