Offline files (CSC service) keeps crashing

December 30, 2012 at 01:39:12
Specs: Windows 7

Hello

We had a Windows 2003 server and Windows XP and 7 Pro SP1 clients who use offline files perfectly (files stored on a NAS which is joined to the domain).

We acquired a new server hardware with Windows 2008 R2, joined to same domain, and promoted it and made it the DNS server.

Syncing Offline Files on Windows XP is still working perfectly; however, the Windows 7 clients are facing CSC service crashes. The moment Sync Center starts syncing, multiple services crash at the same time. Offline files then become "enabled but not active".

Looking at Event Viewer, we can find the following errors:

-------------------------------------

As an attempt to sort this problem we tried several options few of which are:

1. flushing DNS on clients

2. Updating network drivers

3. sfc /scannow

4. Virus and malware scan

5. Rejoin the computer to domain

6. Resetting offline files cache

7. Clean boot

Notes: users can go the shared folders and browse their content.

What is really causing the problem!?
Thank you

Do you think that Wireshark might show something? Could it be the way packets are being sent over the network? Just a thought.
