In fact, you can't really know the ip is really from a public ip or connect behind NAT since you should not know any private IP behind NAT. However, I found that MSN PLUS can detect show both the public and private IP of the user. I don't know why it can do it as well. I can just guess MSN PLUS may know the algoithm of traslation IP in router so that it can show the private IP.

MSN Plus can show it because that information is in the headers of the HTTP request and IP packets used to send them. The information he's looking for is built up during the transfer of the packets down the network. It is NOT all put into the packets before they leave the client machine, only some of it is. The network itself puts the rest of the information in.

any idea guys ??? my system is running slow and gives an error that says that the system is running low on virtual memory. How do i increase it?? Please!!

1) Add more physical memory (preferred)
2) Increase the size of your page files
Windows will by default expand page files for you.
If you're seeing the popup frequently, reduce the amount of software you're running at one time. If you're not running much there's probably a memory leak somewhere.

I need to look at the HTTP packets for GET and POST transmitals to a web server, from a browser (IE, etc), in the case where a User is cliking on the SUBMIT button within a web page that has a Form on it.
We can use any browser, if that makes the job easier.
Any help would be much appreciated.
Thanks,
Robert

Fiddler[^] is written by a member of the IE team. It acts as a proxy between the client and server.
If you don't want to use a proxy, then you'll have to use some kind of network traffic analyzer. I use Ethereal[^].

So, I have written a service which never made any problems, but it just doesn't want to run under WinXP 64bit (the same service runs w/o any problems under 32bit). The event log always says something about an invalid parameter (event id 7023). It seems that the service starts during boot, but stops at some point; I can't test this myself, since I don't have a 64bit system - my users are just reporting this.
What could the cause for this be? I really don't understand why it works on a 32bit XP system, but fails on a 64bit one.

I finally talked the boss into buying us a plotter - an HP DesignJet 800 with built in network print controller. It's all assembled and connected to the network, but for one thing. It doesn't work. I've reinstalled it multiple times, trying to use the installer from my workstation, but the thing insists on assigning itself an IP address that is already in use on the network! The installer allows the option to assign an IP address manually, but it doesn't work - the automatically chosen address sticks and cannot be overridden.
I know that, in the past, the HP JetDirect system has been an unreliable nightmare for admins, but I thought that had been resolved. Can anyone suggest a way to make this thing work correctly?

Check the manual or manufacturer website if there is any knowledge base (KB) relate to your plotter.

It's still a nightmare to configure these things! 
In the past, I've sometimes found it necessary to create a local network with just a PC and the JetDirect connected to each other to get the config straighted out using JetAdmin. Disable everything you're not using, like AppleTalk, DLC and IPX. Disable the Config options you're not using, like EWS Config, Telnet Config and SLP Config.

I had to do a bit of jiggering, but I finally got the front panel to respond and let me into the configuration menu. I've got it set up as a standalone network device, with the drivers installed on individual PCs using network ports. I must say, it's a very nice printer, now that it works!

It sounds like it. I haven't played with a large-format printer/plotter in quite a long time.

This is not my homework.I know the final answers, because they are
behind the questions , but I don't know why?
I examined many books, but had not found the solution.

Believe me! We know what homework looks like. Especially when you copy-and-paste it word-for-word!

You didn't mention any of this in your original post. The only place you didn't look is the book your using in your class. If you looked there and couldn't find the answer, you're other best option is to ask the prof teaching the class.

My major isn't computer and I study computer in myself.It is difficult to find a teacher to ask.
I thought I can find solution in good time for posting the questions,but I don't think so now.
Why don't believe me ? Are American students often lie?
