Trouble Shoot Network connections in XP

1) Do a TCPIP fix first
TCPIP fixes reset NIC and TCPIP

What I like to do on any network problem….Is to reset it ALL….

netsh int ip reset reset.log
netsh firewall reset
netsh winsock reset

Then remove ALL NIC’s from the device manager..
In the Device Manager, select View>Show Hidden Devices

(If the Show Hidden devices is not presetn, do the following command from a command prompt..)

start>run>cmd
set devmgr_show_nonpresent_devices=1

More information on that command here….
Device Manager does not display devices that are not connected to the Windows XP-based computer

Go back to Network Adapters, and make sure your adapters are all gone, including any older ones. (there will be several ‘ miniport’ devices that are not able to be uninstalled….)
Once they are all gone, reboot and let Windows reinstall them…

Thats a total rebuild of your network connections, to hopefully correct any problems with Basic connectivity.

2) If that does not fix it then do a

SFC /scannow from a DOS box

3) Try using a new windows User profile.

4) If that does not work, I would do a repair install
