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.

Prove it by posting the correct answers. Then someone might help.

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?

I am a rookie at the computers and wanted to know what does it means when we say 16-bit windows or 32-bit windows or 32-bit x64 windows or IA64 version of windows. please anybody answer my question.

How many time are you going to ask the same question in one day?? It's rude, don't do it. This, like many other forum-based sites out there are an all-volunteer effort. Everybody answers whatever questions we can in the time that we have, so be patient.
By the way, this also reeks of a homework assignment...
16-bit Windows doesn't exist anymore. It refers to the VERY old Windows 3.x and below.
32-bit Windows starts with Windows 95 and Windows NT 3.x and proceeds through present day XP, Server 2003, and the upcomming Vista.
As for the rest, you can Google it yourself. Better yet, look it up on Wikipedia. You'll find stuff like this[^] on Windows XP x64.

If you know the answer, why you don't post this answer for his previous post? He ask again because he need the answer from this forum and his previous post do not have any person give him the answer. He should be blame when he post the question again when he already get the answer.

He didn't get an answer the first time because noone got around to answering him! Besides, this is stuff that is easily found on the 'Net with a couple of simple Googles.

If google could solve all the problem, so there is no need to have a code project forum to make people sharing an idea with each other

He did not force the other people to answer him. In his case he just need the answer to solve the problem that seem urgent for him but he didn't force the other people. STOP BLAME THE OTHER PEOPLE...

I blamed him for violating forum etiquett, which is not CodeProject specific. Reposting the same question again and again is rude, no matter what forum or newgroup your on.

Ok, I also see this post before but this post do not have any answer for him. So that is why he post it again and expect to get the answer for him.
Dave Kreskowiak wrote: I didn't say I did.
But in your previous post, you mention that you won't answer twice. It seem that you already give him the answer on the first post and he ask again. But on the first post, you didn't give him the answer. You blame him, then you give him the answer, this is not a good solution. If you know the answer why you didn't give him on the first post. Sometime people urgent at work or other issue and need the solution or advice to solve the problem, and post twice time, because he need the solution. Not force the other people to answer him. I also used to meet answer for people that post many time, but my solution is give the answer to the first post and the other post that have the same question, i will give a hyperlink for them to the post that I give the answer. That is enought. Do not need to blame the other people and make them upset.

I know that google could do that, but people are not the same. Sometime you thing is question is to simple for you but it is very hard for the other people that is the beginner. According to your background, I know that you have a lot of knowledge and experience in IT. But you should know that people are difference, that we classified a novice, professional, expert, guru... I blame you because i just want you to give a good solution for the other people. I didn't hate you or want you to move to another planet. We must have a good solidarity in order to support each other. Do you agree with me?  ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

He asked again in the same 24 hours. That's not enough time for us to get around to his question. It's plain rude, simple as that. You don't get to EXPECT an answer in a forum environment--especially one where you're not paying for the service! He has no right to expect an answer at all!

I didn't say I was blaming him for asking a simple question. I said he violated normal etiquette for posting the question twice. I did him a favor by partially answering his question, then showing him how to find the rest of the answers on his own. This skill alone is far more valuable than the answer to question itself.
You can go spoon feed someone all you want. But you're not really teaching them anything they need to know to survive the next question they've got.

Oh, for heavens sake! Put the poor sod out of his misery!
In Windows, this refers to the way memory is accessed.
16-bit applications access memory in 16-bit "chunks" (2-bytes). Most DOS and Windows 95 and 98 applications are 16-bit.
32-bit application access memory in 32-bit "chunks" (4-bytes).
64-bit application access memory in 64-bit "chunks" (8-bytes).
This means that an integer in 16-bit has a maximum value of 2^15 or 32,768, while the maximum value for an integer in 32-bit is 2^31 or 2,147,483,648, and so on.
Please note that you could have got all this information with Google.
Try it. Its a wonderful tool! Just do a search on "16-bit definition" and see what jumps out at you!!!!
