Hi,
as I've said in my post, there are multiple users that access simultaneously 
to this mdb, and the directory in wich is contained has 777 permission 
because all should modify this file or, to be more precise, everyone should 
modify the LDB file that is created/modify every time someone access to mdb.

All my clients XP are configured NOT to request oplocks.
Here you are the registry that I load in the clients:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters]
"EnableOplocks"=dword:00000000
"MinLinkThroughput"=dword:00000000
"MaxLinkDelay"=dword:0000003c
; "OplockBreakWait"=dword:00000080

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanworkstation\parameters]
"UseOpportunisticLocking"=dword:00000000

Thanks.
