When you get remote user calls the originating thread is a system thread

I mean, the current process is SYSTEM.Usually, although not always, when a local user request takes place, the
incomming thread does not
belong to system process, it is a user space thread.So you could use a simple (although unsafe) check to discriminate request
incomming from remote users by
means of checking current process when you receive a request. If it is
SYSTEM you may think it is comming
from a remote user.Please, note that I said ‘not always’. For example, request for local mapped
drives are received through SVR and
current process is SYSTEM. On the other hands, some fllters may hook calls
and generate
new requests from different threads…Inaki.
