Last heartbeat time is not getting udpated

 Hi,

We are using MOM 2005 with SP1, and one of the client's last heartbeat time is not udpated in the MOM admin console. This client is behind the firewall and we have opened TCP 1270 -- from client to MOM server and UDP 1270 --from MOM server to client.

Please advice on this.

See my article on this on myitforum. http://www.myitforum.com/articles/2/view.asp?id=10273 specifically this part: 

A problem that I've run into more than once
A DMZ host does not ever send a heartbeat, or the heartbeat stops updating information to Management server.
This is usually a problem with UDP port 1270 going from the DMZ agent to the Management Server.

Get the mom 2005 reskit, use the mom network pre-requsite checker from the dmz host to see if it can get thru port 1270.

Hope this helps.
