TipHKCU\Software\Policies\Microsoft\Windows\
The NetCache subkey contains entries that store Group Policy settings for the Offline Files feature. In Group Policy, these policies appear in the Computer Configuration\Administrative Templates\Network\Offline Files folder.
This subkey in HKEY_LOCAL_MACHINE stores entries related to policies that apply to all users of this computer. There is also a Microsoft\Windows\NetCache subkey in HKEY_CURRENT_USER, which stores policy-related entries that are configured separately for each user.
Also, many the policy-related entries in this subkey take precedence over user settings while the policy is in effect. The affected user settings are stored in HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\NetCache.
Tip
For detailed information about particular Group Policy settings, see the Group Policy Reference (Gp.chm) on the Windows 2000 Resource Kit companion CD.
For general information about Group Policy, see Group Policy in Windows 2000 Help.
