5. C-mount Cameras
   These cameras are similar to box cameras but with the ability to change lenses. Ideal for various surveillance applications where lens flexibility is required.

6. Wireless Cameras
   Wireless CCTV cameras connect via Wi-Fi or cellular networks, offering easy installation without the need for extensive wiring.

7. Hidden/Covert Cameras
   These cameras are discreetly embedded in everyday objects like smoke detectors or clocks, ideal for covert surveillance.

Fix: Can't Access Shared Folder in Windows XP, 10 and 11

Why Can't I Access a Shared Folder on Windows ?

If you’re getting an "Access Denied" error when trying to open a shared folder on Windows XP, 10 or 11. It’s likely due to permission issues, firewall settings, or network configurations.

Common Causes & Solutions

1. Check and Disable Windows Firewall Service

Windows XP’s built-in firewall may be blocking network sharing. Disable it completely:

1. Click Start → Run, type services.msc, and press Enter.
2. Find Windows Firewall/Internet Connection Sharing (ICS).
3. Right-click and select Stop.
4. Right-click again → Properties → Set Startup Type to Disabled.

2. Disable Simple File Sharing

Windows XP uses Simple File Sharing, which can restrict access. Disable it to manage permissions manually:

1. Open Windows Explorer (Press Win + E).
2. Click Tools → Folder Options.
3. Go to the View tab.
4. Uncheck "Use simple file sharing (Recommended)".
5. Click Apply → OK.

3. Set Proper Folder Permissions

1. Right-click the shared folder → Select Properties.
2. Go to the Security tab.
3. Click Add → Type Everyone → Click OK.
4. Under Permissions, check Full Control, Modify, and Read & Execute.
5. Click Apply → OK.

4. Enable Guest Account (If Needed)

1. Click Start → Run, type lusrmgr.msc, and press Enter.
2. Click Users → Double-click Guest.
3. Uncheck "Account is disabled".
4. Click Apply → OK.

5. Check Network Sharing Settings

1. Go to Control Panel → Network Connections.
2. Right-click your Active Network Connection → Select Properties.
3. Ensure "File and Printer Sharing for Microsoft Networks" is checked.

6. Reset Network Connections & Flush DNS

Sometimes, network issues can be resolved by resetting settings:

netsh int ip reset
netsh winsock reset
ipconfig /flushdns
    

Restart your computer after running these commands.

Additional Troubleshooting

"Network Path Not Found" Error?

Ensure both PCs are in the same workgroup:

1. Go to Control Panel → System → Computer Name.
2. Click Change → Ensure both PCs have the same Workgroup Name.
3. Restart both computers.

Access the Shared Folder Using an IP Address

If the issue persists, try accessing via IP address instead of the computer name:

1. Press Win + R to open Run.
2. Type \\192.168.X.X (replace with the actual PC's IP).
3. Press Enter.

Conclusion

If you can’t access a shared folder in Windows XP, the issue is usually caused by firewall settings, incorrect permissions, disabled guest access, or network misconfigurations.

Tip: If you’re still using Windows XP, consider upgrading for better security and compatibility! 🚀
