What happened to Windows online capability when I installed Ubuntu, and how can I get Windows to work online again?

All you have to do for if the machine can't grab an i.p. is... 1. search for the file 'tcpip.sys' - results will show 5 or so files named 'tcpip' - 2 of the results(both will be named 'tcpip.sys') will be from a recent modified date while the other 3(named 'tcpip.sys.original') will be from a much earlier date 2. delete the two recent 'tcpip.sys' files 3. rename the 'tcpip.sys.original' files to 'tcpip.sys' 4. uninstall the NIC Ethernet adapter - Start > right click My Computer > properties > click Hardware tab > Device Manager > Network Adapters > right click NIC Ethernet Adapter and uninstall 5. reboot - when Windows restarts, it'll detect NIC Adapter as 'New Hardware found' and will install 6. go online!!! Narfle the Garthok Posted at 7:22 pm on Aug. 26, 2008 Did you put Ubuntu on a separate partition or were you using a Live CD? If you installed Ubuntu on the same partition as your Windows I see you may be running into some problems. rand0mguy Posted at 6:29 am on Aug. 24, 2008 y do u think ubunutu comes with  live cd function so u can try it without affecting ur settings scalywag66 Posted at 1:56 am on Aug. 24, 2008 Quote: from the general lee at 1:30 am on Aug. 24, 2008 did you try to reinstall windows Negative.  I dont have the System Recovery Discs, which includes the installation of Windows if you fdo a full restore. the general lee Posted at 1:30 am on Aug. 24, 2008 did you try to reinstall windows All 5 previous replies displayed.
