NIDAQmx accesses internet

[I_B]

I've just upgraded to version 8.3 of NIDAQmx from version 7.4   The first function call to NIDAQmx (i.e. DAQmxCreateTask) causes Norton Internet Security to issue a warning that my application is attempting to connect to a DNS server.   This message is clearly triggered by the function call to NIDAQmx.   My questions are:

1) What is NIDAQmx doing to generate this message (i.e. why is NIDAQmx accessing the internet)?

2) Can I disable NIDAQmx so this behavior is halted and, if so, how do I disable this functionality in NIDAQmx?

Cheers,

Ian

In DAQmx 8.3 (actually MAX 4.1) we changed how we utilized our RPC server.  We used to connect via shared memory, but now we open up a local socket via TCP/IP to connect to the RPC server.  We need to be able to do this for a variety of reasons.  This is only local and we aren't trying to connect to the internet.  If you are really concerned you can download the sysinternal TCP utility which shows all of the open sockets and who has a hold of them.  One of the biggest reasons why this change was necessary is in preparation of Windows Vista.  I don't think you can really disable this functionality.  Let me know if this is unsatisfactory.
