Windows XP SP3 I was called by a friend who had lost internet access. When going into CMD/ipconfig /all he received 'Án internal error occurred. The request is not supported. Please contact Microsoft. Added info - unable to query host name. 'When I went to his house I found the bios were up for over a minute on normal bootup. Also the 2 dvd rom drives were unobtainable (yellow blobs in device manager. I got him to get a new battery for the motherboard and that problem has disappeared, however the 2 dvd drives still disappear but are re-installed by windows on uninstalling an rebooting. The lan card is an added card as the lan on the motherboard failed a long time ago. The lan card is still working according to the Device manager although it still gives the same response to ipconfig as above. Is this something that could be cured by reinstalling windows or is it something deeper (or easier?) Any help much appreciated!
