Am a little bit confused about your instructions on upgrading from 4008 to 4015.Do i need the 4015 disk to do this task?
Perhaps I should explain what I did.Inserted the current 4008 disk and was able to do an upgrade.Then went to the Windows update site to try an update to 4015,but no go.The message said the update page was not accessible.
It would appear that I need the 4015 release.Am I right?

cheers
