Re-initialize Windows Offline File Cache

Re-initialize Windows Offline File Cache


The offline file cache or Client-Side Caching is different from the actual file in the file server. When you look at the property for the offline mapped drive, the file system shown as CSC-CACHE. The problem is some of the the offline mapped drive/folder work but only certain folder not working.


We have to clean up or re-initialize the local cache file so that the offline folder/drive will be re-sync from the server. All the local cached files will be deleted. Here is the command:

Platform Command
Windows XP REG ADD “HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\NetCache” /v FormatDatabase /t REG_DWORD /d 1 /f
Windows Vista/7 REG ADD “HKLM\SYSTEM\CurrentControlSet\Services\CSC\Parameters” /v FormatDatabase /t REG_DWORD /d 1 /f

Computer Cloning with similar SID might cause network problem

Computer Cloning with similar SID might cause network problem

Using Disk Image Cloning (e.g. Symantec Ghost) for mass desktop rollout/deployment can significantly saves hours of work and hassle over other rollout method but it might cause major network problem if every cloned system has an identical Computer Security Identifier (SID). This fact compromises security in Workgroup environments, and removable media security can also be compromised in networks with multiple identical computer SIDs.


1. Un-join from Windows Domain or Active Directory
2. Restart computer
3. Download and extract into local computer.
4. Run newsid.exe as shown in screenshot below to generate new SID

5. After computer restarted, join the computer back to Windows Domain or Active Directory


Alternatively, you can run the command below with system prompt:

newsid /a [newname]
