Where as SMS has a hugely popular list: http://lists.listleague.com/mailman/listinfo/mssms/ , MOM has a hugely popular newsgroup news:microsoft.public.mom .

And where as SMS requires configuration to get going – all I did with MOM was install the appropriate management packs and add the relevant servers.

Today I’ve already uninstalled our test installation of ACT  – MOM was complaining that it couldn’t connect to the SQL Server Agent on our test server where our test installation of ACT had gone. MOM reported the same message for our SMS box, but the SQL Server Agent

And they said MOM was hard!

(OK – so that kinda sets me up for it to all go wrong - but then that gives me an opportunity to learn!)
