-- Posted by scalywag66 at 1:17 am on Aug. 24, 2008 Well, I downloaded and installed Ubuntu OS on my machine, just to try it out.  It seems like a cool and easy operating to navigate through, and so far I like what I see and am able to do it with it.   Problem is, while Ubuntu is able to go online, Windows is incapable of it now.  Going into the CMD prompt and doing IPCONFIG brings up "Unable to Query Host Name".   My friend and I had this problem and I was able to fix it by uninstalling the Ethernet NIC adapter and letting Windows reinstall upon reboot.  This time however, that solution seems to be a futile attempt, and right now I'm on Ubuntu trying to sort this out. What happened to Windows online capability when I installed Ubuntu, and how can I get Windows to work online again? -- Posted by the general lee at 1:30 am on Aug. 24, 2008 did you try to reinstall windows -- Posted by scalywag66 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. -- Posted by rand0mguy 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 -- Posted by Narfle the Garthok 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. -- Posted by scalywag66 at 5:21 pm on Aug. 30, 2008 Solution remembered and am back online on Windows!!! What a newb I am. I can't believe I forgot about the other step to fixing the issue. 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!!!
