You sound like in the same boat as me…I have that same similiar problems but I tried a regstery fix and it seems to have controlled the lockup or freeze problem so far here is the registery fix I used but before you do so make sure you backup your registery before doing this fix. But if it don’t work just delete it as it is a addin registery not a registery that will be modified.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters]
“SizeReqBuf”=dword:00004000

Try this and see if it work. The dword value is put in a decimal 16384.
