Problem accessing DFS subfolders

User cannot access \\\dfs\company\subfolder. Subfolder is missing, however user can access \\\dfs\home\%username% which has offlinefiles enabled.

When I loggon with my admin account I get access denied when trying to access \\\dfs\company.

It works from other computers however, so the problem is isolated to this specific client.

I found this solution:

1.  Disable offline files
Control Panel -> Sync Center -> Manage Offline Files -> Disable Offline Files

2. Clear the offline file cache
This sets a temporary registry entry which is read on start-up and runs the cache wipe.
Elevated Command Prompt
reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Csc\Parameters /v FormatDatabase /t REG_DWORD /d 1 /f

3. Reboot
You must reboot to successfully wipe the offline file cache

4. Test DFS path

5. Re-enable Offline Files
Control Panel -> Sync Center -> Manage Offline Files -> Enable Offline Files -> Reboot
