Computer Network Connection Failure

Network connected, but websites will not load

This can be caused by multiple issues, but the following steps can be used to troubleshoot:

• First, try restarting the computer

• Open an elevated command prompt

• Run the following commands:

  • ipconfig /all

    • If the computer has a 169.x.x.x IPv4 address, then it cannot connect to the DHCP server

  • ping 127.0.0.1

    • If this command is successful, then the TCP/IP stack is functional

  • ping <assigned IP address>

    • If this command is successful, then the network adapter is functional

  • ping <default gateway acquired from ipconfig /all>

    • If this command is successful, then the connection to the router is functional

  • ping 8.8.8.8

    • If this command is successful, then the connection to the internet is successful

  • ipconfig /release

  • ipconfig/renew

    • The previous commands will release whatever IP address is assigned and request a new one from the DHCP server

  • ping www.google.com

    • If this command is successful, then the DNS service is functional

  • ipconfig /flushdns

    • This command will remove any cached DNS configuration and request an update

The Dependency Service Or Group Failed to Start

• Run the following commands:

  • net localgroup administrators localservice /add
