Someone had installed a OTMwatchdog service on the IT Assistant 6.5 (W2K SP4) server, with that consequence, that IT assistant did not get the SNMP traps from other servers.
I also applied a registry settings (see below) and ServicePack4 for W2K Server, but I don't know if these had any influence on the IT assistant problem.
---
What I did, was the following:
Downloaded Kiwi Syslog deamon http://www.tucows.com/preview/238932.html, and installed it on my WinXP workstation, started it, made the following setting in it: File -> properties -> Inputs -> SNMP -> check the "Listen for SNMP traps" field, and then re-started it.
Added a Trap, in one of our Dell 2650 servers SNMP service, to the ip-address of my XP workstation. Restarted the SNMP service, and pulled the powercord out to one of the powersupplys on the 2650 server, to have the server send a SNMP trap to my XP workstation. This worked well. I could see a SNMP trap com on the Kiwi syslog deamon.
I then installed the Kiwi program on the IT Assistant ver6.5 Management station (W2K SP4) - with all IT assistant services temporarily stopped and deactivated, then rebooted the machine.
Then did the same test with the PowerSupply in the Dell 2650 server, and registrated, that a Trap came to my XP workstation, but not to the IT Assistant machine (with IT assistant deactivated and Kiwi started).
Tried to do the same test to another W2K SP4 server (installed Kiwi on it, added a SNMP trap to it's ip-address), and saw, that this server did not receive the trap.
Then I applied a registry setting that I had found on MS Knowledge base, to this W2K SP4 server, http://support.microsoft.com/default.aspx?scid=kb;en-us;296672, and also re-applied the ServicePack4 for W2K, and rebooted the server. This time the W2K SP4 server (the Kiwi program) did receive the traps from my Dell 2650 server. But I am not sure, if it was any of the to thing (registry settings and SP4), that fixed this.
Then I turned the focus on the IT Assistant W2K machine once again, and installed the Etheral Network Protocol Analyser, to see, if I could see any SNMP packets, wich I did not. I also installed the Etheral Network Protocol analyser on the other Win2K server, and there I could see the SNMP Trap packets.
I updated the network driver on my IT assistant W2K Server machine, and also cross-eksamined the properties for my network card and TCP/IP properties. But this gave nothing.
This was when I began thinking of some other possible service, that was running, that was stealing the packets from both the sniffer, Kiwi and IT Assistant 6.5.
And there it was: Among the services, I saw a OTMwatchdog service.....
I disabled all the OTMxxx services, rebooted the machine, started Kiwi, and provoked some SNMP trap packets from my Dell 2650 server (unplugged on of the redundant powersuplys), and this time, snmp packets began showing up on the Kiwi program. I closed the Kiwi program, rebooted the machine - this time with all my IT-assistant services enabled. And now the alarms all show up on IT assistant.
I write all this long explanation, because I think that it is nessasary, that you get the felling of how I worked through this. Maybe this was a really clumsy way of locating the error. Maybe I should imediately have searched for unknown services... But next time...
I hope that Dell Tech Support will come to the conslusion that there is a better way to solve problems like this. If they do, I also hope, that Dell can provide us with some tools, and procedures, to solve these (SNMP) problems.
You have to go to your snmp services and make sure your community is set up with read/write priv. and also add the server name or IP address of the IT assistant to the trap destinations. Restart SNMP services when you've done this.

Verify that the SNMP Community name is the same on the IT Assistant Console and all client servers/PCs
Hope this hleps,

Hi Martin.
I Just solved our problem!
Someone had installed a OTMwatchdog service on the IT Assistant 6.5 (W2K SP4) server, with that consequence, that IT assistant did not get the SNMP traps from other servers.
I also applied a registry settings (see below) and ServicePack4 for W2K Server, but I don't know if these had any influence on the IT assistant problem.
