Scenario:
You have a domain controller running Windows Small Business Server 2003, and you have a domain joined Windows 7 Professional workstation. On this workstation is a user named Joe who uses a laptop and works remotely. Joe is the first at his company to have a Windows 7 computer that uses the Offline files feature. Joe cannot sync his files that are in his home network share. The following sync error appears: “The Process cannot access the file because it is being used by another process”
Problem:
Every single file in the home share receives a sync error. When the user is disconnected from the network none of the files are available offline.
Solution:
This problem requires you to make changes to the registry of the server. Use caution when editing registry values!
Ensure that the files aren’t infact being locked by a document management software suite or a security software. Popular computers featuring this typ of software are Dell and HP lap tops.
Offline Files in Windows 7 require Oplock to improve performance. Since Windows 7 uses SMB2.0 and Server 2003 uses SMB1 this error will occur simply because of oplocks being disabled.
On the Windows Small Business 2003 Server:
- Open up Registry editor by hitting Windows+R key and typing regedit followed by enter.
- In the left hand side browse to the following key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MRXSmb\Parameters.
- Create a DWORD value named OplocksDisabled and set it to 0 (Not disabled).
- On the left hand side browse to the following key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters.
- Change the following DWORD value EnableOplocks to 1 (Enabled).
