This post is essentially about a Windows 98 SE PC that will NOT use DHCP to pick up it's IP Address.
I'm looking at a 'friends' PC that has become unwell. I've virus scanned and removed the eight viruses it had. I'm now trying to attach the PC to the Internet to download relevent Windows updates, and this is where my problems started! The PC doesn't have a network card, so I installed one - A Realtek RTL8139. Try as I may I cannot get this thing to pick up it's IP address via DHCP.
Depending upon what else is switched on, I have Windows 98, XP and 2000 based PC's on my network. All network/DHCP/access the internet without problems. It is JUST my friends PC that for some reason will not use DHCP. Things I've done/tried:
Another port on the switch that fronts my Netgear router.
Another LAN cable
Another network card (another Realtek RTL 8139)
Added the IPAutoConfigurationEnabled key to the DhcpInfo00 section of the Registry (Set to 0)
Deleted the Dial Up adaptor/associated TCP/IP binding.
Removed the LAN card, deleted the drivers, re-installed from scratch after re-boot/power cycling.
Turned every other machine off, and tried running my friends PC stand alone
Power cycled my Netgear Router
Found a link to a file ipac_off.inf - which turns off Automatic Private IP Addressing - allegedly...
Removed ALL entries from the Registry that refer to DHCP.. Yes, it put them back!
Removed ALL entries from the Registry that refer to DHCP.. EXCEPT the IPAutoConfigurationEnabled key (set to 0) Yes, it put them ALL back!
And probably a million other things..
I'm bored now! Any help/advice appreciated.
