Windows 10: Windows 10 laptop cannot access network computers

Windows 10 laptop cannot access network computers

Network setup: W10 laptop(Home, v1607 but problem was even before v1511) connected via either Ethernet or wireless to a TP-link MR3420 router( firewall disabled). W10 tablet (Pro, v1511), wireless. W7 desktop Ethernet connected. Internet is provided via a separate LTE router connected to the TP-link. Buffalo NAS LS220 connected via cable to TP-link.

Problem: cannot access other computers or NAS on my home network from my w10 laptop (L: \\COMPUTERNAME or L: \\IP-address makes no difference). Also, The laptop itself cant be accessed from other computers. Other computers can see the laptop but generate 0x70080035 (windows cannot access...) when I click on the laptop. The same happens when trying to access other computes from the laptop. The laptop can see the tablet but not the W7 desktop. If I enable/disable SMB1 in the NAS, or create a new folder in the NAS, I can sometimes get the NAS visible from the laptop until next reboot, however I can never browse the shared folders. This was possible from the laptop a few weeks ago before the problems started. There has never been any problem to access the webGUI:s for the router or NAS from the laptop. The tablet, W7desktop & NAS has no problem accessing each others folders.

I have spent many days on this and lost track of all suggested fixes & registry hacks that I have tried without success, but below is a list of some things tested:

Enable network discovery/filesharing disable password protection...etc advanced sharing page, tested all settings.
Reinstalled all network cards
Enable Netbios over TCP-IP
Adding a new local user account
Setting Full Control for everyone for a shared folder
Changed L: \\COMPUTERNAMES to CAPS
Client for microsoft....is installed in TCP-IPV4
Disabled windows firewall
Blocked incoming port TCP139
Turning NAS/desktop/laptop on/off in different order (NAS become master browser if turned on first, if not W7desktop. The laptop does not seem to be able to take the role of master browser).
Removed homegroups from all computers (laptop cannot join homegroup and other computers cant join homegropup on laptop)

I'm just about to give up and make a clean install of w10 on the laptop, not looking forward to that with 300GB to back up without access to my NAS...

Thanks in advance for your help and suggestions!

Edit1: After performing a "network reset" from windows settings network&internet/status, the laptop can see all the other computers but still cannot browse them (can't access....).......And after a reboot, only the W10 tablet is visible again.

Network Vista and Windows 10 - peer to peer

I just set up a new laptop with Windows 10.

I am trying to incorporate it into a network with a Wirdows Vista desktop computer. (I know, time to upgrade.)

My previous Windows 10 laptop worked fine.

Now, I can see and access everything on the Vista computer from the laptop but cannot see or access the laptop from the Vista computer.

Sharing is turned on in the Windows 10 laptop.

I run a program to sync files on the desktop computer and it can't see the laptop.

 

PC is not accessible. You might not have permission to use this network resource Contact the administrator of this server to find out if you have access permissions

I am having issue with connecting to one of my computers in my home network. I have a desktop ( Windows 10 ) and 2 Laptops .One is Windows 10 and one is Windows 7.

I can access both my desktop and the Windows 7 laptop from my Windows 10 Laptop.

I can access my desktop and Windows 10 Laptop from my Windows 7 laptop

I can access the Windows 7 laptop from my desktop ... but cannot access my Windows 10 laptop from my desktop.

The msg I get is..

"\\BRIAN-PC is not accessible. You might not have permission to use this network resource.

Contact the administrator of this server to find out if you have access permissions.

Logon failure: the user has not been granted the requested logon type at this computer."

I have done all that I can think of as far as permission goes but to no avail . Help would be appreciated

LAN Problem

 

I wish I had an answer for you. I have the same problem, as of upgrade to the latest BIG update. I do not see any of the computers on the network.

I have not tried to connect to my laptop with other computers, but I can connect to it on my phone.

 

This sounds a bit like earlier issues with discovery. BTW, the error you quoted is wrong. It is 80070035. Do a search here and you will find lots of hits!

Out of curiosity, what do you get with the command prompt command net view?
And has this Laptop been upgraded to win 10 rather than clean installed?

I see you have looked at SMB versions and I think this may be the problem. When your comp uses Lanman client to interrogate a Lanman server for its shares, it uses the SMB protocol. If your client and the server use different versions they can't talk to each other so your client times out and gives the 80070035 error, path not available.

I had this problem earlier and wrote this:-
"I have done a lot of checking of services etc between my comps to no avail. But today I was drawn to the registry settings of the Lanman Server. I compared the problem comp with a good one and after a while I found a discrepancy. The Registry entry, LanmanServer\Parameters had two extra keys that the good comps didn't have. These were 'Size' and 'SMB2'. I deleted both and was amazed to find that fixed the problem (gotta remember I have had a ton of disappointments!). The shares just popped up as they were supposed to!".

Those two keys were carryovers from earlier windows versions.

Path is HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters. Check Lanman Client as well.

Can't say I can give you the fix but maybe this info will be helpful.

 

Hi, and thanks for taking the time to reply!
-Yes, it is an upgrade from w8.
-Typing net view in cmd (admin or not) returns error 50, not supported
-Yes, correct error code is 0x80070035 "Network path cant be found" (translated from Swedish)''
-I found the DWORD "Size" in LanmanServer but deleting that (and restarting) did not solve the problem. There were also other items in LanmanServer & LanmanWorkstation parameters folder that differed between the laptop(W10home,upgrade) and the tablet(W10Pro, clean install), but I did not dare to delete these without knowing what they do. Below is a list of items that differed between the laptop&tablet:

LanmanServer/Parameters:
In laptop (has problem) registry:
LmAnnounce,dword,1
Size,dword,1
SrvComment,SZ,*
*=COMPUTERNAME (name of my laptop)

In tablet(no problem) registry:
autodisconnect,dword,1

LanmanWorkstation/Parameters:
In laptop:
AllowInsecureGuestAuth,qword,1**
OtherDomains,Multi_SZ
**I added this both as Q/D word after a forum tip, made no difference

 

Googling that error 50 seems to point to network provider errors. My comp shows the ProviderOrder as RDPNP, LanmanWorkstation,webclient

Fixed.

I'm not sure how this occurred, but I thought I'd complete the thread in case anyone else finds themselves with a similar problem.

The issue was to do with the registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\NetworkProvider

I compared the broken machine against a working one and found that the broken machine had:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\NetworkProvider\HwOrder]
"ProviderOrder"="LanmanWorks,RDPNP"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\NetworkProvider\Order]
"ProviderOrder"="LanmanWorks,RDPNP"

The Microsoft Windows Network is historically known as Lan Manager (or Lanman in shorthand), but I'd never seen it contracted to LanmanWorks. True enough, on a working machine these two key looked like:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\NetworkProvider\HwOrder]
"ProviderOrder"="LanmanWorkstation,RDPNP"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\NetworkProvider\Order]
"ProviderOrder"="LanmanWorkstation,RDPNP"

After a quick modification of the those values and a reboot, all is well.

Still perturbed as to how it happened. I'm sure curious techies break machine inadvertently all the time, but I can't imagine what level of playing around caused this particular modification.

May have to seriously consider a clean install. Can you get a USB drive for backing up the laptop?

 

Thanks, I have the same ProviderOrder as you, so I guess it is correct. You are probably right in suggesting a clean install. I have a 64gb USB stick I can use to backup to my desktop or NAS. Restoring it will hopefully be faster via a working network. So annoying to have been spending so much time on this and still having to do a clean install of everything....
Thanks for your support!

 

No problems, mate.

A clean install is the way to go, now.

Let's know how you go.

 

Just to let you know, I made a clean install which solved the problem as expected. Thanks for your support!

 

Well done. There definitely comes a time for a clean install.

Cbeers.
