Cannot connect to other computers on network. HELP!

Using a G-5 dual 2.0 with 10.4.10 and I am having issues with networking and connecting to other computers on my network. This is an intermittent problem. When I try to connect <go> <connect to server><browse> the computers on the network do not show up(in the network window) all the time. Sometimes they will if I restart and sometimes not. Why is this happening? I have 4 other machines and they are all fine. I can connect to if but not from it.
TIA

Cannot connect to other computers on network

We have a small office network with 7 macs on it. 5 wired 2 laptops with Airport Extreme.
We have an 8 port switch where the 5 desktops and the airport connect. When I am on a laptop I cannot connect to any of the desktops. It does not even see them (and same with desktop to laptop) What do I need to do to share these two on the airport

Configure the AirPort Extreme base station (AEBS) so that it the option to distribute IP addresses is DISABLED. That will place the wireless and wired computers on the same subnet.

Cannot connect to other computers over wireless on my AEBS N base-station

Cannot connect to other computers on network. Can connect to Airport disk, but not my desktop (iMac G5) or vice-versa (Macbook). Can see it on finder sidebar, but clicking on it just "connects" for hours, with no success. Finder-->connect to server does not work with IP or name.local. Tried rebooting, deleting kerberos, deleting .mac certificates, unplugging, prayer and animal sacrifice. No luck. Anyone have any suggestions? Firewalls are both turned off, BTMM turned off, airport on, both connected etc. Console logs are spitting out LOTS, I can post if necessary.

Unable to Connect to Other Computers on Network

We have a small network of 4 Macs and suddenly one of our computers cannot connect to other computers on the network. We have file sharing turned on all the Macs, and the other computers can connect to this G4 733 DA, but the G4 DA can "see" the other computers, but when I try to connect I get the message that the connection failed.
Is there any solution other than reloading Tiger? In system 9 it was simple to just reload the networking extension if it was damaged, but I am not sure for what to search to fix this problem.
G4/1GHz, 7600 w/G3/500 MHz , G4/733 MHz Server Mac OS X (10.4.4)

Since all the computers are "seeing" each other, I would try to do a "Repair Permissions" from the Disk Utility on the G4 DA...and, if that doesn't help, try the "Repair Disk" option before reloading Tiger. Sometimes, when OS X can't access system files properly, you see "strange" errors like these.

Connect as... no longer works. Cannot connect to other computers on my home network.

I have a home network and it's been unchanged for years. Never had any issue with connecting to other computers, all of which are Macs running OS X. Now, if I click Connect As, nothing happens. Double-clicking the other computer in the Finder's sidebar or using Go To Server, etc. yields nothing. Even odder; the other machines no longer see me at all. No one has any Firewall on. File sharing is on for all machines. We're all on the same subnet and the same network, yet every other machine can connect to one another but not mine. Thoughts? Restarting has not helped. Thanks.

If you are getting the error message that the server won't allow any more users to connect, and to try again later, this seems to be a problem with AFP sharing in Lion.
The workaround for this so far is to go to System Preferences > Sharing > File Sharing and click on Options... On that window, turn OFF "Share files and folders using AFP" and turn ON "Share files and folders using SMB (Windows)" Click Done to go back to the sharing window and you should see a green dot followed by "Windows Sharing: On"
Give that a try.

Cannot Connect to other computers on my router

I have a u.s.robotics sureconnect 9106 (adsl modem and router - the same as
9105) and wanted to hang another pc with xp pro to my xp pro machine. So
i connect the two via ethernet cable to the router, but i am able
to ping the other machine and to use ftp but neither of the two can see
the other in windows xp pro
the same with a osx machine witch i connect for checking itunes or sharefolders
I also try my xbox with xbmc for sharing and streaming my itunes songs
but it doesn't work at all, even after i open the two ports asked by
itunes - i also deactivated outpost but that neither helped - the
strange thing is that in the outpost/system/lan-settings outpost can't
even see the other machine
I can also ping it and ftp, but nothing more
when i try to connect then outpost ask me if i want to allow it and
afterwards when i try to close itunes then it says that another user
is in my library but the xbmc says that it couldn't connect...
what have i forgotten?
I not read here that the port 5353 should be udp and i have only give the tcp port free but after changing to udp itunes not even told me on the exit that another user has access to my database
ah well i have on my router a virtual server with the same ip as my
computer (192.168.1 ist the modem 2 ist my computer and the virtual
server and 3 is the other computer) and there i set the port holes for
the nat service (itunes etc) BUT i think because of that i have
in the network connections not even a internet-gateway but only
the ethernet connection
I installed xp pro new, but then the gateway only appears for some
seconds and then disappear. But lately for a while it appears but after
some time it disappears - maybe its because i try this time not to give
my machine a fix ip and then its possible that the gateway appears when
I have another ip than the virtual server on my router, and that then
outpost also recognize the other computer?
any idea what i did wrong, or i have forgotten, i really haven't a clue
what to to and i never haven't heard that when you have a virtual
server (nat) then its not possible not to connect to others
computers...
thanks for your patience

Bought my iMac in February and worked fine up until about a month ago. I have assigned a manual IP address outside the range of other devices in my network (e.g. 192.168.0.10) and this seems to do the trick (most of the time). The problem I had was the self assigned IP address wasn't in the usual range for my router so while I was connected to Airport and the internet I couldn't view any webpages. Had to do the same thing to my Macbook which I purchased about a month ago.
The strange and very frustrating thing is sometimes it doesn't recognise my preferred network but then when it asks me to join a network, my network appears! When I try to connect and confirm password, connection times out. Whats that all about?
The bottom line is the assigned IP solution doesn't always work but it seems a combination of issues rather than one. None of the other devices on my network (ReadyNas Duo, Xbox 360, PS3, Wii etc) have issue connecting to the router using DHCP but for some reason Airport has trouble dealing with this and assigning a correct IP or can't find the network all together.
Only thing I can think is its some Airport update that has caused these intermittent issues and realy hope they fix it soon.
So no update but just wanted to share my experiences in what seems a very wide scale issue...

Cannot Connect to other computers on home network

First let me say I am a new MAC owner. I have only ever used Windows PCs. I just got my Macbook today and installed SL 10.6.2. I can connect successfully to the internet and the networked printer on my home network. I cannot however, see or connect to any other computers on the home network. We have 2 other machines, one is running Vista and the other is XP. They can see and connect successfully to my Mac. I have read through a number of threads, but have not seen anything that I understand or can find on my laptop. Can someone please let me know what I need to do to see and access the windows computers.

Try using Finder > Go > Connect to Server > smb://ipaddress. If you can connect this way, then good. I'll have more to say later. Just try to get this working for now.
Before trying to connect:
On the XP machine.
1. Right-click on a folder to share (e.g., My Documents), chose Sharing, and select both Sharing Options.
2. Restart (probably not necessary, but I’d do it).
See how this part goes. I can't remember where some things are in XP, but you may have to enable Network Discovery somewhere.
On the Vista machine.
1. Go > Computer > Users > User; right click on the User folder, and choose the settings that give Everyone—both Read/Write permissions.
2. Go Control Panel > Network and Sharing Options > Turn on network discovery, Turn on file and printer sharing, Turn off public folder sharing , and Turn off password protected sharing (unless sharing won’t occur without turning it on).
2. Restart (probably not necessary, but I’d do it).
See how this part goes too. I can't remember some of the detail in Vista.
On the Sno machine,
1. Go System Preferences > Sharing > Check File sharing > Go Options > Enable SMB sharing.
2. Go System Preferences > Network > Select Airport or Ethernet depending on what you are going to be using. I am assuming you will be using wireless below. Let me know if not true.
3. Having selected Airport, select ask to join new networks and show Airport status in menu bar.
4. Click advanced > click remember networks this computer has joined > Click Wins > Enter the ip address of your Win7 machine in the WINS server box > Enter the Win7's workgroup name in the workbook box unless it already is there (look in the drop down menu too). In all likelihood the name is workgroup, but check on the Win7 machine.
5. Restart

Cannot connect to other computers on my wireless network

Since I upgraded to Mac OS X v10.7 Lion I cannot connect to my iMac or MacBook as a Registered User. I keep getting "Connection Failed" when I try to connect.

If you are getting the error message that the server won't allow any more users to connect, and to try again later, this seems to be a problem with AFP sharing in Lion.
The workaround for this so far is to go to System Preferences > Sharing > File Sharing and click on Options... On that window, turn OFF "Share files and folders using AFP" and turn ON "Share files and folders using SMB (Windows)" Click Done to go back to the sharing window and you should see a green dot followed by "Windows Sharing: On"
Give that a try.

We are using a WRVS4400N. How de we connect each others laptop? Are there any setings we should use?
I also has a wired desktop connected. It's not possible to connect to that one either, even it shows under "my computer"

Trouble Connecting to Other computers in Network

Hi. I have quite a few computers in our local home network, via an apple airport extreme. There's three G4's running Tiger, and a few G5's running Leopard. I'm able to connect to any of the 3 Tiger based G4's by opening the network, and selecting "share screen" on which ever computer I want to run. It works fine. However, I cant seem to log into any of the Leopard G5's from the G4 computers. I dont know if it has to do with the fact that, they're Leopard, or that they're G5's. Whenever I got to Network up at the top under the "Go" pane, nothing comes up when you click it. I tried manually connecting with their IP addresses using the "connect to server" function under Go, doesnt work either. None of the Leopard computers appear under the network, only the older computers. Any suggestions on how I can connect the Tiger computers to the newer Leopards? I dont see a share screen function anywhere on Tiger.

Okay, so you can get from a Leopard to a Leopard and from a Leopard to a Tiger okay then, right? But what you can't do is get from a Tiger to a Tiger or from a Tiger to a Leopard, right? And that's what you are inquiring how to do, right?
Tiger to Tiger: Unless you have paid the small phenomenal fee for Apple Remote Desktop Client program for your Tiger computers, as near as I can tell, you're going to have to use VNC to do what you are trying to do. This post has several links to some other posts that tell how to do VNC encrypted through a secure shell tunnel from across the internet at large, Tiger to Tiger; a little more than what you are asking; but a subset of those directions apply here. On your home subnet, you don't need to worry about tunneling through secure shell and in the VNC client program; rather than connect to "localhost:5901" as described in all those posts, you'd just connect to {computerNameOrIPAddressOnYourHomeNetwork}. However, all the descriptive text in all those posts about how to configure the Tiger machine as a VNC server, which requires both Apple Remote Desktop and VNC to be enabled in the remote server computer's System Preferences, still applies in the local subnet case just as it does in the internet-at-large case.
Tiger to Leopard: Can't be definitive on this one, but I would suspect that there will be a similar process to enable VNC server on the Leopard, as was described in all those Tiger-to-Tiger posts. Again, this assumes that you don't want to, or haven't already, put out a bunch of money for Apple Remote Desktop Client for your Tigers. If you have the ARD client, I am guessing it is a no-brainer for both the Tiger-to-Leopard and Tiger-to-Tiger scenarios. Otherwise, I don't see how you will get this capability unless you can enable a VNC server service (along with the ARD server) in the remote server Leopard's (and the remote server Tiger's) system preferences, and run a VNC client like Chicken of the VNC or JollyFastVNC on the local client Tiger computer that you are sitting in front of.
PS: and we're not worrying about file sharing or remote login not working, are we? At least not yet?

Connecting to other computers on network doesn't work as expected.

This is kind of interesting.
I do this: From Menu Go > Network
Then I choose either my iMac or MacBook Pro and double click the user name for my home folders on the other computers.
A window opens up and the bottom right of the window the little twirling busy thing just goes and goes and goes.
I notice the server icon on the Desktop and double click it and everything is there an access is fast, just like I expected from the first window that popped up. But it's still there, blank, with a little twirly thing (very technical).
I get what I'm after, but it doesn't work the way it should.

Try keeping your shares from sleeping during the expected period of use--assuming they are. If this procedure works, then you'll need to decide between the "lesser of the two evils."

Cannot connect to other computers or drives

Hi everyone,
I am unable to connect to any network drives or computers.
They show up under my "Shared" category on my finder, and everyone is able to connect to me just fine.
My internet is working fine too.
Under System Preferences > Sharing, File sharing is one.
Under the Options, AFP and SMB are both on, FTP is not (not sure with AFP and SMB are, but I thought I'd try).
I am connected to a Verizon Westell router with an Ethernet cable, as is everyone else.
Any suggestions?

Yeah that should do it and that is a safe choice so long as you are behind a router with a firewall and you implicitly trust everyone on your immediate LAN.
Unless you have Windoze boxes connecting to your machine, you don't need SMB.
When you authenticate as an admin user in System Prefs > Sharing, and you have file sharing checked and highlighted, are the folders that you expect to be shared showing up in the list of shared folders? And when you highlight each one of them one at a time, are the permissions set the way you would expect for user (owner), group, and everyone (else)?

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.

MacBook Air - Cannot connect to Ethernet Computers on WiFi Network

I just bought a new MacBook Air (11 inch) less than a week ago. Love it, its great. I am however having an issue with connecting it to computers on the same network, but only if those computers are connected to the network via ethernet (while the Air is on wifi).
I have an older MacBook (2.2Ghz running 10.7.2 also) with no issues connecting to other computers over the wifi if they are on ethernet. My old MacBook and the Air can also communicate no problem over wifi, but if I connect my old MacBook to the ethernet connection I cannot ping it from the Air.
The reason why this is important is because I am trying to hook the Air up to a buffallo linkstation to setup TimeMachine like I have it set up on my old MacBook.
I am using a Buffallo WZR2-G300N Router as my gateway and access point (I also have a D-Link switch, but I have by-passed that to troubleshoot the issue). Firmware is up to date.
The Air also has no problem connecting to the internets.
Any ideas oh Apple Support Community?? Many thanks in advance.

Itunes keeps on saying... Cannot connect to itunes. No network connection".. all other things/websites work except for itunes.

I need Help ASAP. Itunes keepson saying "cannot connect to itunes. No network available". I dont have have any problems with regards to wifi.

Can you try these entries in command prompt (Run as Administrator for Win7/Vista) one at a time?
ipconfig /release
then
ipconfig /renew
restart computer
ipconfig /flushdns
totally shut down computer then restart.
netsh winsock reset all
