Windows 10: Only One PC Can't Access Other Computers on Private Network

I have 3 PCs running on a private network using the same Microsoft account as follows: PC1--desktop Win10 Pro; PC2--laptop Win11 Home; and PC3-desktop Win 11 Pro.PC1 can access folders on both PC2 and PC3. PC2 can access folders on both PC1 and PC3. However, PC3, a new desktop, cannot access folders on the either PC1 or PC2. For example, when attempting to access PC1, the other desktop from PC3, I first get the following dialog:When I hit OK, I get this error message.I get the same set of messages when trying to access the laptop.Please advise. Thanks.

Credentials Needed to Access Computer over Private Network

Hello there,

I understand you're facing challenges accessing shared files and folders between your Windows 11 Pro and Windows 10 Pro computers on a private network. Sharing resources on a network can involve a bit of configuration, so let's work through some steps to help you out:

1. Create Matching Local User Accounts:
   
   • On both PCs, set up local user accounts with identical usernames and passwords.
     
   • Use these credentials when prompted while accessing shared resources.
     
2. Adjust Network Discovery and Sharing Settings:
   
   • Open the Settings app on both computers.
     
   • Navigate to "Network & Internet" > "Sharing" (Windows 11) or "Network & Sharing Center" > "Change advanced sharing settings" (Windows 10).
     
   • Make sure that network discovery and file and printer sharing are enabled.
     
3. Use "Connect using different credentials":
   
   • When asked for credentials, try "Connect using different credentials."
     
   • Format the username as COMPUTERNAME\USERNAME (e.g., PC1\John).
     
   • Enter the corresponding password.
     
4. Shared Folder Permissions:
   
   • On the Windows 10 computer, right-click the shared folder and choose "Properties."
     
   • Head to the "Sharing" tab, then click "Advanced Sharing."
     
   • Confirm that "Permissions" for Everyone or the specific user are set to "Full Control."
     
5. Windows Credentials:
   
   • Access Control Panel on the Windows 10 computer.
     
   • Go to "User Accounts" > "Credential Manager."
     
   • Under "Windows Credentials," add a new credential with the network path of the Windows 11 computer and the local account's username and password.
     
6. Windows 10 Local Group Policy:
   
   • Type "gpedit.msc" in the Run dialog on the Windows 10 computer.
     
   • Navigate to "Computer Configuration" > "Administrative Templates" > "System" > "Credentials Delegation."
     
   • Enable "Allow delegating saved credentials with NTLM-only server authentication."
     
   • Add "TERMSRV/*" to the policy.
     
7. Windows Defender Firewall:
   
   • Confirm that Windows Defender Firewall isn't blocking network sharing.
     
   • Double-check your network profile (Private/Public) and ensure sharing is allowed based on your profile settings.
     
8. Network Troubleshooter:
   
   • Run the Windows network troubleshooter on both computers to diagnose and address network-related issues.
     

Remember, maintain strong passwords for user accounts and follow good security practices. I hope this helps you resolve the sharing problem effectively.

PC Networking/Sharing on Private Network

We have latest Windows 10 on 3 PC's in our home. They are all connected to the same wifi secure connection. I've configured all 3 for sharing over a private network but have not been able to access the other PC's. I can see one of the computers but
it is saying that I don't have permissions to access, to contact my administrator (that's actually me and I'm listed as administrator). This networking worked well with homegroup in earlier versions but since Windows 10 update I have no longer been able to
network and open files on other PC's. I would think this would be much easier in Windows 10. Does anyone have any suggestions to make this work? Thanks in advance.

 

One computer cannot access other network computers.


So I've tried every troubleshooting step I know:

• Double checked that Net Bios was enabled
• Ran a bunch of network commands:
  • flushed DNS
  • registered dns
  • pinged and located the named computers successfully
• Reset my router to factory settings

Nothing works when I try to access via explorer. I'm still baffled by the fact that every other computer can access each other AND access this computer. It's just the outgoing connection from this machine that doesn't work.

Any thoughts?
