Lost access to samba from windows 10 VM

[kolofotias]

I lost samba access after a VM switch to another VM.

 

I shut down windows 10 vm, booted up a MacOS VM and shut it down after 10 minutes. Rebooted windows 10 VM and lost access to all samba shares (both private and globally shared)

 

Restarted array - rebooted server - still no access...

 

Connectivity is fine - ip is acquired - internet access - unraid webui access uninterrupted. Writing this post from my VM right now.

 

No special samba config - latest version of unraid - had problems with with samba in 6.10 that was temporarily fixed with 6.10.2

 

My win 10 laptop and ipad have samba access with no problems in r/w.

 

Diagnostics attached. If anyone has any idea what's going on.

What error message is Windows giving?

 

How are you attempting access?    WIndows Explorer?  Mapped Drive?

 

Is the server--- Tower ---showing up under 'Network' in Windows Explorer?   If it does, what happens if you click on it?  

 

What happens if you use this address       \\192.168.1.200     in the address bar of Windows Explorer? 

 

Is your server set up to be the Local Master?   Settings   >>>   SMB   >  Workgroup Settings

 

 

[kolofotias]

Windows

error occurred while connecting to X: network drive as in screenshot

 

Mapped drives with IPs, +1 symlink folder

 

Tower is showing up in network discovery - not able to access it though

 

Nothing with \\192.168.1.200 on address bar

 

Yes it's set as LM as in screenshot 

 

Routing table seems a little weird to me but never checked it before

 

Everything runs under opewnrt dhcp service that works fine for local clients.

 

Tried to delete credentials and rebooted - No access - it won't even ask for my login credentials when trying to access. SMBv1 disabled - enabled no difference.

 

ipconfig with either virtio or vmxnet3

Firewall off

enabled netbios in ipv4 settings

 

No luck

 

error code is 0x80070035

 

Tried to remap drive - no access to \\192.168.1.200\*

 

 

[Frank1940]

Open a Command prompt window (on the Windows10 computer and type:

net use * /delete

 

Also check to see that you have reserved the IP address (\\192.168.1.200) for your server on your router.  

 

Also try to access  \\TOWER  in Windows Explorer. 

 

BTW, MS has turned off client access to servers as a 'guest' client.  This means that you must have a valid SMB user login on a server to gain access even to 'public' shares on a server! 

[kolofotias]

Strange

 

net use * /delete gives me:

 

C:\WINDOWS\system32>net use * /delete
There are no entries in the list.

 

Cannot right click the netdrives to delete them

 

\\TOWER  gives me same error 0x80070035

 

Complete meltdown of samba access and it's something to do with the VM.

 

Will fire up macOS vm to see if I can get access from there.

 

[kolofotias]

MacOS vm has normal access with guest and user account in my shares.

 

Windows rebooted but still no luck.

 

will run dism and chdisk now...

[kolofotias]

chkdsk and dism with no issues....

Deleted entries in regedit for my netdrives also. Still there...with red X. cannot remove them.

 

Just got destroyed by a simple reboot....

 

Will probably have to make a new vm with same disk hoping that i won't lose my setups and try again.

 

If it's windows I will format and do a fresh install. If it's unraid network setup it may be resolved.

 

What else should i check before?

Did you try rebooting the entire server?

3 times....

[kolofotias]

sfc no errors

all services restored to default

nothing

[kolofotias]

Changed MAC address a few times. Updated drivers. Restored the windows system

 

Still nothing. Others PCs have access with the same account.
