I tried PE evaluation and after it expired I uninstalled it. It asked me to restart computer to finish the uninstall process. I did that and after reboot, my network was disabled. I can not ping my router, I can not do "ipconfig /renew" - it tells me some operation attempt on something which is not a socket. Then I re-installed port explorer - everything is fine again, although PE is still expired! Did the uninstall process removed something which should not be removed? What happened? I have Windows 2000 Professional. All the patches have been installed.
