Agent install in MOM2005


Have been trying to implement MOM 2005. I am unable to install agent on a machine that is beyond a firewall with MOMagent.msi. I get an error saying 'Unable to connect to the server'. However if i try installing agent from setup.exe and then select MOM Agent Install tab and follow the wizard after clicking the agent install link, the agent does get installed but shows up as unmanaged!
But any agent install with MOMagent.msi in the same dmz works just fine and shows up as managed.
Can anybody tell me why?

I think I understand you, so here it goes..

Any server you wish to manage that is inside a firewall must have the agent installed manually from either a TS admin session or directly at the console.

Once the agent is installed is should communicate with the DCAM fine as long as you can resolve the DCAM's name from the managed server, there is nothing blocking the communication and there is a form of Trust existing (since MOM 2005 agent uses mutual authentication).

I have been trying to install the agent manually through a TS admin session, but like I said before, beyond a dmz, it cannot find the server if I use MOMAgent.msi . I have to go through the setup.exe and click on the link which actually calls MOMAgent.msi . It works the long way but not the direct way. Why cant i use MOMAgent.msi in a different dmz. Also , to get a heartbeat from the agent, is it necessary to open UDP 1270 port? I do have TCP 1270 open.
Can you ping the DCAM from the server you are trying to install the agent on?

You must be able to resolve the DCAM computername either by NetBIOS or FQDN or the agent won't be able to find it.

Hey, thanks for the quick replies!. But I am afraid that the issue is still not clearly understood. Let me make it very clear. Yes, I am able to resolve the MOM server computer name. My agent does get installed but ONLY through setup.exe. However after getting installed, i dont get any heartbeat from the agent. Do i need UDP 1270 open?
I also would like to tell you that now the agent shows up as 'managed'. I just deleted the present entry and reinstalled agent again.
Also, plz clarify if DCAM in MOM 2000 is the same as my MOM 2005 server. I am sorry if this question sounds stupid, but I am fairly new to MOM.

Hey!
That is some useful info. Well, checking these ports is gonna take time. So i will get back to you on mon/tue. Let me get all the approvals to open ports which are necessary and see what happens.
VPN would not be feasible in our IT environment now so I have to deal with the firewalls here.
Good stuff.

I think, just for management purposes that port 1270 TCP/UDP both directions is all you will need.

Let us know how you make out.

Hey!..
looks like opening the port is gonna take time..i dont want to keep u in the dark for all that time!
Looks like tht is the only thing left out n it shud work thereafter..so i wud like to close the question.
Also, would appreciate if u cud provide any handy tips Thanks a lot!!!!
No problem.  What tips would you like?  There isn't much to all this - it either works or it doesn't!  Just keep your MOM DB size down.  Run a pruning job every week - either archive or delete the old info.

Let me know what else you might want.

Cheers.
