Fix Windows 11 Access Denied

I’m stuck with a stubborn Windows 11 networking glitch inside our small office. One PC refuses to let the others in: the machine is visible, but every attempt to open a shared folder or mapped drive throws an “Access Denied” style message. This is strictly an on-premise LAN scenario—no VPN or internet-side factors involved—so the solution needs to focus on local permissions, share settings, network discovery, credential management, or any related Group Policy nuances.

Here’s what I need from you:

• Diagnose why the second computer blocks access even though sharing is enabled.
• Adjust or rebuild the relevant permissions so the share is reachable without compromising security.
• Leave me with a concise, step-by-step note of what you changed so I can replicate it on any new workstation.

You’re free to use the built-in Windows tools (Computer Management, Local Security Policy, PowerShell, etc.) or trusted third-party utilities—whatever gets the job done safely and quickly. I can provide remote access at a scheduled time and will be available for live testing while you work. Once the offending PC is accessible and the steps are documented, the job is complete.

Remote access is available using anydesk or ultraviewer
