There was also an issue about changes to the OS (ie fixes) we could not touch anything in LPA as well. This caused a lot of problems (politically). I can’t begin to tell you of how many jobs that ran for days on end, We had to be involved (the systems group) heavily when someone wanted to buy a software package as it could impact check point restart, Its been years and I can’t remember the product and it created political waves around the company as we said “NO”. Just remember check point restart has implications beyond using it. Ed
