Well done,sir!
You fixed BOTH problem with this release.....

version : 3.51.08
Os : Win 7 /32-bit

Forced Programs.....

SBIE2203 Failed to communicate with Sandboxie Service: RPCSS/SXS - msnmsgr.exe
SBIE2203 Failed to communicate with Sandboxie Service: RPCSS/SXS - firefox.exe

even after reinstall reboot..

Any Ideas

Yes. Can you turn on the Resource Access Monitor in Sandboxie before launching your forced Firefox?

http://www.sandboxie.com/index.php?ResourceAccessMonitor

Then post your results here. I'd like to see if I can identify any software that may contribute to causing this problem.

ok, here is the output when starting Firefox forced....

snipped. --tzuk

Andreetje unfortunately your resource log did not suggest that any other program is conflicting here. But do you use other security programs in addition to Sandboxie? Do you have some special security settings in Windows or in another program?

superkryo thanks for the problem report, I'll look into this in a few days, and post an update.

I get the same message "Failed to communicate with Sanboxie Service: RPCSS/SXS- firefox.exe
3.51.09

Windows XPsp-3
Online armor Firefox (runsafer)
Sorry forgot to metion.
Back to 3.50

Thanks whodat. Is anyone else who is seeing this error also using Online Armor with the Run Safer option?

Also in OA advance program (firefox) settings:

permissions:

set global hooks: block
Physical memory access: block
suspend process/thread: block
enumerate files: block
Direct disk access: block
system shutdown: block

protection:

Protect from suspend: checked
Protect from remote code control: checked
Protect from remote data modification: check

I don't think this has much to do about this problem?
If I run FF normal same SBIE error.

Tzuk,

I've only got MS Security Essentials installe new version V2), nothing special other software is installed.
Also with the new Beta 3.51.09 i got the same error.

Andreetje, I installed MS Security Essentials on my 32-bit Windows 7 to experiment but I didn't really expect that to cause this problem and in fact it has not caused this problem.

Are you perhaps experimenting with a service pack beta version? Or Windows SRP or some other Windows configuration that most people don't you?

Tzuk,

I'm Lost...

As far as i know i don't have any special software/configurations....
The strange thing is that msn messenger is causing also the same problem.
A forced Google Chrome is working without problems...

Regards,

André

OK, what I will do in the next beta build is add more messages to try to zero-in on the exact cause of the problem. I'm hopeful that with enough experimentation we will be able to figure this out. Thanks for sticking with beta versions to help fix this, I appreciate it.

I use Black-viper's safe configuration.
Xp-Antispy. Set as "suggested"
In Firefox 3.6.13 ; Automatically start firefox in a private browsing session.
XP-sp-3
Online Armor++

This is all that I use.

OK, this is too weird. Took off Online Armor and installed Outpost Pro then installed SBIE 3.51.09 and no messages.
But I see some people are not using OA, that have this problem.
Don't know how long this will last.
I use FirstDefense so I can mess around installing and uninstalling programs.
