OpsMgr and Windows 2008: What hotfixes do I apply?

Even though the related KB articles seem to be clear on this topic (KB953141 and KB954049), I do get questions about what hotfixes to apply when running Windows 2008.

Many times the cause is to be found in KB954049 which also has some prerequisites to comply with of which most hotfixes do match the hotfixes as mentioned in the other KB article.

On top of it, people ask me when to install these hotfixes, or better, with what OpsMgr (server)roles. Actually, these hotfixes (if applicable) need to be installed for any OpsMgr server role or Agent.

With answering the question what hotfixes to install the version of OpsMgr comes also into play, as well the SP level that Windows 2008 is on.

With two tables I hope to clear things up. But first take a good look at #1:

1. OpsMgr hotfix KB954049 is only needed when OpsMgr isn’t at R2 level.
   
   
2. Needed W2K08 hotfixes based on KB953141:

   W2K08 before SP2 level	W2K08 on SP2 level
   KB951327 KB952664 KB953290	All the in the left column mentioned hotfixes are included in SP2 for W2K08. So they don’t need to be installed.

   
   
3. Needed W2K08 hotfixes based on KB954049

   W2K08 before SP2 level	W2K08 on SP2 level
   Besides the earlier mentioned hotfixes in the first table, also KB951116 is needed.	All the in the left column mentioned hotfixes are included in SP2 for W2K08. So they don’t need to be installed.

So when running OpsMgr R2 on Windows 2008 servers at SP2 level, none of the mentioned hotfixes (for OpsMgr or Windows 2008) is needed.
