After my two previous posts on debugging offline files, I’ve had four requests via comments and email, all saying pretty much the same thing: “why do offline files stop working after I restart my computer?” The most visible symptom is that the “Enable offline files” checkbox gets cleared after a reboot. I passed this request along to the team responsible for offline files, aka client-side caching, and here’s an explanation from Brian Aust.
These are the checks that are made on CSC startup:
- CSC is not enabled on Home Edition
- CSC is not enabled when terminal server is configured for multiple concurrent users
- CSC is not enabled when either the user’s (admin user) preference or Group Policy says it should be disabled
- CSC is not enabled when either of the following REG_DWORD registry values is set to zero:
ONLY if all those conditions are met will the checkbox stay enabled over a reboot — so if you’re suffering from this problem, those are the four things to check!
Update: for additional things to check, see the comments below, and this later blog post.
Edit: I've turned off comments on this thread - if you have a question, please go here instead.
