WMDC not working on Win7

jbass350z · #1 (**permalink**) 11-26-2009, 01:06 PM

OK. I have a strange problem. I built a new PC and loaded Win7 x64 on it. Everything was working fine. I was even using my TP2 to tether. This worked for about an hour. After a few reboots and software installs, I could no longer connect to my TP2 either through tethering or through WMDC.

I struggled for hours to figure out the problem, but nothing worked. Finally I reinstalled Win7 hoping that would fix it. Nope. It did not. No matter what I try, Win7 fails to install the driver for the device. I have downloaded new copies of WMDC from MS and that hasnt helped.

Any thoughts? It is working fine on my Vista machine.

Not to sound like a jerk, but I've got a machine that I upgraded to Win 7 and it works for me.
I have, however, found that it's nearly impossible to synch my TP2 with 2 computers. It works the first time, but then stops.
Do you synch to another computer ? It seems that the first machine you synch to becomes the primary computer and the next machine becomes secondary . Synching with the primary machine works like a charm, but synching the secondary computer becomes very unreliable, no matter how many tricks you try.

If you haven't done so, you might try going into the device manager and removing the TP2. Uninstall WMDC as well. Then, when you connect up your phone, WMDC should install automatically. Other then that, I'm out.

Good luck, I hope that may have been helpful.

The weird thing is it was working fine for a few hours. After a reboot it stopped working, and nothing i have done has gotten it to work. I keep getting this driver failing to install:

Remote NDIS based internet sharing device ---> X FAILED

I have tried this many times. When it tries to install the driver, I always get "Remote NDIS based Internet Sharing Device ---> X Failed.

I have hard reset the phone. Reinstalled Win7. Uninstalled/reinstalled all drivers/WMDC.

Try removing WMDC, then open Device Manager and find the network device.
Remove it from there, and make sure it uninstalls the driver.
Then reboot.

After rebooting, connect the phone - now it should detect it, and download WMDC to get the driver.
Thats what it did for me back in the RC build, so maybe it fixes it for you too.

remove form under "Portable Devices"

or try this

Steps

1. Click Start, click Control Panel, click System and Maintenance, click Administrative Tools, and then double-click System Configuration.
2. Click Continue, or provide Administrator credentials if prompted.
3. Click the General tab, and click Selective startup.
4. Under Selective startup uncheck Load startup items.
5. Click the Services tab, check the Hide all Microsoft services box, and then click Disable all.
6. Click the Apply, then OK, and then Restart

I am having a similar problem. I was running the Stock TP2 Verizon rom, until I upgraded to MightyRom 11/25 - no problem syncing on my first Window 7 64 bit machine with Office 2007, but no dice syncing with my second PC running Windows 7 64 bit, but with with office 2010 beta (no problem before upgrade to mightyrom).

It would be really nice if I could move my personal domain, with 4 email accounts, to exchange 2007 / 2010 somewhere on the internet. If someone is feeling generous, feel free to PM me.

And I hope the Dallas Cowboys go down in flames.

OK. Is it actually trying to connect to the internet to get the driver? That could be a problem since I dont have internet. I am having to use my phone for tethering for a few weeks. I have downloaded WMDC several times and installed it.

I tried everything saj070 listed and it still does not work. Does anyone have a RNDIS driver I could manually install?

Well, after almost 24 hrs of looking I found what my problem was. I have an intel P55 motherboard. In the BIOS, C-State has to be enabled (not set to auto). I have no idea WHY. I just stumbled across someone with the exact same problem and that was their fix.

This makes no sense whatsoever since the C-state is a power saving feature from what i understand.

Were you able to sync contacts on your machine running 2010? Ever since I switched to 2010 all the options to sync contacts and calendars is grayed out or unelectable. I am hoping they will post a newer WMDC before the official release date for 2010.
