samba - Feb 2008 - XP to samba = ok samba to XP = NT_STATUS_INSUFF_SERVER_RESOURCES

In response to
<http://lists.samba.org/archive/samba/2003-October/000161.html>:

The problem is on the server side; it has nothing to do with Samba.  
The exact cause of this message 
should be logged in the System event log on the file server.

In my case it was too many network filters installed.
In this case, the recipe from Microsoft was 
to add a DWORD parameter named IrpStackSize 
to the LAN Manager Server registry key.  
The default value for this parameter is 15 if it is absent; 
set it to 15 and increase it by steps of 5 until the problem goes away.
Keep in mind that you have to restart the Server service 
each time you update the registry.
