[XPSP2] Access denied for network utilities in DOS box?


After installing Comodo FW on XPSP2 and logging on as admin, I get “Access denied” whenever I use network utiliesi in DOS box, eg. netstat, ipconfig, ping. Uninstalling Comodo and rebooting solves the problem.

Any idea what is causing this?

Thank you.


As a Network Engineer - I have to use these tools a lot for troubleshooting end devices. I, personally, don’t have any problems accessing these tools.

You could try looking under the ‘Defense+’ tab and clicking ‘View Defense+ Events’ to see if the Firewall is blocking anything in your case. Then we can go about solving this from there.



Have you defined a zone that encompasses the IP addresses in use on your LAN (including your router)? If you don’t have traffic under Windows across your LAN, you certainly won’t get traffic in a DOS session running Windows.

Thanks guys, it’s working now, after uninstalling and reinstalling it. I suspect it’s because I had to authorize svchost.exe so I could connect to that XP host through RDP from a remote Remote Desktop client, and that DOS-based network apps rely on that EXE to run.
