Unable to access Windows 2003 shared folder from Windows 10

---

We have some folders shared on old windows 2003 box, while trying to access them from windows 10 workstation, we are seeing following error …

 

In Windows 10 Fall Creators Update and Windows Server, version 1709 (RS3) and later versions, the Server Message Block version 1 (SMBv1) network protocol is no longer installed by default. To enable it ,

Start powershell with privilege mode (on your windows 10 workstation) by >

Open CMD in privilege mode, and start powershell 

powershell

Now get status of ​SMB1Protocol

Get-WindowsOptionalFeature –Online –FeatureName SMB1Protocol

Probably it will be in Disabled State, change it to enable using following cmd,

Enable-WindowsOptionalFeature -Online -FeatureName SMB1Protocol

Afterwards, it may ask you to reboot machine, Do it to restart so that changes can take effect.

Disable SMB v1 in Windows

Open powershell cmd, and issue

Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters" SMB1 -Type DWORD -Value 0 –Force

Disable SMB1 using Windows registry

You can also tweak the Windows Registry to disable SMB1.

Run regedit and navigate to the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters

In the right side, the DWORD SMB1 should not be present or should have a value of 0.

The values for enabling and disabling it are as follows:

0 = Disabled
1 = Enabled
