Win2K resetting connections. Is there a service pack?

[Richard Sharpe]

Hi,

I just ran into a problem with a Win2K machine where if multiple 
connections occur on port 445, when the first one issues a NegProt, the 
rest get a reset.

It is compounded by the fact that the server does not want to accept 
sessions on port 139 (that is, the NetBIOS session requests are rejected).
 
Does anyone know if there is a service pack for the first problem?

Regards
