Stop iMac from seeing Windows machines on wireless network

Here's a conundrum!
Brand new iMacs from 10.5.8 - all see Windows XP machines in the shared panel on the finder windows. We need to turn this off as the new macs are on a school network. They need to be on the wireless for internet, but they can't see the office machines for obvious reasons. The sharing is turned off on the Macs and Bonjour is disabled on the windows machines so why can we still see and access the windows computers. Can anyone tell me how to stop our macs seeing the windows machines. The
windows machines still need to be on the network btw as the office needs to have the two windows machines connected to each other. The macs dont need to see any computers so how do i turn it off.

Our solution was to have a separate students' network with its own wireless hubs.
In our school we have a server configured to keep the office and the students' networks separate.
We then have wireless hubs for students and wireless hubs for staff.
In this way the computers are not on the same network, and this should also make it more difficult.
for students to hack into admin computers.
You should be thankful that this iMac made you realized how vulnerable your networked XP computers actually are, and that, at this point, they are still visible to hackers.

I am trying to import Firefox bookmarks from a Windows machine into Firefox on an Apple. I do not want to use Safari. How do I do this?

am trying to import Firefox bookmarks from a Windows machine into Firefox on an Apple. I do not want to use Safari. How do I do this?
I have, on my HP laptop, running XP Pro, using Firefox 4.0, went under bookmarks to show all bookmarks. A window opens up that says library. I then go to import and back up, and I choose export HTML. I then move this file over to my new Mac Pro. On my Mac Pro I also have Firefox 4.0. I go up under bookmarks, show all bookmarks, import HTML. It lets me browse and I find the file on the desktop, I select it then nothing happens. I am not interested in using Safari. I would like to continue using Firefox. However, as an experiment, I followed the same process except on my Apple computer I opened up Safari and tried to import in the Firefox bookmarks. It came up with an error saying the file could not be accessed. I then thought perhaps the file got corrupted, so I went back to my Windows Firefox and re-exported the bookmarks again. Same problem. So, am I creating the bookmarks incorrectly on my Windows machine?
Thanks,
Kent

Probably your Mac cannot understand the Windows html format, please try the following to see if it helps:
In your PC, export the bookmarks in html as you did in your post. After you have saved it, change the name of the file to “bookmarks.html” and save it again.
In your Mac, import the saved file as you posted.

DB performance is very slow from a WINDOWS machine

Hi,
We have written an application which contains a pkg that will write all the logs related to application in the form of a text file. We are using utl file operation to achieve the same. As of now I have 2 Setups. We have two IBM servers with similar configuration, one in which we have installed Windows server 2003 and the other with HP-UX. We have installed 11g version of DB In these two machines. The problem is with the performance of the application. The DB in Unix server takes less time for writing the log. For eg: it takes 10 secs to write 5MB log. But the same takes more than an hour from a Windows machine. I want to know whether the performance of the DB depends on the OS which we are operating from or else it depends on the parameters set for the DB? Kindly help me.
Thanks

Kindly help me.I did some testing a while back between windows and linux and the difference on properly configured windows and linux database servers (same hardware same db version) wasn't worth talking about (< 10% often less than 5%).
That said it's not clear what exactly you mean. If you mean that writing a 5mb file on a windows machine takes an hour, then yep something is badly wrong - most likely with the hardware. I suspect though that what you mean is that you do a bunch of database work and that takes an hour on one machine and 10s on the other. This is likely to be a problem amenable to response time analysis, that is to say talking your workload and tracing it with timing information to see where it is spending the time. As you say it is your package, you will also be able to (and should) instrument your own code to see where the time is spent.
given the huge difference, you may well also find that statspack/awr will spit out your offending processes quite well as well.

Can't see Windows machines in Finder/Shared

I have upgraded to 10.5.2 and can't see Windows machines on my local network in the shared panel of finder. I can connect to the machines using their IP address in using the Go to server command and the IP address then shows in the finder. I want the windows machines to show by their name, automatically, in the finder pane as they should.
All machines on the network have assigned ip addresses by in the router.

Hello
In the DNS settings of your router there should be two options:
1. DNS server set by ISP
2. Enter DNS server manually
If you have set option 2 and you use a service such as Open DNS or if you have 1 and your ISP offers a rubbish DNS server when you try to connect from finder the DNS server tries to resolve the name of the machine gives you a wrong IP address and after a long time waiting you get a connection error.
Solution:
1. Try to eliminate open dns and use the ISP dynamically set DNS server
2. If 1 still gives a problem (your ISP DNS is rubbish) and you have assigned static IP to your machines follow those instructions:
a. Enter as administrator in each MAC OS X 10.5 machine and open the terminal
b. enter the following command at the prompt: sudo pico /etc/hosts
c. insert an entry for each of your other computers followed by the computer name
d. save the file and reboot the machine
e. You should now see the other computers on the finder bar and be able to connect using SMB://SERVERNAME provided all computers are in the same workgroup
f. repeat the process for the other MAC OS X 10.5 machines

Downloding DMG files from a Windows machine

Hi
Anyone know how I can download the DMG installations files if I'm accessing the site from a Windows machine? When I try to download a trial version, it attempts to download an exe file which as I understand it, won't work on the Mac. I am planning to download the files and install on another machine (Mac) which is isolated from the internet.
Thanks
Alessandro

Thanks for pointing me to that useful-looking guide. I'll have to go through it and see if I've followed the correct steps.
But, yes I'm using XP Professional and I know I've done this before. I had to re-install some Windows components on the Dell, and that's when I lost access and had to start over. I guess I should have kept notes from last time.
BTW... I just installed Leopard on one of my Macs and can't access the Dell at all from there... including the external F-drive that was no problem before. I suppose I should locate a Leopard forum for that, but if anything comes to mind, please let me know.

Windows machine on local network can see all volumes mounted on my MBP

I have a Macbook Pro running 10.6.4 with 4 volumes mounted (Macintosh HD, Scratch Drive, Files, & Media). On this same network I have a Windows 7 machine. I just noticed today that in the Windows File Explorer I can see all 4 of the volumes that I have mounted on my Mac. Not only can I see the volumes, I can drill down into folders on my Mac, open files, and even make changes to and save those files.
I've checked all the Sharing options on my Mac and everything is turned off and my firewall is turned on. I know that in the past I wasn't able to see these volumes from the Windows machine. I recently upgraded to 10.6.4 but don't know if that has anything to do with this as I rarely do anything with that Windows machine so I'm not really sure when this started.
Any advice would be greatly appreciated.
Cheers!

Check this
Go to system preferences--------->
Sharing -------------->
File Sharing ---------------> ( you said this is not selected )
then
go to the options ------------->
and See if SMB sharing on or not .
this is the only place which is sharing with windows .......
hope it helps

Upgrading my work PC is NOT an option, but I'd like my Mac to be able to recognise the attachment for what it is
Let see, you are using a proprietary file format that is only supposed to work with Outlook. It doesn't work for millions of Windows or Mac or Linux email users that depend on other email programs like Outlook Express, Thunderbird, Apple Mail, webmail, etc.
Microsoft has had to publish instructions so that their program's users can make themselves compatible with the rest of the world.
http://support.microsoft.com/kb/290809
You are causing your own problem by not making a simple change in your program's options. Changes in the Outlook preferences can be made either Globally or by the Recipient.
Follow these steps in Outlook 2007 to turn off TNEF:
1. On the Tools menu, click Options.
2. Click the Mail Format tab.
3. In the Compose in this message format box, click Plain Text or HTML, and then click OK.
Don't know of a better way to fix this problem for everyone concerned. Even if you get the fix to work with your machine, you will not enable all of the people receiving your emails to be able to work with you. That's a losing battle that's been caused by Microsoft.
Now if Microsoft created a Mail plugin for other email programs like they do for their video format's and services (flip4mac, Office Live Plugin, etc), then I would consider using their email program to deal with my clients. Until then, I need to be compatible with many different programs in other countries, on different platforms. Maybe that's going to change when they bring out the new Office 2011 with Outlook for the Mac...

I brought my itunes library onto a mac from a windows machine and now i have two separate libraries. How can I merge them?

I moved to Mac from a Windows machine where I had downloaded all of my CDs into iTunes. When I got my Mac it only put my purchased items into my library. So I merged my windows library and it created a whole new user account with that on it. I now have two libraries and can only sync music with one account or I lose all of my imported CDs. Help! How do I merge them.

The easiest way is to get both computers on your home network and copy the files over the network. It's easier than you think
Check this earlier thread:
[How do I move my itunes library to new computer|http://discussions.apple.com/thread.jspa?messageID=7937172&#7937172]
That thread mentions Target Disk Mode, which won't help moving from a PC to a Mac. But you can use file sharing to copy the files.
As the articles all say: don't forget to de-authorize your PC before you get rid of it.

How do I stop iMac from going to sleep automatically after 15minutes of inactivity

How do I stop imac from shutting down automatically after 15minutes of inactivity, trying to play music but the imac keeps going to sleep, tried changing power saving preferences to never shut down, never go to sleep, unticked put the hard disks to sleep, automatically reduce brightness, but still goes to sleep.

Try a PRAM/NVRAM reset.
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
After resetting NVRAM or PRAM, you may need to reconfigure your settings for speaker volume, screen resolution, startup disk selection, and time zone information. If issues persist, your Mac's logic board battery may need to be replaced. The logic board battery helps retain NVRAM/PRAM settings when your computer is shut down. You can take your Mac to a Mac Genius or Apple Authorized Service Provider to replace the battery on the logic board.

How do i combine iTunes libraries ? from old Windows machine to my Mac?

Hi there...I have an expiring Windows machine where my kids first sync'd their iPods....That machine is dying and i want to bring those songs (hundreds!) to my Mac computer....But I already have lots of music on my Mac....every time my kids have tried connecting their iPods to the Mac it tells them that it will erase their music and install the music I have on the Mac....So...is there a way for me to add the music from the Windows machine to my Mac library? Or...since they each have an account on the Mac...can each account have its own iTunes where they could bring in their music? that way they could at least save the songs they have in their iPods. i know the music will not be transferred from the iPod to the Mac but I have backup diskettes I made on the windows machine. Can i use those? I am hoping I do not lose all that music ($$$)

Click here and follow the instructions.

How do I delete itunes library and move library from old windows machine to

My daughter bought a new macbook and would like to move her itunes library from the windows machine to the mac. I copied it to the mac and moved the existing itunes folder to the trash. By the way, she got 3 free downloads from Apple and they were in the library I moved to the trash bin. I then moved the backup folder to the location of the itunes folder I had deleted. When I open itunes, it sees the 3 songs in the deleted folder. How do I get itunes to recognoze the new itunes folder?

Thank you. As I understand it, if the original iTunes folder had never been populated, we would have been able to move the library exported from Windows into iTunes and preserve the playlists. Because my daughter downloaded 3 songs she does not even like, we have no way of preserving playlists? There must be some way to remove all connections to the first library. Is it possible remove the iTunes application and then either re-install it from the original disks or else download it. I know you can download iTunes for Windows, not sure if it is there for Macs. My guess is that if she starts itunes from scratch, there would be no references to the intial DB and we could then move in the folder from Windows without a problem.

Downloading Updates from a Window Machine

Apple is quite helpful in checking the machine from which you are attempting a download, however, for those of us on dialup at home, we come to work where a fast connection exists, usually through a windows machine. Attempting to download and save an update takes us to a windows only option, only (XP or Vista options).
There used to be a 'mac' button at the bottom of the page which is now gone. Pretty irritating. Unless the update is a mac-only application, you are pretty much out of luck.
Any ideas on how to obtain a mac download on a windows machine???

Thanks for the reply. Attempting to download from the Apple site. Even did a search for Safari 3.1.2 mac, came upon part of the apple site actually discussing the version for tiger. Clicked on it and it took me to the windows version.
That is exactly what I do (download to a flash drive and install at home). Problem is that when there is a windows version and a mac version, the windows version (from a windows machine) is the ONLY option for download presented. Downloading a mac-only version (Security updates and so on) is no problem. Saved to flash drive and installed with no problems.
In times past, there was a small link posted to the download page giving the option to go to the mac version. That link has now disappeared, and you are left with either downloading a windows version, no download, or downloading an 80MB file on dialup.
If apple would re-install the mac version option, that would solve my problem.

I have recently changed to an iMac from a Windows PC. How do I delete files and format the memory card in my helmet cam?

I have recently changed to an iMac from a Windows PC. How do I delete files and reformat the memory card in my helmetcam?

If you return the memory card to the helmetcam, it may choose to reformat it before use; back to some FAT-16 or FAT-32 format many of these third-party cards and cameras use. Unless you were going to use it for Mac OS X and format it with HFS+ or in a partition map for Mac data, etc.
If not, the easiest way to reformat the card may have been in the camera itself. I've formatted several kinds of camera cards, drives, USB flash drive, and others. The means varies with the intended purpose. Sometimes the default is the best; since it is platform neutral if the device is seen by both players.
Good luck & happy computing!

In migrating to a 21.3" iMac from a Time Machine backup, can I do this more than once?

In migrating to a 21.3" iMac from a Time Machine backup, can I do this more than once?

David,
My apologies....I was working on questions from a different thread and thought yours was part of that one. Your question is fine where it is....
Now....that being said, I'm afraid I don't know the answer to your question. I know you can exclude certain items from being backed up in Time Machine, which would save disk space on your external drive. But, you'd first have to calculate how much disk space you're using for the different things you want to back up vs. those you want to exclude.
I think it MIGHT be possible to do what you want, but (in my honest opinion) it's a recipe for a LOT of headaches should things not work out as you calculated. Better (again, in my opinion) to just pick up a larger external hard drive and transfer everything as Time Machine was designed.
Just my $0.02 worth.

on Game Center how do you stop players from seeing the last time you have played a game? Or the last time you signed in.

hello, this should be addressed in a later version of firefox. as a workaround in the meanwhile you could try this: enter '''about:config''' into the firefox location bar (confirm the info message in case it shows up) & search for the preference named '''browser.sessionstore.resume_from_crash'''. double-click it and change its value to '''false'''.
