Suddenly cannot map drive over VPN - any clues please??

[hztm2]

Hi, this is my first post and I would be so grateful for any advice.

I have windows 7.
I can VPN to our office ok, I can RDP to any of our servers ok, I can open outlook and it connects across to the exchange server ok BUT I cannot map a drive to any of the servers (Windows cannot access \\xxx.xxx.xxx.xxx\myshare - error 0x80070035).

I have various VPN's to various customers and all are now failing in the same way.

Everything was working fine - I could connect to any network and map to drives, but suddently it all stopped working. This happened to me back in January and I ended up rebuilding the machine and that fixed the problem. Now it has gone again and I really do not want to have to rebuild the machine again - there has to be a reason.

Thanking you for any assistance.

The observations where as follows:
1. The host pc is picked up on the comp
2. When selected it produced the following error: 0x80070035 network path not found
3. I tried various options such as ticking the TCP/IP and enabling all the possible options available under network connections properties.
4. This still produced the error although the host computer is pinged

The solution was simple:
I was running NORTON 360.
Under firewall settings; disable personal firewall.
Once this is done, access is allowed to the host pc.
You can then set your permissions, create network paths and map network drives like you would normally do.

Hi, thank you for the advice. I have already tried disabling the firewall and anti-virus software but the problem is still there.

You will have better luck if you uninstall the A/V and firewall completely.

Test this:

I had two Windows 7 machines, A & B. A could see B and share files well. B could see A but when I'd click on its icon I would get the 0x80070035 path not found error.

I could ping A from B via IP address but not name, so my gut feeling told me this was a DNS problem.

I used Start > Notepad. On the results, right click Notepad and "Run as administrator". Open C:\Windows7 (or whatever your root is)\Windows\System32\drivers\etc\hosts

In the file, toward the bottom, add a line with the IP address and name of the machine you are trying to reach. For example, 192.180.0.123 MachineName leaving at least one space between the number and name. Save the file then close Notepad.

I then Windows+R and CMD. ipconfig /release followed by ipconfig /renew. Then ping MachineName and you should see it work. Open Windows Explorer and you'll now have access to your other machine's files.

I can't explain technically what is happening. It appears that the part of Windows that should be updating the hosts file is not. If you do it manually it works. Remember, you have to open Notepad as an Administrator or you can't save the file.

Hi, thank you for the info. Unfortunately this still does not work. It is really strange - I can ping the server, take remote control of the server (RDC), connect outlook to exchange on the server - but I cannot map a drive. Tried two other VPN's and different servers - exactly the same issue. Thanks

hztm2, open your server's firewall configuration - look for "File and printer sharing" rule that's applied to the network interface (watch the profile), make sure it's not limited to "Local subnet".

Hi, thanks - I am using the inbuilt firewall and it all appears to be correct. I also still get the problem if I disable the whole firewall. I think I am going to have to rebuild the machine - Thanks

 

[zzz2496]

Hmm... you love to rebuild, eh? Good luck then...

[hztm2]

No I hate rebuilding - I have found various other posts on the web about this which seem to relate to Windows 7 beta and RC. I am going to log this with Microsoft tomorrow.

You sure the firewall rule doesn't limit the scope to "Local subnet" only? If it limits to "Local subnet", then there you have it, you need to set it to "Any IP addresses".

Hi zzz2496 - thanks very much for your assistance - I cannot find anything wrong in the firewall (compared settings to another machine that is working). However, I have found the following error in the system event log everytime I connect to the VPN

Initialization failed because the driver device could not be created. Use the string "000000000100320000000000D71000C011010000010000C008000000000000000000000000000000" to identify the interface for which initialization failed. It represents the MAC address of the failed interface or the Globally Unique Interface Identifier (GUID) if NetBT was unable to map from GUID to MAC address. If neither the MAC address nor the GUID were available, the string represents a cluster device name.

NetBT - Event Id: 4311

Yesterday I was onsite at a clients premises and connected to their wireless network - everything was working and i could map drives. Today I am back on my own network and it is not working - I cannot think of anything else that has happened apart from moving across different networks.

Once again, thanks for your help, very much appreciated.

So strange, contact your internet company, and tell them to come over and help you.
Or maybe it's something the router or what u know have. Try to enter the router and look there
