Offline Files

Question

Hi Folks,

When I try to start the service "CSCService", I get a failure, "The offline files service has terminated with the following error: The system cannot find the path specified."

It is not clear the specific path, since the error message does not explain which path cannot be found, however "C:\Windows\CSC" is there, and the registry entry HKLM/SYSTEM/CurrentControlSet/Services/CSCSerivce mentions nothing except C:\Windows\System32, which, of course exists and can be found.

Is there a convenient way to reset -- maybe uninstall and re-install this service?

Thanks for the help,

Chris.

@Gary Nebbett ,

I seem to have stumbled into a working Sync. I credit the "System Reset", but there is much more to be done after that. The service must be changed from "Disabled" to "Automatic" and then I had the option for each folder to "Make Available Offline" Ta-Da!

Thanks for the help.

Chris.

Hello @cjm51213 ,

There is more to starting Offline Files than just starting the CscService. What does the Control Panel "Sync Centre" "Offline Files" dialog say about the state of Offline Files?

One possibility is that the path that could not be found is the path to the device object created by the "Offline Files Driver" (csc.sys).

@Anonymous ,

1.Make sure you have grant NT AUTHORITY\SYSTEM full permission on C:\Windwos\CSC and all of its subfolders. When domain admins already have access, you could use the GUI to grant necessary access to all objects in the directory tree C:\Windwos\CSC; you can later remove Admin permissions as well to get back the default security.

I do not find "NT_AUTHORITY\SYSTEM", but I do find "SYSTEM" and it has "Full Control". How do I grant "NT_AUTHORITY\SYSTEM" Full Control? I had to take ownership of the directory and subdirectories. Who should I restore ownership to?

2.Re-initializing CSC database:

To re-initializing, use the configure the registry as below and then restart the client

HKEY_LOCAL_MACHINE\System\CCS\Services\CSC\Parameters
Key Name: FormatDatabase
Key Type: DWORD
Key Value: 1

I have completed this, and re-booted, but nothing has happened. I still see artifacts in C:\Windows\CSC\v2.06... Additionally, the registry entry is still there and I'm under the impression that re-initializing the database will remove that entry. Can't I simply delete everything below C:\Windows\CSC\v2.0.6... ?

I have other observations:

After re-boot, the registry entry is still there and nothing has changed in C:\Windows\CSC\v2.06...

When I try to start the service from the command line:

When I try to start the service from services.msc

Hi,

What's the OS version of your windows? Please refer to the following steps:

1.Make sure you have grant NT AUTHORITY\SYSTEM full permission on C:\Windwos\CSC and all of its subfolders. When domain admins already have access, you could use the GUI to grant necessary access to all objects in the directory tree C:\Windwos\CSC; you can later remove Admin permissions as well to get back the default security.

2.Re-initializing CSC database:

To re-initializing, use the configure the registry as below and then restart the client

HKEY_LOCAL_MACHINE\System\CCS\Services\CSC\Parameters
Key Name: FormatDatabase
Key Type: DWORD
Key Value: 1

Note: Re- initializing CSC database will remove any un-synced data. Ensure share in sync or take a backup before re-initializing the cache.

Best Regards,
Candy
