Server update 2.2 causes issues with Netinstall

After installing the 2.2 update, our server shows a pinwheel for long periods at the bottom of the Server pane, saying it is checking < fill in any one of the server processes > and when I try to make changes to the images , it doesn't make the changes and the edit image screen does not go back to the image list, unless you press Cancel rather than Done. We rolled back to the previous server app and NetInstall worked again, but our Profile Manager could no longer read the profiles. I assume they got updated in some way, when Server 2.2 was installed and the previous version didn't know what to do. We reinstalled the 2.2 update and the Profile Manager now works again, but the NetInstall is broken.

If anyone has a fix for this, please let me know.
