Months ago I had a Windows 2008 (standard edition) server which had to be upgraded to Windows 2008 enterprise. The enterprise edition of Windows allows templates to be duplicated and changed so that custom validity periods can be chosen or that a smaller key size can be set.
After the upgrade the duplicated templates couldn't be issued. Always keep in mind that these templates are stored in AD so they might take some time to replicate. Nevertheless, I seemed unable to issue those templates. Then I stumbled upon this post: Windows PKI blog
Which provided the following solution:
certutil -setreg ca\setupstatus +512
net stop certsvc
net start certsvc
And now Microsoft issued KB967332 5 months after that post.
