Cisco VPN issues on Windows 7 Beta

[mariv]

Mariv,

I have the exact same problem with you. I can't roll back my driver as well but from google, I found the ndis.sys file is in C:\Windows\System32\drivers.

Cheers,
F4ith

Faith, I know it's stored in System32 folder but it seems like it has been modified and making confilcts. Maybe you have original file?

Rickmccl,

Your solution is ok, but did not solve my problem
Just wondering to install again my W7 7000

 

[rickmccl]

mariv I wanted to post that it does work so peeps will know. We can look at your issue if you want.

Original ndis.sys from W7.7000 is 700,680 bytes and dated 12/13/2008, 0200AM.

You might also find it in c:\windows\winsxs\x86_microsoft-windows-ndis_31bf3856ad364e35_6.1.7000.0_none_183111f35806a1f8.

WinSXS is the 'real' location of each file in c:\windows; a driver could replace the file in c:\windows\system32\drivers but it would not be able to change the one in winsxs.
Try:
cd \windows
dir /s ndis.sys

HTH,
Rick

I am sorry I am not able to access my Windows7 at this moment but I think you can restore it to the original point to get the unmodified file. I think you don't have to start from scratch again...

Rick,

Got same verison of ndis.sys with same date and size in both folders (System32/drivers & winsxs)
Additionally I've tried to install 5.0.04.xxx but again without success. Don't know what happened.

Basically I've made update from Windows 7 b. 6965 to 7000 (not fresh install) and it stopped working :|

Any ideas guys?

I'm having the same issue as well. I installed Windows 7 (build 7000) on a T60p Lenovo laptop and everything runs fine. When I install the Cisco VPN Client it works until I reboot. When I reboot I get the BSOD referencing ndis.sys. I've tried everything suggested so far in this thread to no avail.

Right now I'm going through the process of installing a few different versions of the VPN Client so we'll see if any of them work.

Vorak,

Did you run clean install of b.7000 ?

 

[dblizz98]

Yes

 

[Vorak]

Vorak,

Did you run clean install of b.7000 ?

Yup. I formatted the drive and installed it fresh.

I actually just figured out how to make it work though. Before I was just setting the installer to Vista Compatibility mode and it kept failing. This time, after installing v5.0.04.0300 and before rebooting, I set vpngui.exe to Vista Compatibility and then rebooted. It didn't blue screen and I can now use the VPN Client just fine.

If someone else can try this to verify that this is what actually worked, that'd be great!

 

[mariv]

I can try
w8 few minutes
------------------
Not working for me...

 

[Vorak]

Did you set C:\Program Files\Cisco Systems\VPN Client\vpngui.exe to Vista Combatibility mode right after you installed it?

 

[mariv]

yes, but again, reboot and BSOD welcome !

I had the same problem with my HP 6930p. Read this thread, uninstalled my wireless driver (Windows 7 had installed it perfectly) Installed the Cisco VPN client 5.0.0.4.0300 rebooted and no BSOD anymore. Windows installed my wireless driver after this reboot....everything works fine!! Thanks everybody for the tips!!

 

[mariv]

This solution doesn't work for me either...

 

[joseluis]

Same issue

I have the same issue. HP compaq nc6320 with broadcom lan driver and wireless intel/pro. I have try cisco VPN 5.0.03 and 5.0.04 and after instalation it connect correctly to work but after reboot blue screen.

 

[Mike Curry]

Same result as others

I Installed Cisco VPN .4.300 in vista compatibility mode, and it will run and connect to my office successfully, but it BSOD's upon reboot.

Running a sony vaio SZ with a Intel win 7 wireless driver.

 

[mariv]

Guys, did you observe same issue with BSOD's in build 6956?

 

[joseluis]

Issue with 7000 build...

 

[mariv]

Ok, I give up. Just reinstalled 7000 while ago, and first thing after clean install I've applied Cisco VPN client 4.300 and works perfect. Thanks to you all for hints!

 

[joseluis]

Worked for me too. Reinstall fresh copy of windows and install Cisco VPN 5.0.04.

Thank's

This worked for me.

1. Install Cisco DNEupdate. DNE Support - Deterministic Networks
2. Reboot
3. Take ownership and delete ndis.sys (in c:\windows\system32\drivers).
4. Take ownership and delete ndis.sys.mui (in c:\windows\system32\drivers\en-us).
5. Install Cisco VPN Client 5.0.04.0300 or above.
6. Reboot
7. Windows 7 will repair itself (because we deleted those files). This will take a minute or so and it will automatically reboot.
8. All should work well!
