Failed to disable RNDIS to use Serial

[pedah]

It has got to be a problem with the port or usb.

.

Had a similar problem, with axim and wm5. had to delete com ports on device to disable advanced network functionality, and set them up again afterwards.

Thanks. I will have a look now and try them out. Will post the result.

Perhaps one of our other mods or members with similar experiences might be able to help more.

It has already been a big pain for about a week now. I think I can blame the laptop, but the question is how comes that it works with other phones?
I have an SPV C500 running WM 2003 SE which connects just fine, and tried an HTC Athena with both WM5 and WM6 (even flashed it to WM6) and works fine. So still, it must be something on the laptop that is specific to this phone.
Any ideas are appreciated, I really need to sort this issue.
Thanks

How exactly do I do this?

Go start/settings/connections/bluetooth and then choose com port tab.

Then tap and hold on com ports and select delete. I don't know if your device is touch screen or not?

See this thread
and this thread that was the original clue after googling the error message.

I thought that would be it, but I have no COMs set up there. It is a fresh install, so nothing has been setup.

The only other way I've found around this is to disable advanced network functionality, FIRST after a hard reset, before I do anything else. With my
current system and programs I am
back to the same problem, possibly if you just want USB it needs to be setup before you start applying third party apps, after a hard reset.?

Now is the time to consider the image that self installs on your phone that is supplied by your provder!

I think you are right. I probably had some ports set up before flashing the ROM.
It would be interesting to see how am I oging to get out of this one
Probably even flashing the original ROM back wouldn't sort it as the COMs still wouldn't appear in the list.

Anyway, I came to the conclusion that it should work with the "enhanced network" as well as it does work fine on other computers and I tried to follow the links in boz's post
I got a tool (USB View) which shows that the USB is connected alright and the port is fine, but as soon as it is connected it is trying to set up a TCP IP connection which spends some time trying to aquire network address and then it fails. It would appear that the PC can't establish this connection to the phone. I am just going over the running services again to make sure that there wouldn't be anything else using this port.
Following this link: ActiveSync 4.x Troubleshooting Guide - Connection Flow
I can see the route being added but I can't see any connections to that destination (netstat).
If anybody has any idea of how can I debug why this connection doesn't get setup, please let me know.

I've had the same problem with my P3600- whatever I do, the RNDIS Activesync connection won't work with the current WM6 ROM, though it did with a previous one and with WM5. This is with Vista 32bit.

Luckily I was able to uncheck the USB to PC Advanced setting, allowing normal USB Activesync to work.

Have you tried running in Safe Mode then unselecting USB to PC Advanced? (try downloading a trial of Monocube SafeMode- it works really well)

I have had a similar problem using Black Satin, Vista 64 and WMDC various connection issues and errors on my laptop would sync with another laptop and a desktop even with a virtual machine running xp or vista. I narrowed it down to a sync or Outlook 2007 problem but no ammount of reinstalling or reseting would help. I eventually re installed both vista and office and for the last 2 months everything has been sweet.
