laptop cannot connect to network

after a journey abroad, we have returned to our offices to find our laptop can no longer connect to the local network or internet.

we get the yellow exclamation mark on the nic icon in the task bar.

i have tried several things like manually entering suitable ip details in the nic properties, resetting the ip stack with netsh, removing the nic drivers and re installing them, but nothing works.

i have tested the cables and all are error free.

the laptop fails to pick up any ip details if we use dhcp client, and we are just going round in circles.

can anyone assist in helping us resolve this?

windows v7 pro 64 bit is the os being used.

many thanks

Try to disable all network adapters and allow only the one you need.

Are you supposed to use static IP address or IP address gained by DHCP?

Open a command prompt as Admin, run the following commands in list order:

 Type netsh winsock reset and press Enter.
 Type netsh int ip reset and press Enter.
 Type ipconfig /release and press Enter.
 Type ipconfig /renew and press Enter.
 Type ipconfig /flushdns and press Enter.

Restart and test.

yes i have disabled all interfaces apart from the cabled one.

we usually use dhcp but as it was not working tried static, but that does not connect either.

we do want to use our wi-fi ultimately, but we identified we cannot connect to the network even with a tested direct cable.

the strange thing is, if i connect our wi-fi wap directly to the laptop and configure the ip manually, we can access the admin portal on it using a browser.

nothing else seems to work.

many thanks

many thanks to all.

i have managed to resolve it now. i found the port on the switch was hung, and a restart of the switch fixed it.

how frustrating! spent hours messing with this.
