Crashes under Windows 2003 SP1

Hi all,

I have tested LnS 2.05p2 (base install) under w2003-SP1 and here are some results:
- do not seem to crash with base 2.05sp2 version, standard settings (no advanced option such as DLL, stateful TCP, etc.)
- seem to crash when using an advanced option (DLL, stateful TCP, etc.)

With the supplementary patches for lnsfn(1).sys:
- crashes (bsod) are VERY frequent with these latest patches. Cannot almost use the computer.

Hints:
- I am using also CfosSpeed; seem like the interaction between these 2 programs is unstable? (After having installed CfosSpeed, I had to reinstall everything from the start because LnS was crashing at every reboot. Then reinstalled everything from scratch carefully. Worked fine until I activated the advanced options. I reverted back to standard options but am still anxious about server crashes).

Crash info:
- Lnsfn1.sys : base BAE8469B at BAE77000 datestamp 413E0419

Have you got some tips for W2K3 so that I can use it under this system without fear.

Thanks,
Kran.

 

Hi,

Probably the features causing this issue are:
- watch thread injection
- watch DNS Calls
- the new ones from the new lnsfw1 beta driver activated with the registry

Perhaps you have a processor with the Nx bit/DEP protection ?
In that case you will find some related topics:

Otherwise, could you send us (lnssupport@soft4ever.com) a minidump file (these files are created in c:\windows\mnidump) and join us also the lnsfw1.sys file you were using when you got the BSOD.

Thanks,

Frederic

 

I use windows 2003 server too。
My experience is if you open the follow features,the BSOD is occure.
- watch DNS Calls
- DLLs detect.

Only one of this is opened,the BSOD must occure.

 

I'm experiencing the same problems with win2k3 sp1 and cause of this , i have to use outpost firewall .

After reading some threads , i'm gonna try again but this time i will disable "thread injection" and the DNS thing.

 

You need to disable DEP in Windows 2003 SP1 if you want
your machine to run applications like it used to. Otherwise,
you will find many apps crash, especially those written by
kick*ss programmers.

Disable DEP in Windows 2003 SP1 and beyond by editing
the boot.ini file as follows:

Code:

C:\>notepad boot.ini

Change the /NoExecute line to:

Code:

/NoExecute=AlwaysOff

Your machine will now act more like it used to.

If you have no such line then you have not installed a
DEP-capable version of Windows or I suppose your processor
does not support DEP.

I have not tried LnS, but I have lost two Win2k3 installs
due to Kerio 2.1.5, so now I am trying to be very certain
my next firewall supports Win2k3.
