Only way I can get workstation and netlogon services to start is to boot with disable driver signature enforcement option.   How can I track down what driver is effecting this issue?

Is the machine certified for Windows 7?  It would seem like a network driver. Windows 7 is very good with wired drivers and any good manufacturer will have the correct wireless drivers.

Another place to look for some manufacturer types is Video drivers.

Find the support site for your machine, get upgraded or same wired, wireless and video drivers. Uninstall the current and install the newly downloaded drivers.

See if that helps.

If no, please post the make and model of the machine.

Windows online search reports best driver already installed

Intel 82567V-2 Gigabit NIC

Ran Driver Magician and updated recommendations.  Maybe not good?

The Intel page for that card show driver levels up around V17 or V18. Why are you using V10?


http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Ethernet+Components&ProductLine=Ethernet+Controllers&ProductProduct=Intel%c2%ae+82567+Gigabit+Ethernet+Controller

The version for my (now aging) Thinkpad with an Intel 82566 is V9.

You might have the correct version, but look through the link above for a different NIC driver.

I do not use Driver Magician at all. I find manufacturer's drivers generally better.

Also try this site for Video. You don't say Windows 32-bit or 64-bit so there was no way to go farther.

Finally look for Chipset drivers for your board and see if you can update Chipset.

From intel.com I ran their driver scan utility.  Only said I needed an audio and chip set update however the chip set driver fails.

The chipset driver should not fail. That suggests the board is not certified to run Windows 7.

I did check through the documentation for my own chipset driver (Intel) and uninstallation is not supported.

So if you cannot install the same or newer chipset, I am not sure what you can do. But probably this is at the source of your overall issue. The only thing I can suggest is to see if there is an earlier version you can download.

Is this a new installation of Windows 7?  If not, what were you running before Windows 7? If yes, then is the board new and returnable?

Another possibility is that driver attempts have possibly corrupted Windows. If you have a spare hard drive, you could try installing Windows fresh and see if the same error crops up.

Also, I have no problem connecting to Internet and browsing.  I can also ping all addresses within our company network.  I can also RDP from outside to this machine.  Network hosts resolve.  DHCP works.   I just cannot map network drives.

Network hosts resolve.  DHCP works.   I just cannot map network drives.

That normally points to a firewall or TC{/IP stack problem. But when the error occurs on any of my or my client machines, the solution is never signature enforcement.

What about my questions:

Is this a new installation of Windows 7?  
If not, what were you running before Windows 7?
If yes, then is the board new and returnable?

Plan today is - uninstall NIC driver and video driver then let Windows PNP install recommended.  Double-check BIOS update.  Try to install chip set drivers in Safe Mode.   Will report back with status.

Overall that is a good plan. If you need a BIOS update, it mighty possibly help wth the chipset update. I think we need to get the chipset driver installed.

Another thought would be to get a USB NIC, disable the on-board NIC, install the USB NIC and see if that changes anything.

Just in case -- how do we install Windows 7 over the top of existing?  Old days we either just re-applied the service pack and that would fix a lot of stuff like this.  Older OS's we could just reinstall over existing, apply service packs, redo all the updates and everything was back to normal.  This machine has very limited restore point as in only one from recent but not old enough to make any difference.   sfc /scannow or Windows Repair has not yielded anything helpful either.

With a Windows 7 DVD you can do a repair install. I have attached a link here that provides a short tutorial on this process.
