Network drives disapperared

since upgrading to Yosemite 10.10 I have to re-map my network drives every morning
can someone explain to me why this is happening.

I tried the "usual" reset of PRAM and SMC and now it seemes to work correctly!

Error message when mapping to a network drive of a DFS share on Windows 7

Hi,
We are getting the following error when mapping to a network drive of a DFS share on Windows 7:
“The mapped network drive could not be created because the following error has occurred:
A specified logon session does not exist. It may already have been terminated."
In our case, the user logs on his workstation using his regular domain account, then maps to the network DFS share using the service account of an application.
There is a fix from Microsoft (MS KB968264). But this fix requires disabling the "Network access: Do not allow storage of credentials or .NET Passports for network authentication” property. This is against the Microsoft own best practices (Network access:
“Do not allow storage of passwords and credentials for network authentication” should be set to
ENABLED), and is NOT acceptable for us for obvious security reasons.
Question: Does anyone know an alternative fix to this issue that does not introduce security risks?
Thank you in advance!

Again I have tried this, but in my program if I try to save to the a drive when no disk is inserted, the JOptionPane i want to display is not coming up.
the system prints out
java.io.FileNotFoundException: A:\image.jpg <The device is not ready>
If that makes any sense to you

Hello i am using TimeMachine to back-up entire Mac image (data + system) on an usb-local drive. I would like (on top of it) add a specific plan to back up some files on a remote network drive. Does TimeMachine support multiple back-up plans ? How ?

Time Machine is capable of backing up to multiple locations, and can be used to back up to both a local hard drive and a networked drive (provided that that drive is in or connected to a Time Capsule or another Mac that is sharing it over the network). The catch, though, is that you can't specify different things to back up to different destinations. Whatever you exclude from Time Machine backups is excluded from ALL backups, and whatever is included is included on all.
So, get a large enough drive that you can back up everything you want in all locations, or use something else for maintaining the network backup.

Hi,
Is there any error message throwed when you reconnect the mapped drive? Can you directly access the UNC path of the mapped drive? What VPN programs do you use? Please check if the VPN client connect correctly.
You could refer to the thread below to check if the AD account is restricted by VPN.
Can't access mapped drives through VPN when away from office

Hi,
How did you map the network drive? Manually via GUI? Command? GPP? If you're using one of the above solutions, then try other solutions as a alternative way to check the result.
According to your description, If Windows remains unable to reconnect mapped Network Drive at login, then I would suggest you created a batch file with net use command, use it as an logon script, this provides an alternate way to reconnect drives on
a re-logon.
example
@echo off
net use * /delete /yes
net use x: \\server_name\shared_directory_name

Can you view network drives in Bridge?

I am currently using a trial of CS4 and when I go to bridge to select the files that I want to import into Lightrooom ( the one thing I don't understand about lightroom not having a browser to see the pictures before you import, I think this is crucial to good workflow ) I am unable to see any of my network, however my 1.4 version of Lightroom can see all the network. I am probably doing something wrong can anybody help?

I hate to say this but you sound a bit distressed and aren't understanding me. I specifically stated that in my scenario I am able to view network items such as computers on the network that are unmapped but are connected to the network. I can go into those computers by twirling the triangle and viewing the shared folders. within those folders I can view items that are part of that drive. I can ALSO see mapped network drives and their contents. I did experience a single problem of not being able to view two large folders on a network computer but it did not say "building criteria". Usually "building criteria" only appears if you are "searching" for something. You might try waiting for the criteria to finish building which could take some time in Bridge, since when it takes this step it is searching according to index and non-index criteria. If it is non-index then it will be slow to respond to your search. If Bridge doesn't work properly you might try to contact Adobe customer support if you purchased the product recently and it is under warranty and registered to you. You cannot, as you said, open a file in CS4. CS4 includes Bridge and a host of other applications based on what version of CS4 you have. Please try to be more specific when you post as to the steps you took to reach your point of difficulty with the software. Network in Bridge is located under the "Desktop" icon in Windows. You have to twirl the Desktop in order to see the Network.

Unable To See Network Drive from outside Home Network..even when using DynDNS

Hi
I have just got a Freecom Media storage Network Center which I have attached to my WRT150N router.
I am attemting to permit access to authorised users to files on the drive via the internet (presumably via ftp).
Here is what I have done:
Swiitched on DynDNS on the web admin page in the router (used DynDNS.com free service.
Obtained a user addess which is middle-earth.dyndns-home.com from DynDNS, which is linked to my Virgin Media IP
Switched on Port Range forwarding with
Ports 20-21 as ftp
Port 80 as http
Port 57 as DNS
Selected "both protocols"
Set the IP address to route to 192.168.1.42 - (this is the IP address which the web based software for the Network Drive reports as.
However the configuration of the TCP/IP protocol in PC attached by LAN cable to the router is "Obtain an IP address automatically" (i.e. dynamic?). If I change these settings and specify static IP addresses   will I not muck up internet connection to Virgin Media.
what I was hoping to acheive was typing     ftp:// middle-earth.dyndns-home.com
in the address bar would let me see the network drive from anywhere!
I have tried using DNS pinging on Ports 20, and 21 but that tells my ports are closed. i have also tried switching off my software firewall (Kaspersky) and the router firewall, but this does nothing.
What have I done wrong or no done!!
Thanks

I think the problem is solved.
The Freecom device needs to use a different part of its interface to be assigned a static IP address, which I have now done. At my last try it was visible from two independent views outside of my network.
On another front, I am appalled at Linksys or Cisco, who are not prepared to advice on getting more from their produicts if they are 'out of warranty'. The online chat tech said I could ring an 0871 premium line number in the UK. When I rang that, I was told as tthat as my unit is not faulty and was out of warranty I would have to use their pay per incident service.
That is not a way to deal with customers. When it comes to upgrading or replacing network equipment, I will look to a provider who is interested in their customers.

Copy a file from local drive to network drive!

The subject says it all but I'll explain. I have a web application that runs on a tomcat and mysql. I have a bunch of clients in a local network that uses the application.
Server is running Windows 2003 server and clients are running windows XP.
On a client request a file is created on the server in "temp" folder. The file name is "justAFile.txt".
On the client pc a folder "temp" is shared for reading/writing.
What I want is the server to take the IP address of the client, and then based on that address to copy the file "justAFile.txt" to it (for example "\\192.168.0.20\temp\" - that is the client address).
I have the address of the client:
String userAddress = request.getRemoteAddr();I use this code:
FileOutputStream outFile;
PrintStream p;
String bonFileName = (justAFile.txt");
String destinationFileWithPath = ("\\\\192.168.0.20\temp\\skladPrint\\"+bonFileName);
try {
    outFile = new FileOutputStream(destinationFileWithPath);
    p = new PrintStream( outFile );
    p.println ("a textto be written on a file");
    p.close();
} catch (Exception e) {
     %>Error writing to file<br><%
}This code can create a file on a local drive with no problems, but when I try on a network drive it fails. Even for testing purposes I set the shared folder to a maped drive "Z:", and again no luck.
I've spend all my day till now in reading articles in inet, but haven't found one that will solve the problem.
I also tried creating a batch file (exec.bat) that has in it:
move \temp\*.txt \\192.168.0.20\temp
and then executing it with:
String[] executeCommand1 = { "cmd.exe", "/c", "\\temp\\exec.bat" };
Process p1 = Runtime.getRuntime().exec(executeCommand1);
p1.waitFor();But again no luck. When I execute the file from command prompt, it moves the file to the shared folder, but when I start it from the java application with the posted code, it DOES NOT move the file...
Any help will be appreciated...

Try using the jCIFS project. This package allows you to access shared folders on a PC if you have a good username/password.

Creating a folder alias on a shared network drive

Hi,
I have a folder that is housed on my computer that I would like an alias of on my company's shared network drive. I will have access to the shared network drive from my home computer either through Citrix or a VPN, so I would like the alias on that drive so that it will reflect any changes I make to the files within either from my work or from my home computer. My question therefore is, how do I create an alias of a folder on a shared network drive? I tried creating an alias on my local drive and then dragging it to the shared network drive, but that just copied the folder and removed the alias.
Any help would be greatly appreciated!

Nevermind. I must have copied over the original folder the first time instead of the alias, as a simple drag and drop of an alias folder just worked fine for me.

Error saving Project 2010 files to network drive - doesn't see network drive

ANSWERED (11 April 2014):
So it seems the resolution to this is to simply create a new share with a different name. I used the existing folder (to retain NTFS permissions) and just select to Add a new Share (applying the same Share permissions as the non working Shares).
Deploying this new Share via Group Policy as a test resulted in staff being able to open files from Windows Search, save files through MS Project and the Share being accessible through browsing SMB.
All problems resolved by using a new share name for the existing folder. Seems to be a corruption in the namespace.
Note: I had previously deleted the share and recreated it. I had removed all NTFS permissions and readded (through both the GUI and icacls). This didn't make a difference.
Only changing the name of the share fixed the problem.
Original Question
Already
posted here... but Microsoft Support has not responded.
It seems some staff on some computers are having problems saving MS Project files to the network. This is only since an upgrade to SBS2011 (from SBS2003). The only difference now, is that network drives are mapped via group policy rather than a 'net
use' script.
This is affecting users on Windows 7 and Windows Server 2008 R2, with either MS Project 2007 or 2010. The users have full change access to the folders and can create new files and modifying existing files, just not a MS Project file. Other file tyes, e.g
Word .docx, Excel .xlsx, Adobe .pdf files, all work fine. These files can be opened, edited and saved normally without problem.
To replicate this:
The user opens an existing file or creates a new file on the network folder (either through Windows Explorer or MS Project). They then click File > Save in MS Project and receive the following error (see pic below):
An interesting symptom of this is that if you select File > Save As in MS Project, the Sae As dialog box doesn't remeber the path location of the network drive. MS Project instead prompts to save the file in the local users documents folder (see pic below):
If they browse back to the original folder where the file was saved and choose to save it there, they are of course, prompted to overwrite the existing file and they can save the file. But the same thing happens every time they open the file.
It seems the problem is that Project isn't seeing the path of the file or that the network drive is attached.
If a user closes the file without saving it, they are prompted to save the file and the prompt shows the drive path:
Do you want to save changes to "N:\... Projects\Active Projects\CC...\F4 Project Plan File\004 Programme\test project file.mpp"?
But choosing to save the file gives them the same result as Save As, they are prompted for a new location as if the original file location doesn't exist.
I have disconnected the mapped drive and connected it again using net use but get the same error.
I have reinstalled MS Project 201, installed Project 2010 SP2 and installed Windows updates and it does the same thing, exactly the same symptoms.
Further, if the user opens a file from the network drive, the file shows in the Project recent files list. If they try to open the file from the recent files list in project they get the following error:
"Project cannot open the file.
-Check that the file name and path are correct.
-Check that the file format is recognized by Project.
Project files saved in a version earlier than Microsoft Project 98 can't be opened...."
This is a test file that I created on the user's computer and network drive, This is being opened with the same version it was created in. If I browse to the folder in Windows Explorer I can open the file. Of course, I then can't save the file (I still get
the original error). I'm logged on with Domain Admin privileges.
I've checked these links from other threads (neither apply to my scenario):
http://support.microsoft.com/kb/983458/en-us|
http://social.technet.microsoft.com/Forums/en-US/excel/thread/2eeea140-7e6c-4cb9-a89b-06d2102bd9f7/
I've downloaded my TechNet version of he software and installed it with Sp2 and Windows updates and it does the same thing. This also happens on the Remote Desktop server (Server 2008 R2) using MS Project 2007.

Case 1
This error message appears when the document is open on two or more computers that are running different operating platforms. For example,
if the document is open on a Macintosh computer and you open it on a second computer running Windows or Windows NT, the error occurs when either user tries to save the document.
This problem stems from a difference between the ways Macintosh OLE and Windows OLE open files. As a result, you cannot save a file on two different operating platforms at the same time.
Case 2
This error occurs in Word 97 for Windows if you save to a MAPROOT type network drive connection on a NetWare server where spaces exist in
the file or folder name.
Case 3
This problem may occur if an anti-virus program running on a network has the ability to scan for macro viruses in documents in shared network
folders.
For example, if you have the following:
a shared folder on a network server
-and-
an anti-virus program is running on the network server that is set to monitor the shared folder,
when you attempt to save a document (across the network) to the shared folder, the anti-virus checker may cause the error to occur.
Case 4
This problem may occur on Novell networks when the AutoRecover files path is either blank or set to a network drive.
According each, please try the following workaround:
WORKAROUND
To work around this problem, use one of the following methods appropriate to your situation.
Case 1
Method 1:
Move the document to your local hard disk for editing. Move it back to the server after you finish.
Method 2:
Save a copy of the
file with a different
file name, and work on the copy, either on your hard disk or on the server.
Case 3
Method 1:
Move the document to your local hard disk for editing. Move it back to the server after you finish.
Method 2:
Do not use spaces in the directory or document names.
Method 3:
Do not use MAPROOT-drive connections. Map your drive connections to the volume-level only.
Case 4
Turn off the anti-virus protection on the network server and then try to
save the document. Contact your anti-virus protection software company for additional details and/or updates to their programs.
Case 5
Set the AutoRecover files path to your local drive. To change the AutoRecover path, use the following steps:
1.
On the Tools menu, click Options.
2.
On the File Locations tab, select AutoRecover files and then click Modify.
3.
Change the Modify Location dialog box to a
folder on your local drive and then click OK.
4.
Click OK to close the Options dialog box.
Hope that helps.

Finder windows close randomly on network drive

Hi, searched on google for long time and found nothing. I'm working in a small office (13 iMacs and Mac Pros) and the Finder have a strange behavior.
In my office, 12 iMacs and Mac Pro are using OS 10.6.8 to 10.8.3, and there is a server that contain a backup of every project and every user must save his project at the end of the day on the server. The server is a Mac Pro first generation with 8GB RAM running 10.7.5 server, and a 2TB HD that is shared with everyone.
When a user want to access a folder on the server drive, the windows of the folder randomly close.
For example : User A want to save his project in folder "Macintosh HD:Client X:Project Y" So User A open the remote "Macintosh HD", than "Client X" folder and "Project Y" folder, but "Project Y" close by itself. User A must reopen it from "Client X" folder. I have a lot of complain since it's irritating and a waste of time when you want to drag your document and the target folder close by itself. It's not a lost connection since the remote drive stay mounted. The problem was there when the server was running 10.6.8 and I tough that the upgrade to 10.7.5 server will solve that, but no luck. Since it's a 1st gen Mac Pro, we can't try 10.8
The problem affect client on every version os Mac OS, from 10.6.8 to 10.8.3
Any idea ?

What is your network drive attached to? Is it a NAS or a shared drive from another computer. Either way get it connected locally to a computer and you should be able to find a file undelete tool (there are even free ones) that can restore the files that you have deleted.
I've written a script called DeDuper which can help remove unwanted duplicates. See this thread for background. The thread may shed some light on exactly what you did wrong. ITunes shows all the copies of the files that are the same as each other. If you delete them all you end up with none.

Network drives do not show up on Desktop or in Sidebar

I have a user who is experiencing a weird problem. When they connect to a Windows server over our LAN, the server does not show on their desktop, nor does it show in the sidebar.
I have checked the boxes in Finder/Preferences to show network drives on the desktop and in the sidebar, but the network drives do not show up.
I have reproduced this on another Mac, a G4 also running 10.5.8 .
The windows servers do appear in Go/Network, and the user can connect to them, but they still don't show up on the desktop or the sidebar.
Does anyone have any good ideas about this?
Thanks in advance!

Templeton, I'm sorry if my message wasn't clear, but I have already tried that.
I'm beginning to wonder if there might be some issue with this in 10.5.8, since this works on the Macs here with Snow Leopard, and it used to work when we had Macs on earlier versions of OS X.
Again, I'm open for any ideas on this.

I am trying to delete an XLS file from a network drive and am getting a message that says the file cannot be deleted because it is in use. I can't see where it is in use and have tried to reboot the computer to no avail.

I am trying to delete an XLS file from a network drive and am getting a message that says the file cannot be deleted because it is in use. I can't see where it is in use and have tried to reboot the computer to no avail. I can delete other files but several XLS files are giving me this message.

You said it was a network drive. So is someone else on the network using that same file or may have have left with excel still accessing it on their system?

Can't copy file to network drive as "The operation can't be completed because the [Filename] is in use

Following upgrade to Yosemite I now can't copy files from iMac to my network HDD in external media center. I have iMac connected by wi-fi to airport extreme and media center connected to airport extreme by cable. I can see the HDD as a network drive on my iMac and can initiate the copy but right when copy process is finished I see "The operation can’t be completed because the [Filename] is in use". I am trying to copy different media files downloaded from internet which are not used by any program and stored on my hard drive. I actually can copy small files of 1mb and it works but anything above 20mb is halted. I can also move/copy/delete the file on iMac. Cant understand the nature of the problem. I tried to format external HDD as EXT2/EXT3/NTFS but same outcome.

Password for network drive (default?)

When I added a network drive (Ethernet) to my system, my Mac asks for a 'registered user' password. Since I haven't set up a password how do I get access? I have the option of logging in as a guest but does this limit what I can do?

If this is a third party (non Apple) drive, you may want to check the manual or online for a default username/password on the manufacturer website. Typically, it may administrator and no password.
If this is a used drive, the previous owner may have it.
What make/brand is the drive?
If it has a USB/TB/FW connection rather than Ethernet, try that as well and see if DU will see and allow a re-format?
