Offline files keeps disabling by itself!

[woody]

Set up a new laptop yesterday for the deputy head. I have group policy set to allow staff to configure offline files if they so wish. On all other laptops, teachers can right click on 'my documents' (which is redirected to the server) and 'Make available offline'.

 

This was not available on the new laptop after it had been joined to the domain. The option to enable it in folder options was greyed out. I logged on as myself and I was able to enable offline files from the folder options box. Then logged back on as deputy, and 'Make available offline' was there, so selected this, syncronization occurred and everything was hunkydory. Until he went home and found he could not even access his 'my documents'. Turned out that when the laptop does a restart or is shut down and started back up, offline files is disabled again.

 

So then started to look into whether group policies where fully applying. I ran a report from Group Policy management on the server and it tells me that the security part under computer configuration failed. The reason given was: 'No mapping between account names and security IDs was done.'

 

I'm not sure if this has anything to with the offline files problem, but I want to get this sorted too.

 

Has anyone got any ideas?

Sounds like a GPO issue.

I would remove the laptop from the Domain, delete the computer account in AD and add the laptop back to the Domain.

 

This will basically recreate the security mapping that may be corrupt.
