Windows 7 cannot access shared folders
Recently my windows 7 cannot access shared folders by ip \\192.168.128.11\shares Last night I was able to connect and access files no problem. I get an error code 0x80004005 unspecified error. My tests are as follows: I can ping the IP address. I can RDP into the computer. At the same time I have vmware on my windows 7 with windows xp as a guest os. From windows xp I can connect and access the files. After I use System Restore to the previous day my windows 7 can access the files. I don't make any changes and turn off the computer for the next day or two. When I power back on, windows 7 cannot access the share again. I did the same tests as previously stated with the same results I've been doing research for the last week and had to keep using the System Restore every day in order to access my share files. Any advice would be much appreciated. Thanks in advance,

Ensure the comp that you're trying to access are power on. Instead of mapping it's IP, try mapping the username instead as in follow \\BKUO-PC (example) Make sure the following feature is turn on, if is running win 7 1)network discovery 2)file and printer sharing 3)public folder sharing except 4)password protecting is turn off 5)home group connection=allow windows to managed home group connectionLastly ensure there's no third party firewall on both comp

Well I tried the suggested changes but windows 7 explorer still could not show the windows xp shares. I have a nas as well that too cannot be viewed from windows 7. I have a secured network so I do not have third party firewall installed.

Hi, Are the Windows 7 machine and the target machine in a domain? At this stage, I suggest you temporarily turn off firewall on Windows 7 machine and the target machine for a test. If the issue persists, please try following steps. 1: Clear the Hosts file -------------------------------------- a. Click the Start Button, type "%SystemRoot%\system32\drivers\etc" (without quotation marks) and press Enter. b. Right-click on the file "Hosts" (without quotations) and choose Delete. c. Click Continue to confirm the deletion and verify the administrator permission. 2: Clean up the Domain Name Resolution (DNS) cache -------------------------------------- a. Click the Start Button, type "cmd" (without quotation marks), in the search result list, right click on Cmd.exe and select Run as administrator. b. Click Continue button to verify the administrator permission. c. In the popup window, type: "ipconfig /flushdns" (without quotation marks) and press Enter. If the network folder still cannot be accessed, please collect the following log file when the symptom occurs. Collect the Netmon trace ========================= a. Download NetMon3.3 from the following website and install it on the computer http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=983b941d-06cb-4658-b7f6-3088333d062f b. Launch NetMon3.3. c. In the Microsoft Network Monitor 3.3 window, click Create a new capture tab … d. In the new tab, select all the Network Adapters in the Select Networks window. e. Then, switch to Network Monitor, press F5 to start NetMon. f. Try to download the large file. When it failed, go to step 7. g. Go back to the NetMon window and press F7 to stop the NetMon. h. Press Ctrl+S to save the Netmon file named test. i. Then, please upload it Thanks, Novak

http://cid-d938941bf24b9cc7.skydrive.live.com/self.aspx/Capture/test.cap I've look at the file too. I can see the ipv4 patches from 192.168.128.69 to 192.168.128.10. It's sort of Greek to me.
January 15th, 2010 7:49am

I also capture the one to 192.168.128.11 http://cid-d938941bf24b9cc7.skydrive.live.com/self.aspx/Capture/testb.cap Ping and tried to browse through windows explorer.

I've captuerd from one of my guest vm computer, that's on the windows 7 computer that has the problem. I was able to connect with no problem.http://cid-d938941bf24b9cc7.skydrive.live.com/self.aspx/Capture/test%5E_good.cap

Hi, After analyzing the log file, I suggest you perform a Clean Boot to check the result. Thanks, Novak

Clean boot also has the same problem, only the Microsoft service was enabled. This time the error message came back a lot faster. I've tried to diagnose from cmd and at least try to ping, and I couldn't ping "unable to contact IP driver" . I'll tried to stop all services and try to see if one service is having the problem.

Ok, I gave up and used the windows 7 dvd and upgrade/re-installed. It kept all my existing programs and now getting to my share on the network works. For sanity check I've capture my network traffic. http://cid-d938941bf24b9cc7.skydrive.live.com/self.aspx/Capture/test%5E_20100117.cap I see the big difference where the SMB is now in the packets captured. Is there a way to replace/repair the SMB service if it fails? Thanks, Bkuo

Is there a way to replace/repair the SMB service if it fails? Thanks, Bkuo Hi everybody, I have the same problem today and I think the issue is related with SMB over TCP. I'm looking for some information about how to restore SMB or how to fix this problem, but i didn't find something to help. I captured the network connections using NetMon and there are not SMBoverTCP instances in my Win7. So, anyone could help me to restore the smb service? PS: My win7 is x64 and all others machines in my network are win7 x86, and only the win7 x64 had this problem (two times) - Are there any related information about this issue with x64? The first time that it happens, I re-installed everything, but now I want really fix it. thanks in advance Guilherme Rattes

Welcome to the club. I'm having the same problem and have been researching it all day. Try this out: create a folder called "test" on your C drive and share it. You'll find out you can't access it by using \\computername\test There is definitely an OS issue at work here.

I have the same issue, it was working fine for the last month now it won't let me access the Windows server at all, keeps telling me "wrong username or password" I do a system restore to the day before and it works fine for a while then the problem returns. Thought maybe a Windows automatic update was to blame so I did another system restore to the prior day and disabled automatic updates and I had access again. Then an hour later same issue. Come on Microsoft what is the deal!!! We need a fix for this.

I am having the same problem with some Vista Business machines too. I see there is no solution to this other than rebuilding/reinstalling windows. There is also no solution in other forums. I wonder if Microsoft knows about this. There is no report or article on this in Microsoft web site too. I have raised another question thread on this with Vista in the title to highlight that this is not just happening to Windows 7. Regards, ltkhoo

Hello, I believe I am having the same issue. can you please post a link to the fix in the vista forums? Thanks!

Ok, this did the trick for me. I had to do some software debugging and testing with different dates and changed it a couple of times manually. Suddenly I could not access network drives anymore. After I changed it back to the current date, the problem was solved. I really don't understand what the data has to do with validating if your password is correct or not but I am happy it's working again.

I've had the same problem for a long time... tried everything... blamed win7 x64, because i have a laptop running win7 x32 ultimate and no problems accesing shared network folders on that... but... i have eset smart security, maybe i dindt configured the network correctly when i first accesed the wifi with the x64 computer... it was the firewall!!! dahh.. seemed so obvious once i had it working.... disabled firewall on eset and it worked, later i realized what was wrong, enterd advanced setup, went to firewall and fixed to trust my wifi network, that was it! it will work, try it on your antivirus, or windows firewall... i've disables windows firewall and only have eset's firewall on... if you allowd sharing when you first added your wifi, you're set, no problems there... the problem starts when adding the wifi to the computer, if you selected "do not allow" sharing and when windwos pop's up asking if its a home/work/public network, you select public, your're screwed... for trusted networks, select both on antivirus firewall and windows network: trusted/home, allow/home, or whatever term your antivirus uses... cheers!

Thanks SSVEERESH, I tried that previously, and the problem still exists. Here's some more info that I found on my problem: If I try to ping the server from the CMD from a client computer by host name, e.g. SERVER-PC, it fails.I then ping the server by IP address, it works.I then try to ping the server by Hostname, SERVER-PC, and it works. Any ideas? dmatranga

I had a similar problem like this Dan. Are you using Hyper-V or VMware by any chance? Because that's what caused the issue for me - Hyper-V created a virtual network connection which messed up the physical NIC local area connection.

Actually, I do have a LogMeIn installation on the server computer so that I can access it remotely. Could that be creating some issues you think? And can I not have the best of both worlds, i.e. LAN access and Remote Access? If not, let me know what you did to remove the virtual network. Thanks, Dandmatranga

Hello, have encountered the same problem - none of the proposed fixes in the www work. http://social.technet.microsoft.com/Forums/en-US/w7itpronetworking/thread/6c5069d3-826e-4b56-b78a-4a51239abf81 My IP Network works fine, but accessing shares of other computers does not work anymore. Before asking for user/password the unspecified error 0x80004005 appears. Maybe someone can tell how to re-install all network protocols from LanmanWorkstation and all the rights handling instances above. Any help welcome.

I have a Windows 7 ultimate that cannot access any file shares on my network, either by name or IP address. This was working and I have followed all the suggestions from the NTLM, to removing ALL my networking components and reinstalling, to disabling Windows Firewall to removing my antivirus, and I am unable to system restore back to when it was working. Please Microsoft, this seems to be a fairly widespread issue, please help us!!!
May 23rd, 2012 5:18pm

It got resolved after installing Client for Microsoft network which was not present in the network settings.

I had the same issue between two Windows 7 Ultimate computers, with advanced sharing enabled. I disabled IPV6 on the sharing PC, and can now access the shares form the other one. BR, B BalintN It was only a temporary success: after restarting the sharing box, I can't access it again, I get an Access denied error. :-(

Check Credentials on Windows 7 machine. I found the credentials were for local machine. I edited to Domain\User with the user password for the domain and this worked. A reboot will be required. You can access credentials in control panel.

Hi All Finaly we found the solution here 1. Start Registry Editor. To do this, click Start Collapse this imageExpand this image , type Regedit in the Search programs and files box, and then press ENTER. 2. Locate and then click following registry subkey: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\LSA 3. Locate the LmCompatibilityLevel registry value. If the registry value is not present, follow these steps to create it: Select the registry subkey that is listed in step 2.On the Edit menu, point to New, and then click DWORD Value.Type LmCompatibilityLevel, and then press ENTER. 1. Set the DWORD value to 1. To do this, click Modify on the Edit menu, type 1 in the Value data box, and then click OK. 2. Exit Registry Editor and restart the computer. Was is same boat as most users here, had tried everything, repeatedly, except the quoted. This worked! After applying the registry edit, I rebooted. It didn't work straight away. I ran an elevated CMD.exe and rebuilt the mapped drive as follows. net use \\[server]\[share] /user:[username] [password] /P:Yes and that was that, it worked. Running Vista Home Premium SP2 This has been infuriating for me, can I ask exactly what that registry change did? I was in the same boat, where from the vista client I could see all shares on the server, but could not access any despite EVERYTHING being setup correctly on both ends. Every other client could access the shares with the same credentials. The Vista client could access shares on every other client correctly, just not the server. Also had a virtual enviroment setup on client pc with virtualpc and also a logmein user.
