How to Fix 0x80070035 Error – Windows cannot access UNC path (error code 0x80070035)

Windows cannot access UNC paths (error code 0x80070035) is an error that affects users who are trying to access shared resources on a Windows Server 2008 R2 host. This issue can be frustrating for IT administrators and users alike, as it prevents them from accessing critical files and resources.

This error occurs when the Windows 8.1 PC cannot find the UNC path on the server, despite being able to connect via IP address. Other computers with similar configurations should be able to access the UNC path without issues.

💡 Why You Are Getting This Error

• The primary reason for this error is that the Server 2008 R2 host may have a misconfigured or missing NetBIOS name resolution. When the Windows 8.1 PC tries to access the UNC path, it relies on NetBIOS to resolve the server's hostname to an IP address. If this process fails, the error occurs.
• Another possible reason is that the Server 2008 R2 host has a firewall or antivirus software configured to block incoming connections from the Windows 8.1 PC. This can prevent the UNC path from being accessed even though the PC can connect via IP.

🔧 Proven Troubleshooting Steps

✨ Wrapping Up

To resolve the 'Windows cannot access UNC path' error, first check the Server 2008 R2 host's NetBIOS name resolution settings and configure the firewall and antivirus software accordingly. If the issue persists, test the UNC path connection again on the Windows 8.1 PC to ensure that the problem is resolved.
