Issues mapping a shared drive on a Windows XP machine from a Windows 10 machine

Question

I am having an issue mapping a shared drive on a Windows XP machine from a Windows 10 machine. I can ping the Windows XP machine from the Windows 10 machine and vice versa. However when I try to map the shared drive I get the following error "The specified network password is not correct"
I am specifying the share drive as \XP_Machine_IPAddress\sharedrive. For login credentials I put in the userid (no domain as it is on a workgroup) and password for the XP machine.
The Windows 10 machine is on a domain, and the Windows XP is on a workgroup
I have enabled SMB1.0/CIFS File sharing support on my Windows 10 machine, and the IP addresses on both the Win 10 and XP machines are assigned using a DHCP server. I have turned on network discovery and file and printer sharing on my Windows 10 machine.

Previously, I had not had this issue mapping the drive from a standalone Windows 7 machine, so I installed a Windows 7 Virtual machine using Hyper-V on my Windows 10 machine, but the issue is still happening. There does not appear to be an issue mapping a drive on either the Windows 7 or Windows 10 machines from the Windows XP machine.
Thanks.

Hi @Arun Srinivasa ,

Thank you very much for your feedback.

I would suggest you try the following methods to see if the issue can be resolved.

Method One.

Please run the following command in PowerShell to double confirm if the SMB 1.0 was enabled on Win 10.
Get-WindowsOptionalFeature –Online –FeatureName SMB1Protocol

Method Two.

If the SMB 1.0 was enabled, please try the following steps on Win 10.

Open Local Group Policy Editor-->Security Settings-->Local Policies-->Security Options--> find Network Security: LAN Manager authentication level, right click it and select Properties-->select Send LM&NTLM - use NTLMv2 session security if negotiated--> click Apply and OK

Method Three.

If the issue still existed by applying above setting, please try to select Sent LM & NTLM responses in properties of Network Security: Lan Manager authentication level.

Best Regards,
Sunny

Hi,

Thanks for posting in Q&A platform.

I have done a test in my lab. And here is the result for your reference. (Please understand that we do not have such Windows XP device for testing, so I prepared windows clients with later OS)

A workgroup Windows client
A domain joined Windows client

They can ping each other successfully.

I created a shared folder on the Workgroup Windows device and shared the folder to everyone. And I tried to access the shared folder from domain joined device successfully with entering the administrator account of Workgroup device. And then I can created map drive of the shared folder on domain joined machine successfully.

So before we go further, I would like confirm the following information:

1. Besides you cannot create a map drive on Windows 10 client, may I know if you could access the shared folder on XP device directly? If you couldn't access the shared folder directly, what's the error message?

For login credentials I put in the userid (no domain as it is on a workgroup) and password for the XP machine.

2. I would like to know if the userid and password for the XP machine is the administrator account of XP machine?

Best Regards,
Sunny

Hi Sunny,

Thanks for your reply.

My answers to your questions are below:

1. I tried to directly access the shared folder on XP device from the Windows 10 machine by typing the following in explorer:
   "\XP_Device_IPAddress\ShareFolderName"
   ` It then prompts me for the network credentials, once I enter the credentials for the XP machine, it
   gives me the error "The specified network password is not correct". I repeated this by trying to access the C drive on the XP machine which is also shared as C$ by typing
   in "\XP_Device_IPAddress\C$", but I get the same error message. I also tried to enter only the IP address "\XP_Device_IPAddress" , but in this case the error message is
   "The user name or password is incorrect"
2. The XP userid and password that I am using belong to a user account that is listed as
   "Computer Administrator".

Please let me know if I can provide you any other information.

Regards,

Arun

Hi Sunny,

Thanks for your reply above.

Using both methods 2 and 3, I am now able to map a shared drive on my XP machine from my Windows 10 machine. This has been a very helpful solution to my problem.

I did notice a couple of things that I want to clarify:

1) Sometimes when I restart both the machines, and then click on the mapped XP drive letter from explorer in my Windows 10 machine, I just get the spinning circle and it does not go away until I restart the XP machine, disconnect the mapped XP drive from the Windows 10 machine, and then reconnect the mapped drive once the XP machine restarts. Is there any thing that could be done to address this issue.

2) Also all my tests so far have been with the firewall on the XP machine turned off. Once I turn on the XP firewall and add a bunch of exceptions including allowing "File and Printer sharing", I cannot map the drive any more from the Windows 10 machine. Is there a way to map the drive with the XP firewall turned on. The firewall is turned on, on the Windows 10 machine.

Also I want to make sure under "SMB 1.0/CIFS File sharing support" that I have to check all the 3 boxes:
SMB1.0/CIFS Automatic Removal
SMB1.0/CIFS Client
SMB1.0/CIFS Server

I appreciate your assistance so far.

Regards,

Arun

Answer 5

I cannot answer your questions but can tell you that none of the suggested network changes should be needed and the Windows Firewall can be enabled with its default settings on both machines.

I regularly do as you require, mapping a Win 10 PC to a Win XP PC (or the reverse) without any problems. As a test I just attempted the same with a Win XP VM running on another Win 10 PC. The outcome was the same.

There are two possible differences from your setup. All machines are running with the same user account and the Win XP machines only do not have a user password set. The network is WiFi using a standard ISP router with DHCP turned on. As far as I remember, in the past (in my office) I was able to achieve the same outcome with one machine only connected to a domain server.
