Is ICS **REQUIRED** to be on for a PC connected to a router to access the internet. Or is it not required.
Situation: Windows XP SP2 PC can connect to router but has no internet. Details are below. Windows Firewall/ICS Service is off. When I Start it I get a Error 10047 saying that Windows Service will NOT start. This is singular; almost all PCs with SP2 have it on or it CAN be started if it is off. It is on for the Windows Firewall if nothing else.
BACKGROUND: XP SP2 laptop will not access internet via a wireless or wired connection to the WEP-enabled router which is connected to a DSL modem. Or to an unsecured router in another apartment. Another XP SP1 laptop right next to it will access the internet via the same WEP-enabled router or an unsecured router in another apartment. Correct WEP key (via a Linksys passphrase) has been entered on the problem laptop. Plus in any case the router in another apartment needs no correct wep key to be entered.
Router and DSL modem have been powercycled. Dos command "Sfc /scannow" did not find any system files to replace. A Windows XP SP2 Repair install completed successfully on the problem laptop. Still no internet but a Repair install does NOT replace the entire OS. A Windows install into the existing Windows partition WILL replace the entire OS but requires a lot of work afterwords (key drivers are missing, personal files are not in the right place, etc.,etc.)
When the PC is wired to the DSL modem we STILL have no internet BUT this requires some custom setup by Verizon tech support (they use PPOE plus this older Verizon DSL modem has some peculiarities that require some custom things) and if they mis-informed me on the phone this could be the problem with this situation. Nonetheless when this simple network setup failed the idea of reinstalling Windows looked like a good idea as the possibility of corrupt OS files related to networking appeared.
Please answer the question at the top of this email PLUS provide any ideas on how to get internet here short of a Windows reinstall into the Windows partition.
