this issue has been going on for quite a while, below are the steps we have currently taken.

•      Attempt general Microsoft Update.
o      Some packages updated successfully, others failed
•      Review of Update logs - failures have been going on since 13/01/10 - initial failure was .Net Framework 3.5 Family Update.
•      Enable MSI logging (KB223300). New download of .net SP1 and retry installation manually.
•      Win2008 SP2
o      Not currently installed. Possibly required as part of this issue. Best practice requirement.
o      Attempt install Win2008 SP2 - failed due to <5GB free on C: drive.
o      Analyse disk usage.
o      Move WSUS content and DB to D: drive. (WSUS tools to migrate content. MS SQL tools to disconnect and reconnect DB.)
o      Install Win2008 SP2 - successful
•      Retry .net 3.5 SP1 install - failed.
•      Use links from MSDN to Powershell script designed to target this problem
o      Script run
o      Attempt .net 3.5 installation (from clean download). Failed.
•      Set up remote access (restricted source IP).
•      Use manual procedure from MSDN to apply Stebner .net cleanup tool
o      Procedures apparently successful - log review shows multiple actions
o      Stebner .net verification tool confirms clean .net 3.0 configuration
o      Attempt .net 3.5 installation. Failed.
•      Attempt Guyette/Zorelda procedure, including process checking and manual registry "Installer" review. Changes reflecting Windows 2008.
o      Procedure fails at .net 3.5 installation fails.



The install log from the above App error log is attached.

any help greatly appreciated as we are getting close to just reinstalling the whole server - not fun.

thanks
