Network cycle thief? (W2K)

[vynbal]

I am trying to write a graphics simulation to run on W2K, but have a problem. Something interrupts my thread on a quite regular basis - I lose 12.6 ms every 0.656 sec. I have tried turning off all the services I can turn off and terminating all of the tasks I can terminate and have set my own task to REALTIME priority and I am still being interrupted - but ONLY when connected to a network! If I remove the network cable or disable the card, then no interruptions.

Any clues?

Thanks

This should be in the Network forum.

My guess is that another computer/program on the network is accessing your computer and there may be no way to prevent it. Your own diagnostic tends to bear that out. Perhaps your network administrator may have some help for you.

You have also provided your own solution, disconnect from the network while working on your graphics simulation.

This happens even when the subject computer is the only node attached to the hub, so it is not some out there which is doing it, it is within its own box.

As to the "solution" alas, the simulation is a network based program, i.e. some other machine is actually running the sim and putting out network packets updating the graphics on how to draw, so disconnecting from the network is not a solution.

I missed the part about the computer requirement to be connected to the network to run the simulation, got the impression it would run stand-alone/no network connection.

Any time 2 or more computers are connected by whatever means, they will be 'talking' back and forth, mine do frequently. Turning off one of the transmissions may be the key but finding which will be a large undertaking.
