SCOM Troubles
I inherited the SCOM project when one of our Admin people left the company. This person had done a ton of work setting things up but ran into some problems. One of the problems was identified as databases missing from particular instances. I investigated further and found that the database list was "distinct" across instances. Meaning, if two instances shared the same database name, only one of the databases was listed. After getting an email from PSS, I did more investigation today. Now it's getting weirder. Some servers aren't showing up in Explorer, some aren't in both Explorer and the console. Not good. I've documented it all and shipped it off to the PSS guys to see what they think.
