>>I'm using Win '95. For my new system I may go with Win '98. I'm apprehensive about NT in case of a "blue window of death".<< I have a couple of NT machines and have never experienced "the blue screen of death" I have experienced "the black screen of death" in Win95! I use mostly DOS and Win95 but only because of the applications I use. I would trend toward NT if I wanted a stable network environment with multitasking. If one trading machine in a group will carry some load for the other machines I would consider two processors and extra RAM. A fast Internet connection will make a significant difference to your CPU load. News and realtime charts and quotes coming in at 10Mbs? If all of you programs and hardware is NT compatible I would think that NT would be a more stable environment. Initial setup may be more difficult. When you experience program crashes in NT they shouldn't take down your system as they might in Win95. If you are making a living trading I would think you would want a restoration plan for either Operating System and all installed software/files. Some type of complete backup. A second harddrive ready to plug in or the RAID system Networm talks about. I still do not quite understand how the RAID backup works when it comes time to restore. Hope I am not rocking your boat, just some thoughts. Zeuspaul

>>Is the speed of the internet connection cut in half cause you're using two ip's off one data feed?<< I had a long winded answer to your question but then I realized I didn't know what you meant by "using two ip's off one data feed". Hence what do you mean by "using two ip's off one data feed"? With out knowing more about what you mean by "ip" I say no. Because the speed of your internet connection will be limited by the speed of your data source's connection to the internet. The majority of data vendors run at a speed of T1 or less. As T1 is approximately 1.25 megabits per second and this is less than the rated speed of the internet connection at your end connecting to two or three data sources at one time will not slow down the speed of your internet connection.

Wingate/Winproxy: Is the software installed on both compters? Wingate is only installed on one computer, the one which has access to your internet provider. Can either computer access the net while the other is not running? Well, because you share one connection the computer which is physically connected to the net (your wingate machine) must be always up and running. If this computer is down you cannot access the net via clients. However, it doenst matter whether the clients are running or not. How long did it take you to install and configure Wingate? In the meantime it takes..hmm.. lets say 30 minutes or so. But at the very beginning it took me days (at that time i was not so familiar with tcp/ip networking as well). BTW i'm still not an expert. I'm concerned whether two different Castle Kill Key accounts can be ran using NAT. I guess if one is working with the nonregistered IP address (via wingate/winproxy set-up), it will work. An important point is that to the outside world (the servers you are connecting to) your computer appears only as if it has one IP address. (the registered one). Your own LAN is shielded to the net via Wingate or any other NAT program. That's one advantage of NAT, it is like a Firewall. Wrt Kill Key you may ask Castle whether it works behind a Firewall. If no, it won't run behind Wingate as well. If yes, it should. But as i said earlier, in case that it doesn't work on a client machine, you can always run Kill Key on the computer which has direct access to the net. This direct connection capability isn't lost even while wingate is running. So you dont have to care about it. No need to stop and start the Wingate service. Once set up properly you can forget about the Wingate process running in the back ground. 2 different Kill Key accounts ? Its not clear to me what you are planning to do. You want to trade with 2 different accounts at the same time, on 2 different computers? If this is the case, sure you must check first whether Kill Key works behind Wingate. Once it works, you dont have to care about IP adresses and the NAT thing. I'm still concerned about any slow downs. If the software has to do any interpretations between IP address, doesn't this take time? sure the 'adress translation' takes some time. Each transmitted/received package header must be modified. But the operations required are very simple. Personally, i'm not aware of any significant slow down using my ISDN 64k connection. Is the speed of the internet connection cut in half cause you're using two ip's off one data feed? well, the speed of your conection is always the same, but, it is shared among 2 computers. So you cant get the max bandwidth for each computer. The question is whow much do you get. My experience is, it seems to be better to download things in paralell at the same time. I just made a test: I downloaded a matrox driver from matrox ftp site: using my wingate machine i got a transfer rate of 7.2K/sec. On my second computer (behind wingate) same speed. Now, using both computers a the same time (downloading 2 different files) i got 3.5K/Sec for the wingate computer and 3.8K/sec for my client machine.
