1. Check the cable if it is connected to the workstation/ notebook and if it is receiving signal from the switch.

2. Check using the command "ipconfig" to confirm the IP range that the user's machine is in if it is using APIPA address, This will mean the machine can not reach the DHCP server and if the user has an assigned static address try pinging the gateway, DNS,Proxy Server or one of the Domain Controllers.

3. If all pinged replies successfully check to see the proxy settings through Lan Settings on your Browser.

4. Depending on the structure of your corporate network you might need to check the mac address (of the user's workstation) on the cisco switches (if used) to find out which VLan is it in and move it to the correct VLan.

If you're getting an error message limited activity by right clicking on the connectivity icon on the task bar, use ipconfig /release then ipconfig /renew commands refresh the desktop and check. If the issue still persists, power off the router, switch it on after 10-20 seconds, wait for a minute and try again. It should work fine. You can check the IPV4 or IPV6 configuration as well and check proxy settings.

Check the Ip address
if it ha ARPA address release the ip address by using comman ipconfig /release and renew by using IPaddress /renew
