Hello Ivan,
Since you can see the computers but not access them, discovery is fine — the issue is with sharing, credentials, or firewall on the target PC. Please try the following on the computer you’re trying to access:
Step 1 – Check Network Profile
- Settings → Network & internet → Properties
- Set Network profile = Private (check on all PCs).
Step 2 – Enable Sharing
- Settings → Network & internet → Advanced sharing settings
- Under Private networks: Turn on Network discovery + File and printer sharing.
Step 3 – Reset Stored Credentials
- Run:
rundll32.exe keymgr.dll,KRShowKeyMgr - Delete saved credentials.
- Restart Windows Explorer.
Step 4 – Verify Firewall
- Windows Security → Firewall & network protection → Allow an app through firewall
- Ensure File and Printer Sharing is checked for Private networks.
- If domain-joined, check it for Domain networks as well.
Step 5 – Test Access
- Try:
\\COMPUTERNAME\sharename - If fails, try:
\\192.168.1.100\sharename
Optional Quick Fixes:
-
net use * /delete /y -
ipconfig /flushdns
After doing these steps, try the connection again. If it works via IP but not name, it’s DNS/NetBIOS. If it still fails, it’s either permissions or firewall blocking.
