Access unc windows shares like \\server\share\

I can mount windows shares both manually and from fstab.
My question is. Is it possible to access windows shares without explicit mounting, simply with unc like \\server\share ?
I need it because i host a web application and it need to serve many files on many windows servers with many different shares. Mounting all of them, and the future ones manually is a maintenance nightmare.

You can do it using fusesmb, too:

Remote Access to Windows 2008 R2 Server configured with local IP

Hello,
I have a Windows 2008 R2 Server configured with local IP (e.g. 192.168.1.115).
Please how can I access it remotely outside its local domain through (remote desktop connection).
Thank you.
Tony.

Hi Tony,
Based on your description, you would like to connect to the Windows 2008 R2 server via remote desktop connection.
So you need to enable remote desktop on the Windows 2008 R2 server if it is not already.
1.Install and configure the Remote Desktop Session Host role service in the Windows 2008 R2 server.
2.Add related user to the Remote Desktop Users group in the Windows 2008 R2 server.
3.Configure remote desktop connection in the Client.
Also, due to you would like to access it remotely outside the domain, so you will need a VPN connection or a port forward to connect through.
For more details, please refer to the guide below,

Remote Access to Windows Small Business Server System via VPN

Same old story: I use macs at home but I want to be able to connect to our small company Windows network over the internet to pick up and put down files.
Said company network consists of a server running Microsoft Small Business Server and Exchange. The data sits on some network drives (Z: etc, you know the sort of thing).
I've sorted out email access - I just connect to the Exchange Webmail interface and do all that using a web browser at home.
Now for data: well, I have successfully connected to our company network using VPN PPTP by following the guidance in Pogue's Missing Manual. The VPN window reports that I am connected to ip 192.168.0.150 which our network guru tells me is the address of the "Internal virtual network adapter on the VPN." The actual server PC with the data on it is at .100.
Now, he's a great guy and everything but is definitely a Microsoft man only. When I asked him how to browse our network files on the server he told me to set up a network share using Windows explorer.
So..can anyone please advise how I can translate that action into OSX land? I have searched the Apple support papers but with no success. These days most hits for VPN concern the blessed iPhone....
I have tried in the finder running connect to server and typing in smb://servername. That returns error code -36 "the finder cannot complete the operation because some data in [that address] cannot be read or written". I have tried using the company lan IP address for the server instead and that returns "name or password is not correct".
I appreciate these things often depend completely on the fine details of our setup. If nothing else, does anyone know a good book to assist here - Pogue is a great basic guide but not really detailed enough for this sort of thing. Failing that, how do I find out what error -36 means? Ta.

Accessing a Windows Sharepoint 2003 Server

I recently upgraded my work Mac to Leopard with the latest updates etc. Since upgrading to Leopard, I have lost all access to our companies sharepoint servers - which are 2003 by the way. I can see them in the Browse area, I can get as far as entering my username and password, and click connect, but then it either just fails or reverts back to the drill down level I was on before.
I brought my Mac laptop in, and connected it to the same Ethernet network connection, using Tiger, and Woo Hoo, it works!
After a day on the phone to Apple support, I got the impression they were trying to make out that it is something with our servers that are at fault, and not anything to do with leopard. i am 100% confident, it IS Leopard, but Apple dont seem too concerned.
If you search online, many people have the same problem...
Does this now make apple wonder if there is a bug with this....

I upgraded to Leopard yesterday, and the first issue I've noticed at work is that trying to access our Sharepoint MOSS 2007 site causes Safari to crash. Firefox accesses sharepoint no problems. I also had no problems accessing our sharepoint site using Safari 3 on Tiger 10.4.11 prior to upgrading.

How can I connect 10.4 Mac to Windows Small Business Server 2003?

I have seen some other discussions touching on this topic and have tried the various solutions but am getting nowhere. I can't connect my iBook, which is running Tiger, to our office's server, a Windows Small Business Server 2003. I am the only Mac user and as a Mac devotee actually spent my own hard cash for the iBook. (I work for a non-profit with low funds.) Previously, when our office had a different server and I had Panther, I could access the server. Then it was purely an academic exercise, since I had no need to access the shared files. Now I have a project that requires this, and I am stumped. Our part-time IT consultant is also stumped. We have tried a lot of the suggestions from other posts, to no avail. I suggested to the IT guy that there could be a problem regarding the encryption of my password, and I think he tried that. We have tried various versions of the domain name. The server comes up in the list when I follow the "go--connect to server--browse" path, but we come up empty. We've gotten error message -36, a message that we are trying to connect an alias to something that can't be found, and a message that we don't have enough information to go any further (something like that). I am writing from my eMac at home, so I can't reconstruct the situation right now. I have found in my extensive internet search that Thursby has something called ADmitMac that is pretty expensive software ($119 for one person) that I could install on the iBook and could help me access the Windows Small Business Server 2003 without doing anything else to the server. Does anyone know if that would that work? Any suggestions would be so appreciated!
eMac and iBook Mac OS X (10.4.4)

I have specific errors listed below:
Actually, I have been encountering similar problems. I have an end user who wants to connect to an SBS 2003 server, and can not connect/use RWW because the Active X will not work, cannot use the VPN in PPTP mode because Windows 8 disallows the connection
("Error 942: The connection could not be established because the authentication method used by your connection profile is not permitted for use by an access policy configured on the RAS/VPN server."), and cannot use an L2TP VPN connection because it requires
a certificate "Error 766: A certificate could not be found. Connections that use the L2TP protocol over IPSEC require the installation of a machine certificate, also known as a computer certificate.". I attempted to utilize the SBS Connection Tool downloaded
from RWW, but it fails with a proxy error ("Unable to execute custom script (Configure proxy settings for IE). Required file could be missing." - likely due to the PPTP tunnel it tries to use). I went so far as to install the Enterprise CA on the server, installed
the Hotfix
(KB922706) so that the website could be accessed from Vista and above, and installed the requested certificate. The VPN fails to connect after
it times out and fails to negotiate a connection. This last one is "Error 789: L2TP connection attempt failed because the security layer
encountered a processing error during the initial negotiations with the remote computer."
I have screenshots to share if anyone cares to see. I really just get the feeling that Microsoft is trying to kill SBS 2003 by ingoring it into oblivion.
The VPN works fine with Windows 7 clients by the way.

Windows 2008 R2 server unable to browse UNC shares

Hi All..
I appreciate if anyone could assist with pointing me in the right direction. I have a 2008 R2 server which operates as our SCCM server. For some reason, in the last few days has lost the ability to browse UNC shares from itself, to any other host on the
network or it's own local shares.
DNS resolution and WINS both are working correctly. The affected server can ping any other host on our network, via IP and host alias or FQDN.
For purposes of trying to rule the problem out, I have tried combinations of disabling all WINS and NetBIOS settings on the server, simply in an attempt to see if the issue was DNS, WINS or NetBIOS related. In all cases, attempting to browse another host
using the UNC share , i.e. <\\hostname\sharename> or <\\host-ip\sharename>
Doing a net view \\localhost or net view \\remote-server returns the correct list of shares. When trying to map a drive via net use x: \\remote-server\share I get;
System error 67 has occurred.
The network name cannot be found.
And when browsing via Windows explorer I get the message
Error Code: 0x90070043
The network name cannot be found
The same results happen for netbios name, FQDN and IP address.
From the other side, every other host that I've tested can access shares on the the affected server. (I've tested XPSP3, WIN7 64-bit, WIN2003 32-bit, WIN2008 & WIN2008R2 hosts)
I have also tried a "nbtstat -a <remote-hostname>" and "nbtstat -a <remote-host-ip>" and the information returned corresponds with the WINS server details.
I have also tried an "nbtstat -S 2" whlist attempting to open a UNC share, but no corresponding entries appear while attempting to UNC browse.
I should point out that the error notification (of the failure to connect) is instantaneous as if the server isn't even attempting to try going remotely. (i.e. no timeout) Which leads me to thinking there's a configuration setting somewhere that's causing
this problem??
There are no 3rd party firewalls installed, the windows firewall service is started by default but all the profiles for the firewall are turned off. We have tried setting firewall to on and allow all traffic, but the problem remains. All ports are open inbound
and outbound as I can telnet to ports 139 and 445 of other servers from this server. I have also tried enabling all netbios rules that were disabled on the windows firewall (in order to rule out any potential conflict).
The server was running Sophos 9.7 AV, I have tested completely removing the AV software from the server in order to rule out any potential conflict. This did not resolve the issue.
I have also verified that it's not down to a disabled computer domain account.
The servers are only operating IPv4, and obviously have File and Print services enabled, and client for Microsoft Networks.
The AD domain was upgraded, many weeks prior, from an AD2003 domain to an AD2008, and the server was operating as expected until I discovered that the UNC shares were no longer working on this affected host.
While it is not affecting config manager clients connecting to the server, is has an impact if a SCCM task sequence needs to retrieve data from a UNC share.
As mentioned the server is a 2008 R2 box, it's a virtual machine operating on ESXi 4.1U1. The OS is fully patched and and VMware tools are up to date. The server is a member server of our AD domain. We have many other similarly configured 2008 R2 servers
operating on the same ESXi host; in fact we have 2008R2 hosts acting as SCOM, SCOM RMS and SQL2008 R2 servers. All these servers are operating on the same IP subnet. All of these servers are operating with the same network configuration (with the exception
of different static IP addresses).
We have tried removing and reinstalling the VMware tools, and removing and reinstalling the Intel NIC, this hasn't made any difference either. I have also tried changing from the Intel NIC to a VMware VMXnet NIC. This has not made a difference.
Any suggestions would be really be greatly appreciated as I've not been able to solve this to date..I will gladly supply any additional info if it can help anyone in the future, should they come across this problem.

Hi,
Just giving this thread a bit of a bump on this thread as I'm still trying to figure this one out..
I did resort to restoring from backup, to get my server working, but I'm encountering the issue on another 2008 R2 box, which is not good. So any suggestions you can think of would be appreciated. I think that this issue is more of a network protocol related
nature, rather than application issue.. I'd appreciate if anyone could suggest how to proceed further on this one..
Below are two snippets of wireshark captures, one is between the affected 2008 R2 host & a windows 2003 server, and the second one is between a working 2008 R2 host and the same 2003 server (used in the first example). In the test examples, I am simply
doing a start -> run; then typing \\2003servername\ and pressing enter. Below is the network traffic between the two hosts, after I hit return;

I can reproduce the same network traffic against 2008 R2 host, only the SMB traffic will show as SMBV2
TEST#2 - To compare this, I ran the same test (above) using a working 2008 R2 host, against the same 2003 remote server. You will see that it is considerably more network traffic, than the above
failed example.

Again, I can repeat the same test against a 2008 R2 server, and I will get the same output, except the SMB traffic will be SMBV2
It appears to me that the issue is protocol related, as you can see in test#1 between the second-last and the last line of network traffic, it jumps from "STATUS_BAD_NETWORK_NAME" to a TCP/IP [ACK] response. Yet in
test#2 you can see that after line 336 (shown below), you can see it calls "wkssvc", which I'm assuming is the workstation service.. which we don't see at the first (failed) test..

SBS 2008 - Windows 8.1+ clients trouble accessing file server shares

I have now upgraded 1 Windows 8 machine to Windows 8.1, and also clean installed another with Win 8.1 update 1 today, and both machines have trouble accessing the SBS2008 file server shares by UNC. If I browse by IP address of the server it seems to work
flawlessly. The odd thing is that it's sporadic. So if I browse in explorer to "\\*netbiosname*\share" the Win8.1 machine will sometimes be able to access the share, and other times it will fail with a "network unable to reach location etc.."
error. When it does work, it can take up to 5-10 minutes while explorer is frozen before the share is accessed. We're running quite a few Windows 8 machines without a problem, but it seems to be a specific problem with 8.1. Any idea?

This doesn't seem to fix this specific problem. I had a few days of "luck", but now it's back. I just upgraded another co-workers machine to Win8.1 and he advised me that he's been having the same problem even with the above fix applied. His issue
is when opening an office document that's located on the file server using location "\\servername\filename.xlsx", it takes a very long time (minutes) to open the excel file. This was happening to me as well, and if I tried to browse the network during
this period, Windows Explorer would sometimes give me path not found, and unspecified error. I will try and capture a screen of the error when it occurs. Any ideas??
edit: I have also noticed an unresponsive Windows Explorer for a few seconds to a minute over the last few days, which is a pretty good indicator that it's still happening on my machine.
The odd thing is, if I use the IP address of the file server, everything is fine. I changed all of my links to use the IP since October when Win8.1 was released to combat this problem, and only changed them back to the server name for testing since I want
to start deploying Win8.1 to others in the office. Unless I can fix this bug, they'll have to be stuck on Win8.
Thanks,

I am trying to allow guests on windows to connect to shares on my Lion server but it keeps asking for a password for guest. I have allow guest users to access this share enabled but it still does not work.

Ditto. Guest accounts shouldn't have a password. No way to enter one in System Prefs...

Trying to access Windows 2003 Server share with Mac OS 9.04

Hi
I cannot connect to a Windows 2003 Server share on my 2003 domain. I can access the share with my MacBook (10.4.9) & my G4. I have File Services for Mac installed & can ping the server from all OS 9 Mac.
Can anyone give me some tips?
MacBook Administrator

How are you trying to connect to the server? Via AppleTalk or IP? (What utility are you using to ping the server from the Mac OS 9 machine?) Since you're not providing any information about error messages you're receiving or the symptoms of your problem I can only provide the following information.
If you're selecting the server from a list in the Chooser and clicking the OK button then the connection should switch to IP automatically. Make sure your Mac has TCP/IP enabled and is receiving an IP address or that you have an appropriate IP address hard-coded. You can try forcing an IP connection by entering the IP address or DNS name of the server in the Chooser rather than selecting it from the list in the Chooser.
Or you can try forcing an AppleTalk connection by selecting the server in the Chooser and holding down the Option key as you click the Connect button. If you're asked to enter your name and password then you're communicating properly with the server. This is, however, a very slow connection compared to IP.
Finally, be sure you update to the latest version of Mac OS 9, which is 9.2.2 <http://docs.info.apple.com/article.html?artnum=75288>.
Hope this helps! bill

\\?\UNC\server\share - verylongpath errors out

In Windows Explorer the UNC long path construction errors out as:
Windows cannot access \\?\UNC\server\share
(Error: 0x80004005)
Background:
https://msdn.microsoft.com/en-us/library/windows/desktop/aa365247(v=vs.85).aspx
To specify an extended-length path, use the "\\?\" prefix. For example, "\\?\D:\very long path".
The "\\?\" prefix can also be used with paths constructed according to the universal naming convention (UNC). To specify such a path using UNC, use the "\\?\UNC\" prefix. For example, "\\?\UNC\server\share", where
"server" is the name of the computer and "share" is the name of the shared folder.
What am I missing here? The UNC prefix never worked for me.

Hi,
It is a Windows explorer restriction (MAX_PATH). Windows explorer is different than the file system for its API. If you prefix the file name with "\\?\" and call the Unicode versions of the Windows APIs, then you can use file names up to 32K characters
in length. In other words, the \\?\ prefix is a way to enable long paths while working with the Windows file APIs.
If you need to use the out-of-length type file in Windows explorer, your need to make the name shorter to remove a file like this from the server itself.
For more detailed information, you could refer to the Microsoft support answer in the thread below:

Active Directory, Windows 2003 SP2 Server and SMB shares

I have 10 new iMacs that will be returned and exchanged for 10 HP wintels if I can't resolve an issue with SMB shares in Mac OS X 10.4.9.
We had an old win 2000 server, and all the macs could mount their smb shares without problems.
Recently we upgraded to two new 2003 sp2 servers, one of them the domain controller, and we can't mount their SMB shares. I followed this http://weblog.bignerdranch.com/?p=6&page=3 and/or this http://allinthehead.com/retro/218/accessing-a-windows-2003-share-from-os-x to allow AD authentication, but still, I can't mount the 2003 shares (but can with the 2000 ones!!!).
If I enable SFM (services for macintosh) then I can mount the shares, but:
1) the network is slower (I supouse is due to appletalk implementation)
2) and worse, names with more than 32 characters or with some special characters are not allowed. This renders 30% of our archives unavailable with the AFP solution.
I also used all the authentication methods (Plain text apple, plain text windows, etc.) but no one works.
I have now 10 days to find a solution, or all "my" macs will dissapear forever.
Please, some advice or point to documentation.
G4, G5, iMac Intel, Mac Book Pro, etc Mac OS X (10.4.9)

Do you just want to mount arbitrary share from the win servers or do you want the macs to be bound to AD?
The first requires the steps from your second link (allinthehead.com) but the latter (bind to AD) requires things like proper use of DNS, time synchronisation for kerberos to work and proper configuration as described in your first link (bignerdranch.com).
Here are some more links for the latter (AD intergration):

Mac OS X and Windows Storage Server share

I have a new Windows 2003 Storage Server and several MacBook Pros. I created a share on the root of a drive on the Windows server. I get the following error when trying to copy a file to the share: "The operation cannot be completed because you do not have sufficient privileges for some of the items".
If I create a folder on that drive and create a share with the same permissions, the file copies with no errors. Also, the only way it works is if I give permissions to "Everyone".
I'd like to lock the permissions down to a group. Any ideas? Thanks!

Adawgalicious -
Welcome to the world of Mac/Windows integration. I too get rather frustrated when trying to get the two systems to work together (I have thought of having my systems watch the Apple ads - in hopes that they may remember that they supposedly work together).
Seriously - I have my iMac as well as an Ubuntu server talking to my Windows 2003 Server and Domain. A few questions:
- Are you joining the Domain with Macs?
- What version of Leopard are you using? 10.5.5 and .6 seem to misbehave at times.
To work around my problems I joined the Mac to my Domain using the Directory Utility. Once I did this I was able to connect to any of the shares within the Domain. I am able to create folders on the Windows share using my iMac and access them on my Windows systems (you will need to have a Domain account to connect tot he shares).
Best of luck -

Server 2012 R2 SMB - The process cannot access the file '\\server\share\test.txt' because it is being used by another process.

Hi,
We are having issues with Server 2012 R2 SMB shares.
We try to write some changes to a file, but we first create a temporary backup in case the write fails. After the backup is created we write the changes to the file and then we get an error:
The process cannot access the file '\\server\share\test.txt' because it is being used by another process.
It looks like the backup process keeps the original file in use.
The problem doesn't always occur the first time, but almost everytime after 2 or 3 changes. I have provided some code below to reproduce the problem, you can run this in a loop to reproduce.
The problem is that once the error arises, the file remains 'in use' for a while, so you cannot retry but have to wait at least several minutes.
I've already used Process Explorer to analyze, but there are no open file handles.
To reproduce the problem: create two Server 2012 R2 machines and run the below code from one server accessing an SMB share on the other server.
Below is the code I use for testing, if you reproduce the scenario, I'm sure you get the same error.
We are not looking for an alternative way to solve this, but wonder if this is a bug that needs to be reported?
Anybody seen this behavior before or know what's causing it?
The code:
string file =
@"\\server\share\test.txt";
if (File.Exists(file))
File.Copy(file, file +
".bak", true);
File.WriteAllText(file,
"Testje",
Encoding.UTF8);
The error:
System.IO.IOException: The process cannot access the file '\\server\share\test.txt' because it is being used by another process.

Hi,
There is someone else having the same issue with yours. You could try code in the article below:

Windows 7 Client 'sees' an old version of windows 2012 server share

Hi All,
I have a problem which seems to be a common theme looking at other threads. Here's the overview of the problem:-
I have multiple windows 7 clients and a windows 8.1 client within a 2008 Server in a domain.
I also have a Windows 2012R2 Server which is not joined to the domain. There is a Share on the 2012R2 which has the Caching Option turned off. Everyone full control on Share & File permissions.
One of the Windows 7 machines in Explorer when it looks at
\\2012server\share sees an old version of the folder. It seems that SMB 2 chaching is working too well. Not even pressing F5 or clicking View, Refresh updates windows explorer.
It took a reboot to get the workstation to see the up to date contents of the share on the 2012 server.
We don't seem to have that behaviour with that client against the 2008 server.
I have seen this behaviour on another machine un-related to us at another location which was in a workgroup with a 2012 server and no domain.
Questions:-
Is there some sort of problem with Windows 7 workstations working against 2012 Servers in a non-domain setting or is it just Windows 7 against 2012 servers period?
I understand that Windows 7 utilises SMB1 & SMB2. SMB2 introduced caching. If the server has turned off the share cache option should the client cache the contents of the share or the information about the files & folders & 'file not found'
information?
I want to open a file handle to a file on a network share so I can read and write data to it. But I also want to know that when I look at the folder to open the file I'm actually looking at the live version of the folder and files in the folder and
not a cached version of the folder. If it's a cached version the file might be there already but I won't see it.
Is there an API call that tells the client to get a fresh view of the server share so I can be absolutely sure that when I look for a file on the server I'm getting the correct answer and not one from cache.
I first posted the question with the same subject "Windows 7 Client 'sees' an old version of windows 2012 server share" in the Windows 7 Networking Fourm
https://social.technet.microsoft.com/Forums/en-US/23bf3627-987b-4c27-8062-85a284a2cda4/windows-7-client-sees-an-old-version-of-windows-2012-server-share?forum=w7itpronetworking and it was suggested I repost in here. Please do take the time to read
the thread which will save time with suggestions that have already been covered.
As the computers that can be affected by this problem are not mine I cannot enforce or guarantee that any of my 'client base' will apply any hotfixes. I will also not have the ability to tweak registry settings as I can't guarantee Admin Access.
It seems that we need to go back to SMB1 as all the tweaks to SMB since those days have introduced problems with the basic requirement of sharing files from a share on a server for Read/Write purposes. I have tried turning a network back to SMB1 and that
has resolved a lot of the issues but then I found a post/MS blog that states not to leave the network on SMB1
The Caching option of the share had already been turned off. Surely Windows clients should not cache any information about the share but I think that is not the case.
Thanks is advance
Robert

Hi Shaon,
Thanks for looking into this.
If this is a known issue, why isn't the hotfix rolled into a general windows update if this is a known problem? However this doesn't just affect domain joined workstations.
Surely it's basic functionality for a networked computer to access files and folders on a network file server. It's what networks were invented for at the end of the day.
I am unable to apply hotfixes to these computers that are having the problem due to the fact they are not mine but my customers.
At one of my customers sites I disabled SMB2 from the server and network clients as well as disabling the network adapter power saving option. This seemed to resolve the issues that I saw on one client that seemed to be 30 minutes behind the rest of
the network. The hotfix you link to states that it is for Domain joined computers. At my customer site the PC's are not in a domain at all, just a workgroup with workstations and a 2012r2 server. Will the hotfix be applicable to non-domain machines?
Also many clients seemed to loose the file handle to an open file on the server. I'll get them to turn SMB2 back on at some point after I send out some updates but all the problems I see seem to be caused by the caching functions in SMB2. SMB1 is good and
stable. It's SMB2 that seems to be causing the problems as it was designed from the ground up for caching.
Has this networking issue been resolved in Windows 8, 8.1 and 10?
As I am unable to apply a hotfix to 1000's of PC's that are not mine, is there an API call or something where I can get the windows client to stop lying and get me the current state of a folder on the server?
Will Turning off ClientSideCaching fix the issue? HKLM\SYSTEM\CurrentControlSet\Services\MrxSmb\Parameters\
CSCEnabled
Or will every machine need to be tuned individually according to the following guide:-

I would like to share my ipad on my Windows machine. I got the Ipad to HDMI adaptor but nothing is displayed on the screen... Do I need any additional softwares?

I would like to share my ipad on my Windows machine. I got the Ipad to HDMI adaptor but nothing is displayed on the screen... Do I need any additional softwares?
Actually I would like to have the Ipad connected to pc and then run an application on the ipad (which is shown on my windows machine) and record it on the windows machine... Is this feasible?

If you have an HDMI connection on your computer, it is most likely an output, it won't recieve a signal unless it's on a video capture card. Recording to the PC could be a difficlut task. HDMI is encrypted to keep you from copying but there are ways to do it. It would also depend on what content you intended on recording. If it's movies you have purchased or rented, it would be illegal.

Access unc windows shares like \\server\share\
