This all started as a side project of me bringing up SCCM 2007 on an extra server. However I still have not gotten past getting WSUS working correctly.
After installing Server 2012 I installed the IIS and WSUS features and had no issues but then found that report viewer 2008 was needed so I had to add .Net 3.5 and include the 2.0 that Report Viewer 2008 is dependent on. This has not gone well. Simply adding the fetures from the GUI gets half the bar filled then fails with a source file error, unable to locate. I then redid it and defined the location d:\sources\sxs this had the same results.
So I tried in an elevated PS the DISM command:
Dism /online /enable-feature /featurename:NetFx3 /All /Source:D:\sources\sxs /LimitAccess
This always failed at 66.3% with Error 0x800f081f I know the source drive to be correct and my rights to it are...
