Fix if you're connected to hotspot ore domain network contact the network administrator

The message indicates a general network connectivity problem on Windows, not something specific to Teams. Use these steps on the PC to troubleshoot the network connection first, then try Teams again:

1. Check Wi‑Fi or Ethernet status
   • Select the Network, Sound, or Battery icon on the right side of the taskbar.
   • Make sure Wi‑Fi is turned on (if using wireless).
   • Confirm the network shows as Connected. If not, select the correct Wi‑Fi network and connect.
   • If using Ethernet, ensure the cable is firmly plugged into both PC and router.
2. Run the Network troubleshooter
   • Select Start > Settings > Network & Internet.
   • Select Status (Windows 10) or the equivalent network page.
   • Scroll down and select Network troubleshooter.
   • Follow the on‑screen steps and apply any fixes it suggests.
3. Try another device on the same network
   • Connect a phone or another PC to the same Wi‑Fi or hotspot.
   • If other devices have internet, the issue is likely with this PC.
4. Reset network components via Command Prompt
   • Select Search on the taskbar, type command prompt.
   • Right‑click Command Prompt > Run as administrator > Yes.
   • Run these commands one by one, pressing Enter after each:
     • netsh winsock reset
     • netsh int ip reset
     • ipconfig /release
     • ipconfig /renew
     • ipconfig /flushdns
   • Restart the PC and test the connection and Teams again.
5. If still no internet: use Network reset (last resort)
   • Select Start > Settings > Network & internet.
   • On Windows 11: Advanced network settings > Network reset.
   • On Windows 10: Status > Network reset.
   • Select Reset now > Yes, let the PC restart, then reconnect to Wi‑Fi or Ethernet and sign back into Teams.
   • Note: This removes and reinstalls network adapters and resets settings; VPN and virtual switch software may need to be reinstalled.

If the PC is actually joined to a school or work domain or using a managed hotspot, the network administrator may have restricted access; in that case, contact the school or organization IT support as the message suggests.
