Opportunistic File Locks

[jameslearuk]

Hi there,

I have a Windows 2003 Enterprise File Server and am having issues with sending files via Connect6 Direct.

There are 8 folders that get written to. One folder is written to by an application that calls MS Word functions in the background and this is working fine. The other 7 folders are written to using MS Word directly off the same machine as the other application but I am seeing sporadic failures in Connect Direct that point to a sharing violation.

After using FILEMON I an seeing that these files are locked and after some investigation I am thinking that it is related to opportunistic file locking.

The clients are WinXP.

Having done some searching I found the following link -

http://support.microsoft.com/kb/q296264/

When I looked for the Registry keys mentioned, suck as HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MRXSmb\Parameters\OplocksDisabled I cannot find it.

If the key is not there, is there a default setting that either enables or disables it?

Can anyone offer some advice?

Regards

James

As a default it is enabled, even if the entry is not there.

add the EnableOplocks REG_DWORD, set it as 0 to disable it, as described in the KB. Personally I have only used this one entry, not the others as described in the KB.

Just check a Win2003 server, the entry is not there by default.
