VPN access and Blue Screen of Death

Go to solution

I work from home a lot, and use a Lenovo Thinkpad W510 running Windows XP Professional. To access the company Intranet, I find Wifi using ThinkVantage Access Connections, and then access the intranet using the AT&T Network Client.

 

Unfortunately, since Infinity was installed, every time I try and send an email using Lotus Notes with a decent-sized attachment (e.g. 2MB), I get a "Blue Screen of Death" in "agnfilt.sys".

 

I don't get any error using Access Connections and the AT&T client over 3G.

 

I'm totally lost as to how to proceed! Any advice would be appreciated. Many thanks in advance.

 

Cheers,

 

- Pete

Thanks DS. I found similar advice on the web yesterday, and I have this disabled. Unfortunately, the problems continue ... 😞

Hmm, had a quick look on the WWW and it appears to be related to AT&T Global Network Firewall software - If this helps?

 

Maybe checking the firewall settings may solve this....

Thanks again DS - although this firewall is disabled (Symantec providing the firewall of choice). I hope to get with our IT guys soon to see if they have any ideas!

 

Cheers,

Wouldnt it be easier to just skip the client and pop a VPN router on the line, something that works with infinity, adsl etc?

 

Something like this DrayTek Vigor 2830n Wireless-N VPN Router ?

Visited a company IT department today and an engineer looked at the AT&T Net Client settings. It now works - this may have been the "fix" for those in a similar predicament (all in the AT&T Net Client):

 

1. Click "Settings".
2. Click "Show the login properties window".
3. Click "Configure".
4. Click "Next".
5. Select the "Both the internet and my company's intranet" radio button.
6. Select "Managed VPN - SSL DualAccess" from the dropdown.
7. Click "Finish".

 

Cheers,
