One more management pack is released today by MSFT. This MP provides monitoring for Windows Deployment Services in Windows Server 2012. The MP is also supported on SCOM 2012 but I bet you can install it without issues on SCOM 2007 R2. The reason why I think that the MP will work on the earlier version of SCOM is because in the guide there are references for SCOM 2007 R2 all over the document. Even the PowerShell commands written in the document are for 2007 R2 version. I’ve noticed that all recently released SCOM management packs have documents that are not fully updated and reference SCOM 2007 R2 in them. Also in the guides all management pack have a release date from last year (2012). Any way you can download this MP here.
