did you install a SP or CP recently? Try running Coredbutil.exe /Buildcomponents on the Core to set the DB straight.
No we haven't run that. Instead LANDesk advised we updated to SP3 as this will perform the coredbutil.exe. Unfortunately this hasn't done the job.
I sure you have, but have you tried creating one from scratch and does the account you are logged on to have the rights to do this task?
yep able to create one but not able to add to the templates. The account has full admin access. Have tested with a "super" account as well.
When you create a new template, are you choosing "Empty Template", "Deploy Template", or right click new template?
