Network shares disappear in Finder on OS X Lion

We purchased a new 21" iMac with OS X Lion installed. We have seen several problems with this machine since the beginning. One of them is network shares disappearing after a while in the Finder. I've had this issue a couple of times so far.
The shares are a Macbook, a Mac Pro, my Time Capsule, a Synology share (using AFP), and MacBook Air by BTTM. The only way to solve this is a reboot. Disabling and then enabling File Sharing in the Sharing Preferences doesn't work. Relaunching Finder doesn't work either.
When I tried to reboot the last time, the computer closed everything but didn't shut down, it hung at the wallpaper. I logged in using SSH to reboot it gracefully.
Does anyone know how I can diagnose and resolve this problem?
Thank you!

I suffer from this bizarre problem too.
In finder, when I copy and paste files from one folder/subfolder, to another folder/subfolder, It may not paste them at all; or, it may paste some of the files I copied; or, it may, correctly, paste every one of the files. The files that ultimately do not get correctly pasted briefly appear "shadow-like," then almost instantaniously vanish. This problem is erratic and substantial.
The files i ordinarily copy and paste are Office, iWork, or .pdf documents.
Please help, or engineer a remedy. Thanks, in advance.

Windows network shares disappearing when users are logged on to Mac

We are having some problems with windows network shares disappearing when users are logged on to Mac computers.
We have a number of Mac labs that users can logon to using their AD login credentials. Their network shares are saved on a windows file server. The ad plug has been configured on each client Mac as has the LDAP plug-in. It is configured to connect to the Xserve which is running as an OD master. The system preferences for the client Macs are being managed from the Xserve.
The problem for the users is that they can log into the Mac no problem and they can see their network share appearing on the desktop and in the dock, but for some reason on random Macs and with random users the network share disappears. If they log off and log back in again the network share is still missing. As it happens randomly I can not put my finger on what the problem is.
Most labs either have Intel iMacs running 10.4.11 or Intel iMacs running 10.5.5
Any help will be appreciated

Mike,
We need to know some basic scoping information to provide any further input.
1)
Is the user prompted that the server will be shutting down?
2)
Does Task Scheduler show that the task ran at the scheduled time?
3)
Are there any errors in %windir%\tasks\schedlgu.txt?
4)
Does the problem still occur if the machine is in its own OU with blocked inheritance?
Does the problem still occur in a clean boot configuration with MSConfig
Steps to clean boot machine:
================
Start > Run > Msconfig > Select Services > click "check box", "Hide all microsoft services" > Disable all
Start > Run > Msconfig > Select startup> Disable all
Reboot
Thanks,

Unable to reconnect to network share after closing finder window

hi there
I have not been a mac user for long - i have a macbook pro - and generally i am getting along fine.
however, I have a NAS box which I has a number of files on it on my home network.
I am able to connect to it using finder by doing cmd+k and selecting it from the list (which I set up at some point). and 'selecting the volume i want to mount' I am then able to browse the share happily and all is well.
However, once I have done what I was doing and then closed my finder window. if i open another finder window, the share does not appear anywhere and I have to reconnect, sadly at this point, after doing the initial cmd+ K and selecting the network share, the particular volume i mounted before is greyed out and I cannot in fact re-mount it at all.
I imagine this is because somewhere, finder still has the network volume mounted, and if I could only find it I could browse it as before.
so i am left with having to reboot, as I simply dont know how to find the mounted volume.
it may be that it is in fact not still mounted, in which case I am stumped.
if anyone could offer some explanation and solution to this, i would be most grateful.
many thanks
nat
ps. having fired up the terminal, it seems that the volume in question is in fact in the /Volumes folder, but I cant seem to find that in the finder.
pps. saying the above - actually as I installed XtraFinder I can navigate up until I have the root level and it is indeed there

I had the same problem. While logged in as root, I can't use an alias or Cmd+K to connect to a server, but it works fine as any other user. I tried the link above and after reading the mount_afp man page, it describes two steps needed to mount a server. Here's what I had to put in Terminal to mount a share called Installers:
The root account does not seem to be getting past the first step when using Cmd+K or an alias to a network share, although this worked in previous versions of OSX.
This problem was not fixed in 10.7.1

Windows 8 offline files on network share disappear after offline reboot

Hello,
We are using Group Policy Preferences to map a drive for our users. Windows 8 users who make this drive, or some of the files\folders in it, 'Always available offline' are finding that the network drive disappears completely if they do an offline reboot.
Windows 7 users are fine - their drive\files\folders continue to be visible and available even after an offline reboot.
Our domain is Windows 2008 R2.
I've had a look around for suggested solutions to this issue. So far I've tried re-initialising the offline
file cache and ensuring that hotfix 2795944 is installed on the Windows 8 machines as these seemed to fix similar issues for other people. However, neither have worked for me.
Can anyone suggest anything else that might solve this issue please?
Thanks in advance for any help.
Ros

Hi Roger,
Thanks for your reply, but I'm afraid your suggestion hasn't worked.
I added that DWord value ([HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System]
"EnableLinkedConnections"=dword:00000001) into the registry and rebooted while connected to our network. When
I logged back on, I'd lost my network mapping completely. I ran a gpupdate /force to reapply the group policy. When I logged back on, the drive mapping was back but incorrectly - it was mapped to the root of the 'Users' directory on the file server
instead of users\username as it should be.
I deleted the registry key, rebooted and my drive mapping was back to users\username as expected. However, it still loses the mapping as soon as I do an offline reboot.
The 'Reconnect' option is not checked in our Group Policy.

Network shares disappear from desktop

Hi,
I have searched but cannot find a thread which outlines the problem I am having.
I have a 40 strong iMac network with 2 Mac Mini servers. All iMacs are running Mountain Lion (10.8.2) with the Mac Mini's running Mountain Lion (10.8.2) and Server (2.1.1). I have a number of network shares defined which are hosted on a Pegasus array connected via a thunderbolt cable to one of the Mac Mini's. The shares mount as part of the login profile for each user.
The problem I am having is that the desktop icons for the shares randomly disapear from the desktop. This typically happens to 2, 3, or 4 of the shares but never all of them at once. When I go into the Connect to Server option in Finder and connect to the server hosting the shares they appear as available for connection (i.e. they are not greyed out as if an existing connection exists with the share).
As a general rule, the end users leave their machines on overnight and don't usually shut them down.
Can anyone shed any light as to why these shares seem to be randomly disconnecting / ejecting?
Cheers,
Tzukius.

Kevin,
All shares are done via AFP. When I look at the stats on the CPU on the server app it is hovering around 3-5% for a 4hr average.
One thing I have noticed is that on my machine I never lose the connections, co-incedentaly, my machine never enters sleep mode whereas the other machines are set to sleep after 30mins. I'm starting to think that this may be the cause of my problem, even though the ethernet interface is used for connecting the machines to the network and not the wireless connection (I had read on a couple of other threads that this can cause the disconnection of network shares).

Network Shares Disappear on Wake From Sleep

I recently got a Mac mini to replace an aging Mac Pro. I copied all my data over and everything is running great, and much faster overall. But I'm having one strange bug. When I put my Mac mini to sleep, it wakes up and all of my network shares are gone. I have 4 shares I keep connected all the time, and many more I use occasionally. All of these servers are Macs. I never had an issue like this on the Mac Pro, in all it's years of service. Including the time it was running 10.8. But now, the mini dumps shares - I think every time it goes to sleep, if not, almost every time. It's a real hassle having to reconnect to each share every time you wake up. Plus it's no fun having open documents dissapear either. My network settings are pretty simple, my primary connection is gigabit ethernet. It's first in the "service order" list. I also have airport enabled but not connected. I leave it on so my computer can have location serivces. This is all exactly the same as the setup in the old Mac Pro.
Any ideas?

If you must put your computer to sleep, you could use an applescript to re-mount your network shares when you wake it up.
tell application "Finder"
mount volume "afp://servername.local/sharename" as user name aUsername with password aPassword
end tell

Network Drives Disappear from Finder Intermittently

I'm periodically having problems with my Mac recognizing an Iomega Home Media Network Drive. Everything's connected together using an Airport Extreme. Usually the drive will show up under the "Shared" category in the Finder, and I can connect and use it normally.
Every once and awhile, it disappears from that list. I can still connect manually using Go->Connect to Server, but the Finder doesn't pick it up on its own. After a few days or weeks, it'll just show up in the shared list again. No amount of restarting/repairing permissions will fix it. For example, my drive has been missing for about a week now, and after doing nothing special it decided to show back up while I was typing this post.
I've seen this topic come up periodically on the boards, but I couldn't find anything recent or with a solution. Has anyone encountered or come up with a fix for this?
Thanks,
-Jason

I have an Iomega drive that is also fidgety on the network, either in Leopard (when problem arose) or SL (when I found my solution). I actually had to view my drive under the sidebar path ComputerName> Network> AirPortEx> Iomega Drive because I kept getting errors when I tried to view in column view from the shared section despite having the drive set to ignore permissions.
Firstly, this is what I call a workaround, not a fix, as recognition of the drive doesn't work seamlessly in Finder as advertised, but required these extra steps in order for me to always see the drive in the sidebar. Secondly, it may not be absolutely necessary to do all these things, and I am assuming you have the authority on your network to do all these things, but here's what I've done to get my satisfaction:
1. Make sure you set servers to mount on the desktop in Finder prefs and that connected servers and bonjour computers are set up to show in the sidebar
2. Use connect to server if you have to and mount the drive to your desktop
3. Once the drive is on your desktop, open system prefs and go to your login items under Accounts & Authenticate by clicking the lock on the lower left and entering your password
4. Drag the network drive into your login items (and dock, sidebar, or window toolbar if desired)
5. Restart
This may not be the fix you hoped for. You do seem to have to keep the drive mounted, etc. But I do always see it in my sidebar under sharing now, and have no problems viewing anything on it from wherever in the Finder I try to access it (whether from the sidebar in the shared section or under the network area of my computer, in the dock, or from the toolbar). At the very least you never have to Connect to Server again. Hit the drive icon in the dock and it will connect if you get disconnected.
FYI: Make sure you always choose the "ignore" button when/if alerts pop up to tell you that you have been disconnected from the drive because you'll have to remount otherwise. These alerts occur to me only when waking my MBP from sleep. I wait 2-3 seconds, and click on the icon of my Iomega drive that I have in my sidebar, toolbar, or dock and it shows contents just fine, still connected after all.

After waking from sleep, I lose all my network shares

On my MBA with 10.7.1, after I wake it from sleep and after my wireless kicks back in, I lose all my network shares and the only way to get the back is to turn wireless off then back on. Once I do this I can select my other computer on the network and everything pops back up instantly.
I've tried this same scenario many times and each time the exact same thing happens. I wake it. Network comes back up and I can access the Net. I see my network shares disappear. I select the computer I'm trying to get to and it fails. I turn wireless off/on. I select the computer again and it connects instantly.
I've never seen this behavior before and certainly not with 10.6.x running everywhere. Now I have 10.7.1 on my MBA, wifes MBA, and my iMac (which is computer I try to connect to). This same behavior happens on my wifes MBA as well.
Any ideas? I'm going to update to 10.7.2 and see if that does anything. Hopefully it doesn't break something else!
Anthony

And 10.7.2 didn't fix whatever the problem is. Weird...

Network shares keep disappearing

So I have a MacBook Pro connected to my home network via an AirPort Extreme. The AirPort connected to a LAN cable that then goes to my network's switch, router, and modem.. so the AirPort is set to act as a bridge. A couple days ago I mapped a network share (a drive on my server which is a PC) on my Mac. So the drive "Nick" was sitting on my desktop. Then I opened up Quicksilver and told it to catalog "Nick". This all worked.. but then I go on my computer the following day (without turning it off in between) and my network shares have disappeared from my desktop and Quicksilver no longer finds things on "Nick".. Even if I remap the network share Quicksilver can't find anything on it. I've had this problem before with a Mac Mini I used to own.. Why does OS X seem to forget about my network shares after a short period of time? Any help would be great.. Thanks!

It should've fixed it really, but in the past, I've had trouble with Macs "partially Sleeping" after Energy Saver was once used to Sleep it... seemed like some component of the OS still thought it should go through the motions, even though it never was sleeping... at least it appeared that way to me!?
We did restart everthing right?

How Do I find out what app is auto-mounting a network share and stop it?

I have a new laptop, the 13" rMBP. I installed Steam and wanted to use the network share on my server to store the game files. Everything went OK. I closed Steam, disconnected the share and shutdown my laptop. When I opened my laptop later on at work, it started to try and mount the network share.It keeps on going it. I removed the Steam app and all files related to Steam that I could find. I've looked at fstab, auto_home, auto_master and a large list of other files and directories and I *still* cannot find the offending file that's auto-mounting the share. It's really frustrating.
The share auto-mounts when I am home but not on the desktop or in finder. I find it by looking at /Volumes/ in terminal. If I mount the share manually under /Volumes/ it shows as Games-1 and mounts on the desktop under Games.
Does anyone have any ideas on where I should be looking to find the offending process/file/daemon?
Thank you!
Trevor

thanks for the reply but are you sure about this? What difference would it make? Why 5 apps?
Even if it does work, which I doubt, at some point, I will have to resync ALL my apps again and surely the same thing will happen again, and I will be none the wiser. I still won't know which app it is. There must be a way of finding this out.
Any ideas?
What is really freaking me out is how it is connecting to my carrier (who is charging me) with Cellular data switched off.......?
Thanks again.

Network Shares stopped showing up in Finder

Hello,
My MBP has been working perfectly for over a year. Two or three days ogo it looks like the computer stopped seeing all network shares. Almost like nothing that should be seen with Bonjour is showing up. Printers, Time machine backup server (QNAP NAS), itunes libraries on other machines, etc. I can get to things by using their IP address so the network seems to be fine.
The firewall is completely turned off on the Mac and all the computers are connected over a single switch.
I tried deleting systempreferences and reinstalling the last combo update but neither solution worked. Running the latest version of Snow Leopard with all the latest updates.
The windows machines are having no trouble seeing each others iTunes libraries. When I start up iTunes on the windows boxes they briefly see the Mac iTunes library although it disappears from iTunes home sharing if i try to access it.
Would appreciate any help.
Thanks,
Chris

Completed a Time Machine backup to the last restore point which was before the issue and everything is looking good so far. I will install the latest updates and see if I can narrow down this issue if it happens again.
TimeMachine is awesome. Super easy to restore my machine although it did take 3 hrs.

How can I automount a network share in Finder?

Currently I have to browse my network computer under "SHARED" and manually drag/drop the shared folder into Finder under "DEVICES".
Is there a way to do this automatically?
See the images below:

http://img.photobucket.com/albums/v154/3eleven/Mac/network-share-osx-02.jpg

Nope again.
Finder doesn’t have any option to display Network Share, only Connected Servers.
See image below

Ive been searching for a solution for this since Tiger. At least they fixed a number of Network share issues with Leopard, but they still dont have this fixed.

How can I increase the speed in which Finder refreshes network shares on AD network shares

We have 20 Mac's running OS X 10.7.4 all fully patched. We are running a RAID Array off of an HP Proliant 370 G6 with 48 GB RAM. This server is also acting as our Domain Controller running Windows Server 2008 R2.
We disabled the Mulitcast broadcast and changed IPMonitor.bundle file to timeout after 1 second instead of 5. This allowed users to mount their network folders in 3-7 seconds. Used to take upwards of 2 minutes. We also added our domain to the search domain field in the advanced network
Now the problem is that when the designers go to one of the network shares that our preflight software (running on a different server) deposits the files to it can take between instant refresh and 30 minutes. Some clients will update faster than others. No consistency to issue.
We installed the finder refresher app but this did not work either.
I know their are mixed feelings on Mac's bound to AD networks. I have scoured the forum and other sites. Please advise as to any other modifications to either the server or the client machines that will help.
Bandwidth is not an issue. Gigabit to a Netgear switch and a fiber line from the switch to our main switch. At peak use server bandwidth may hit 30-40 percent of capacity.

Apple menu > System Preferences > Network > Advanced > Wi-Fi > Drag networks into the order you prefer.

Finder crashes when trying to connect to network share

Hi!
I've just upgraded my Mid 2012 MacBook Pro to Mavericks, and found that Finder always crashes when trying to connect to my office network share via an IPSec VPN connection. It's a Synology DiskStation NAS, so i have the options to connect via AFP or SMB, however both result in the same, the crashing of finder. Even after i relaunch it, i can't open finder, and can't even shut down or restart my system (only by holding the power button for 5 secs...)
At first i thought it's the result of the latest Little Snitch version, but the problem remained after completely removing Little Snitch.
Unfortunalely i won't be able to try connecting to the NAS on the local network until monday, but i'd really appreciate if someone could point me to the direction of some solution as this way i can't do any of my work.

Just a quick heads up. I finally managed to resolve the issue. It seems that mavericks doesn't handle the MTU of the vpn connection correctly, so i ended up modifying the MTU on the VPN gateway.

Find network share process and kill it

Hi All,
Is it possible that we could find open network share access process and kill it?
For example, user is opened a folder via network share (e.g: \\myserver\c$\myfolder). Is it possible that we could somehow query process to identify this open network share process and kill it before attemp to delete C:\myfolder? Please advise.
Best Regards,
Andy Pham

You could try checking for open file handles, as described here:
http://stackoverflow.com/questions/317071/how-do-i-find-out-which-process-is-locking-a-file-using-net. They have both a solution using an external executable utility (SysInternals) and one using PInvoke. You could also use this other utility which is specifically
targeted at hosts of network shares:
