I'm seeing other computers "in the network"

Hi, all.
I am seeing other computers, I assume picked up by the wireless internet connection, or something.
I wonder if they can "see" mine in theirs?? I'm quite concerned by this
If so, how do I "block" that, so that my computer doesn't show up in other people's networks. I don't want to "share" folders, or anything.
Thanx !

Look in the Airport (or wireless router) preferences: you should be able to create a 'closed' network, i.e. one which doesn't broadcast its name and thus doesn't show up in the lists of networks on other computers. You should also set a WPA encryption and a safe password: and you can restrict access to your network to computers with specific MAC addresses (this is the address of the wireless card, nothing to do with Macintosh). Asa already said, you have to have File Sharing turned on before anyone can get into your computer (and they would need the account password).
This essay may perhaps help a bit:

We have a PC with iTunes that needs the hard drive reformatted. Right now, it can't connect to other computers on the network. Can I save my music to a thumb drive, then re-load when the computer is reformatted?

We have a Windows XP desktop with iTunes for windows. The hard drive needs to be reformatted. Right now, the computer will not connect to other computers on the network. Can I save my iTunes songs to a thumbdrive, then re-load after reformatting? How do I do it?

Copy the entire iTunes folder out to the drive. If it is too big to go as one copy stuff over to another computer in batches. It is important to have not only the media but the library file in order to properly restore your library.
See also this User Tip. Assuming the machine won't connect to the internet you could download the SyncToy installer on another machine and then transfer it with the thumb drive. If it will connect to the net don't forget to deauthorize the machine before reformatting the hard drive.

Connecting to other computers on the network

I just replaced an older Belkin wireless router with the new Airport extreme. I like it very much but I cannot now figure out how to connect to other computers on the network. With the old router I just clicked on network in the finder window and all the other computers on the network showed up an dI could click on one to connect. Now I see notheng. Any ideas????

I'm getting the same problem. I used to have the snow AEBS, but about 2 weeks ago I got the new one. Never had a problem connecting to my other macs in the house through network in the finder... now, no other machines show up.
Because there's no communication or recognition of devices through AEBS, wireless printing goes out the door too. My printer is plugged in by ethernet to my house network. If I am connected by ethernet to my network, I can print, but if it's wireless, nope.
Today, I got the apple tv. I was super excited unboxing it, hooking it up... and then when I go to sync up through itunes... oh wait, it doesn't show up in the devices list because of my AEBS problem.
Anyone have any ideas? I would love to play around with apple tv so please help... thanks.

My G5 can't locate other computers on the network

It's weird it can find the internet and networked printers but NO other computers at all. Furthermore other computers on the network have no problem finding each other or this specific computer.
Any ideas?
There are both macs, windows, and a linux based NAS on this network.

It most certainly does explain why one wouldn't be able to see others, if it's not configured as part of a workgroup or the automounter isn't running, this single machine will not be able to mount on demand, those shares which are advertised on other hosts.
Macs are not complicated and as I see by your signon, you know something of a root account. I would think you'd feel right at home on a mac under it's covers I myself have been a real Unix sysadmin for 18 years and played on all types of enterprise hardware, believe me, Macs are easy to fiddle with. Most of the time, when someone can't see other machines using the network browser,it's because some tool disabled NFS. Check your /etc/hostconfig for the automounter line and also check in the /Library/StartupItems and make sure NFS gets hit when the box starts.
I know if I kill my automounter, all the network mounting stops.

I see other computers on my network. I just cannot connect to one of them.

Apologies if this has been covered. my 2009 Macbook pro can see all of the other 3 computers on the home network. It can also see the time capsule. However, It can only connect to the time capsule and 2 of the other computers.
The same is true for a imac G5 that i have on the network as well. It can only connect to the time capsule. i get a message that "connection failed" after about 45 seconds
The g5 can connect to 2 of the other computers. Why can the g5 and the MBP not connect to each other?
Any thing i am not thinking of?

I am no expert, but per my recent post, I have been working through file sharing issues for the first time. I too have a MacBook and G5.
On my G5 I went to System Preferences --> Sharing --> File Sharing and added the drives (using the "+" icon) to the "Shared Folders" section. I have multiple drives and made sure that each one had read and write privileges. My MacBook can see them all.
I may be missing some other settings that would be beneficial, so I will be watching this thread with interest. Specifically, I have been wondering if setting up another user account on the G5 would help with overall file sharing functionality/options as well as MacBook Time Machine backups.

VMWare Fusion - Cannot see other computers in the Workgroup

For some reason I'm unable to see or access other machines in my Windows Workgroup from within Fusion 1.1.3. Alternatively, I cannot see or access the VM from other WinXP machines in my workgroup. The other WinXP machines in my workgroup CAN at least ping the VM. I cannot ping anything outside of the VM other than OS X and my gateway/router. And yes, I've tried disabling the firewall on both the VM and other Windows machines in my Workgroupto no avail.
I am currently using a Bridged network configuration in Fusion. If I open an explorer window in the VM and type in the UNC path to OS X I can access it, but not other Windows machines on my network... why?
Perhaps someone can at least confirm whether they can access/see other computers in their Workgroup from Fusion?
Maybe this simply isn't possible under Fusion and I'm just going around in circles here...
Thanks

How did you resolve this? I am about ready to toss my month-old macbook out the window over this.

New Router- Internet OK, but cannot see other machines on the network with Windows Explorer

Everything was fine (but slow) with my old Linksys BRFW1154. Ordered and got a new WRT350N. Multiple computers (using Windows XP) on network can all access the internet and the network printer, but when I try to use Windows Explorer to see files etc on other computers (in My Network Places) from any computer, I no longer can see the other computers. I get the error: "Workgroup is not accessible. You might not have permission to use this ........etc....".
Any ideas out there as to how I get my network working again?

check whether all the computers can ping each other fine...also, the computers should be in the same workgroup

Cannot see other PCs on the network

I'm using Leopard 10.5.6 on the new Macbook connected to the internet via Belkin router. the problem is I cannot see the other machines on the network which normally can be seen when i was using a PC.
I've already turned my SMB in System Pref/Sharing
additional information, sometimes, i was able to but see sometimes i wasn't, depends on my luck.
router ip 192.168.2.1
target PC 192.168.2.2
pls help.
thanks in advance and sorry for my bad English

Welcome to Apple Discussions:

That won't do anything. That only allows sharing From Mac To PC.

Maverick says Luck has nothing to do with it
router ip 192.168.2.1
target PC 192.168.2.2
Can you ping the PC? That's the first step. In other words, can you see it on the most basic level?
Open a terminal and enter
ping 192.168.2.2
if that's the PC in question.
If you get a non-null response you are half-way there.
On the PCs, be sure you have file sharing turned on and also be sure you choose simple file sharing.
On the Mac, in the Finder Go menu, enter the IP of the PC where it says "Connect to Server" and you should get a login window. Enter the user id and password for an existing account on the PC.
That usually takes care of it.
pls help.
thanks in advance and sorry for my bad English

Since upgrading to Lion i can no longer see other computers in my network and vice versa. What has gone on?

As the title suggests! I can no longer see any of the computers in my network, Mac or otherwise.
I have checked sharing permissions on all required computers and all seems to be good and have disabled firewalls.
I notice a few people have had similar problems with screen sharing but I am not even seeing another station to pottentialy share a screen with!
MBP 2.4GHz Intel Core 2 Duo

Windows 7 does not see other computers in My Network Places

Hi all,
I have a weird issue with a behavior of Windows 7 machines. The setup is as following: domain with WinSrv 2008R2 DC-s, functional level of the domain is WinSrv2008R2, there are Windows XP and WIndows 7 machines on the network. Users use My Network places
to access shares on other people-s PC's. Everything was fine while we had WinSrv2003 domain controller. After it was upgraded to WinSrv2008R2, Windows 7 machined cannot see all of the computers in My network places. To make things even worse, there are no
rules - some Win 7 machines see others just fine, some see 30 PC's (out of 100), some see all after doing a refresh...all sorts of different situations. I have no idea where else to look. Can it be some DNS setting that I missing? Any help is much appreciated

Hi Dino,
As I known, by default computer browser service is not started in windows 2008 server and higher OS.
You should enable NetBios over TCP/IP on the NCI settings and start the browser service in the services.msc and it should show you all the list of computers connected on
network.
we should enable Network Discovery in the Network and Sharing Center first.
Please also temporarily turn off firewall on each machine.
In addition, please modify relevant settings on Windows 7 machine.
a. Click Start and open Control Panel.
b. Open "Network and Sharing Center" and click "Advanced sharing settings".
c. Expand the current network profile (such as "Home or Work"), and then select the following options:
"Turn on Network Discovery",
"Turn on file and printer sharing",
"Turn on sharing so anyone with network access can read and write files in the Public folders",
"Turn off password protected sharing"
If the issue persists, try to access another computer by entering
\\computername in the Start Search box. Let us know if it works properly.
For a test, you may also disable IPv6 in adapter properties.
a. Click the Start Button, type "devmgmt.msc" (without quotation marks) in the Start Search box and press Enter.
b. Double click to expand "Network Adaptors".
c. Right click your network card and click Properties.
d. Click Advance tab. High light Speed & Duplex
e. If you would like to use the full functionality, please set the Value to the highest Full.
f. Click OK.
Hope it helps.

Can't find other computers on the network

Ok, so I have a wrt54g wireless router thats directly connected to my main desktop pc. I have another pc and a laptop that's set up wireless. I'd like to link them to the main desktop so I can access files and the printer. I can't seem to figure it out. Does anyone on here know the steps I need to go through to do this? The only problem I might have is that the 2 desktops are running xp pro while the laptop is Vista home basic. Any help would be great!!!

Sharing my iTunes library with other computers on the network

Hi Everybody,
I have an external hard disk with about 125 gigs of music on it, and I've spent a year going through it and categorizing it, and rating the songs. The hard disk is plugged into my Aiport Extreme, and communicates with my iMac just fine. My plan was to use my old windows laptop w/ iTunes, plug it into my stereo in the other room and have it pull music off the hd through the Airport, so I could have a jukebox for my stereo.
I have the windows machine communicating with the Airport and hd, so I have access to the music. I thought I might be able to get the library information if I Exported the Library to the external hd, but it did't work. Next I Exported my playlist from the Mac's iTunes, and Imported it on to the pc's. This shows my playlists, but they are all empty and there is no My Rating information.
What I would love it to do would be to have mirror playlist information on each computer, and any changes in the playlist would automatically get updated on the other computer's iTunes. for this I would think you would need your Library information at the source of the music, so on the external hard disk, and it would be shared by each computer. It'd be great if all the album covers did this too. I really don't want to have to go through all that music again on the pc, and would probably just use my iPod with my stereo if this is not possible. Any suggestions?
Forgive me if this has been written about already. Seems like someone else would have run into this too, but I couldn't find any searching through the discussions.
Thanks, -Victor

Move the entire _iTunes folder_ located in *My Documents/My Music*/ to a Shared directory. Make sure to set this folder for read/write permissions for all users.
I set my permissions as follows OS 10.4.X:
first under the original owners login, change all permissions to read & write, then change 'group' to wheel. Then change the owner from the user to system (I applied to all within ~ may not be necessary).
Start iTunes holding the Shift key and select *Choose existing library* then pick the iTunes library file you moved into the Shared directory.
In iTunes 7.5, you'll need to hold the Option key and then pick the /Users/Shared/iTunes/iTunes Music
Quit iTunes and log out of your user and let her log in.
Start iTunes holding the Shift key and select *Choose existing library* then pick the iTunes library file you moved into the Shared directory.
Now she needs to File -> *Add folder to library* and pick *My Documents*/My Music*/*iTunes*/iTunes music*.
This will add all her music to the common library.
Once this is complete, she can delete *My Documents*/My Music*/*iTunes.
Do this for all users. Any changes made by one will be seen by all.

Can't see other computers on network through wireless/wired OK

Our wireless clients that connect through our AP541N cannot see other computers on the network. They can ping other computers by IP and host name and access the internet OK. Mapped network drives can be connected initially but are very unreliable and always end up disconnecting. Restarting the computer does not help. When these computers are wired they see the network as expected. Does anyone know why my wireless network would behave differently then the wired? The wired and wireless networks are on the same VLAN. The wireless clients are all Windows 7 systems. Thanks.

Hi Andy,
Thank you for posting. Go to Wireless Network Setup (VAPs) and see if Station Isolation is enabled for the SSID in question. From the Help menu:
When Station Isolation is disabled, wireless clients can communicate with one another normally by sending traffic through the AP.
When Station Isolation is enabled, the AP blocks communication between wireless clients on the same VAP. The AP still allows data traffic between its wireless clients and wired devices on the network, across a WDS link, and with other wireless clients associated with a different VAP.

Can't 'see" other computers on my home network

I just added a third Mac to my home network. We already had a G4 running OSX.2 and an iBook running OSX.4. I've now added a G4 running OSX.4, but the new computer doesn't "see" the other computers in the network list.
On the first G4, if I browse the network (by pressing apple-K) I see the other two computers, the iBook and the new G4.
On the iBook, if I open a finder window and click the "Network" icon, I get the other two computers listed.
But on the new G4, if I open a finder window and select the Network icon, I get three folders, "Applications", "Library", and "Users". And these three folders are apparently empty.
I DO have internet connection, so the connection is okay. And if I press apple-K to get a server list, and type in the IP address of one of the other two computers, I can access them that way. But why don't they show up on the Network list? What do I have configured wrong? Obviously, I CAN use the "apple-k" connect-to-servers-by-typing-in-the-IP-address method, but it's not as "nice" as having them just show up in the network window.
I'm sure it's something simple that I missed, and I'll probably feel like an idiot when someone points it out, but fire away folks!
G4 867Mhz Mac OS X (10.4.8)

make sure you have your automounter running. Do this in a terminal to make sure:
ps aux|grep -i automount
If it is not running, you may have turned it off using some utility (bad idea). It's controlled by the NFS startup item and should be enabled so the OSX API can listen for traffic on port 548, which is the Apple Fileshare Protocol port of register.
if this is confusing, I can give more detail when I arrive at my home.

My Macbook no longer sees other computers in my network

Hello,
I hope this question isn't too strange or difficult. This morning I booted up my Macbook to work on some grad school assignments in a different part of the house since my son was watching TV where my desktop computer is. All of my files are on my desktop, and up until today I have never had an issue connecting to my other computer to access them. Today was different. The "Network" icon does not show up when I open a new Finder window, and my other computer does not show up under "Places" in the Finder window. I have not done anything different, which is what baffles me. I have a wifi network at home which I am currently connected to.
Can anyone help me see other computers in my network again?

The "Network" icon does not show up when I open a new Finder window
Open up System Preferences/Internet & Wireless/Network - select Airport & put a check mark next to *"Show Airport status in menu bar."*
Right below the status box click on the "Assist Me" button and then the Diagnostic button. Follow the instructions.

I'm seeing other computers "in the network"
