Cannot access the shared folder

Question

There is a shared drive in our university where anyone can share files. I had mapped this as a network drive on my computer earlier but cannot access it anymore. I am using Windows 7.

When I put the given IP (\\10.3.20.20) in run command, it says Windows cannot access \\10.3.20.20 with the Error code: 0x80070035

Success

1. Everyone else can open it easily
2. I can ping it
3. I can open it in WinSCP
4. net view \\10.3.20.20 works fine (shows Samba Server Version 3.0.33-3.7.el5) and gives the list of all folders in it
5. I can open it from Windows XP installation from the same computer
6. My browser works fine

Error

1. net use \\10.3.20.20 returns System error 53 has occurred.
2. Tried opening this from run
3. Tried opening it in explorer
4. I tried to map the network to a drive I got the same error message.
5. Tried accessing a folder on this location
6. I have turned off my firewall and anti-virus, this didn't help.

I live in a hostel, onsite of a university campus, and I'm trying to connect to my uni computer from the hostel. It is here where it fails. I cannot connect to the shared folders on my own workstation within the university from the hostel!

I can RDP into the workstation.

Solution

I have done some research and this article looks the most promising. I've copied the relevant part over.

Browse to "Local Policies" -> "Security Options". Now look for the entry "Network Security: LAN Manager authentication level" and open it. Click on the dropdown menu and select "Send LM & NTLM - use NTLMv2 session security if negotiated". Apply the settings.

In the Advanced sharing settings page of Network and sharing center, you need to have it set as Work/Home profile. Try:

-Enable network discovery
-Turn on file and print sharing
-Turn off password protected sharing
-Use user accounts and passwords to connect to other computers

The other settings such as encryption I have set as use 128 bit encryption.

Please check related policies.

1. Enter “gpedit.msc” in the Start Search box.
2. Open “Computer Configuration”/Windows Settings/Security Settings/Local Policies/Security Settings.
3. In the right pane, enable the following policies:

Network access: Allow anonymous SID/name translation Network access: Let Everyone permissions apply to anonymous users

Also please disable the following policies.

Network access: Restrict anonymous access to Named Pipes and Shares
Network access: Do not allow anonymous enumeration of SAM accounts
Network access: Do not allow anonymous enumeration of SAM accounts and shares

No I cannot open the IP from the explorer (run), how can I map a folder?

[LifeH2O]

Turned off firewall, Turned off Real Time protection of Security Essentials. Still getting the same error

As was able to map the drive and access it earlier, some service might not be working. But Computer Browser, Tcp ip/bios, Network, DHCP services are running fine.

The shared folder is there, everyone can access it. Only I am getting this error. This is a Wireless LAN. I have edited to make my problems clear. Can you please edit and make it more clear.

[LifeH2O]

We connect on wireless lan and there are many wireless networks available. Even if we are on the same network, we cannot ping each other as I just tried with a friend. No ping, no shared access. We are assigned a new IP each time we connect with a network. I have computer in Lab which I can connect with remote desktop. I shared a folder on it but can not access it from this computer.

Also I can still connect to 10.3.20.20 from my pc in Lab (I am in hostel)

[Dave]

Is it possible that the system administrator has altered something? Can you just double check that your friend can still access too?

[Dave]

What do you mean Also I can still connect to 10.3.20.20 from my pc in Lab (I am in hostel)? Also, it may be a good idea to delete some of your comments as I have moved them into the question for you

[Dave]

And lastly, do you only have an IP address, do you have a name of the server which you could try and connect to?

[LifeH2O]

I also have problem with some windows updates. KB2724197, KB2676562 and KB2679255 are not installing. They give the error code 800B0100. That might have been causing this problem

[LifeH2O]

The one in hostel.

[LifeH2O]

I have admin access to that system. I shared a folder from that system by connecting to it but cannot access from hostel. I am strongly thinking that those updates are part of this issue. I am trying to solve that.

[Dave]

Please try this tool: windows.microsoft.com/en-US/windows7/…

[Dave]

Or this tool, which will try and automatically fix the issue from Microsoft

[LifeH2O]

I am already trying all these. And other fixes from microsoft.

[LifeH2O]

I restarted the PC and still getting the same error. :-( Only browsing with explorer is not working, otherwise that network address is accessible.

Guy, this wasn't the case, the OP was just formatted badly (if you type \\ without the blockquote or code tag on the SU site it will format it and automatically remove one of the slashes. I have edited the OP and corrected it now.
