Have tried to see if this is already in Forum somewhere but failed..........
Have just set up a Wireless/Wired network into NTL (with thanks for help rec'd here in making the buying choice). So far have not done any of the wireless connections, just the wired ones, so have turned wireless off.
Two desktops on XP Pro wired up and working perfectly as far as Internet connection sharing.

HURRAH!!
Have not tried to file/printer share yet as at this point in time being a network novice I don't know how to set this up and no time to read up (even if I have the info I need!!)
More immediate problem tho is with an older third PC. I have wired this, adding a PCI Ethernet card as it had no connection. It's on Win 98SE which I cannot change due need to run some older software, and it was formerly only set up for dial up connection.
The E/Net card install seems OK, driver loaded OK and the device is registered and reports working properly in Device Manager.
Command line "pinging" the router from this PC gives replies back from the router in similar form to the two working PC's, e.g. I think it's connecting with the router OK. Router has a green light for this connection once the PC is booted, as with others.
However, Windows keeps reporting RPCSS "Illegal Operation" errors in module "unknown" (didn't before!), and progs like IE, Anti Virus updater, etc cannot find the Internet.
In case RPCSS had corrupted, I have extracted it from the Windows CD Cab's and reloaded it...no different................
Head, in over my.....rearrange please.......................... Help!!
