I have CIFS running on an oes2 sp1 test server. It works fine with my xp client until I enable offline files. With offline files enabled I can create and delete files, but I am unable to modify them and often cannot open microsoft office documents (they give 'Access Denied.') or they just open read only. I see this multiple times in the log when trying to modify a file:

Jan 29 14:29:57 test-oes CIFS[12893]: WARNING: CODIR: Error 0
Jan 29 14:29:57 test-oes CIFS[12893]: ERROR: CODIR: LockDirCacheEntry failed
Jan 29 14:29:57 test-oes CIFS[12893]: ERROR: SMB: SMB_ntcreateandx exit, TID=18, error=1:5 nterror=12

The user has full access to the directory and it works fine over ncp or with offline files disabled.

Any thoughts?

Thanks,
Jeremiah
