:welcome: Try doing what I did in post # 12 above or you could just install SP3 from Windows update.
good luck
Initially the problem manifests itself as the XP machine asking for drivers when the Tether option is enabled on the connected phone. The answer to that has been documented (PDF archive) already -- use tetherxp.inf (alternate link) to tell XP how to use the driver files (that it already has) for the tether. The problem is - unless you've [COLOR=#812528 !important][COLOR=#812528 !important]installed[/COLOR][/COLOR] a device at some point whose drivers included an updated set of Remote NDIS (RNDIS) drivers, this will fail on XP SP2 and lower. It will appear to work up until the end of the driver installation whereupon the New Hardware Wizard will report "The device cannot start. (Code 10)".
The tetherxp.inf file is not the solution, the Windows hotfix is. Please carefully re-read the OP:
If followed carefully and exactly, Motocahe1's guides are flawless. If you having a problem, I'm sorry to say, it is because you are not properly follwing his instructions. I suggest you print it out and carefully follow each procedure, checking it off as you go.
good luck
I have the same problem and am looking for a solution in the end since this morning, will try to post it here tomorrow, I hope that I found useful:
??? This whole thread is the solution. Any question is answered right here in the OP.
Why all the fuss? Because when this article was written, most folks (and the author, too) were using the Motorola A855 Droid 1 and all the custom roms for it have USB Tethering built in, no need for an additional program. I've used PDA net and it is a bit more clunky than the apps you can use when rooted.
I was afraid you were going to say you don't have a wireless modem.
good luck
