Sometimes when I start my computer, my LAN delays in acquiring the IP and Comodo takes a lot to initialize and when it finishes it it displayes this error (see screenshot)
If I run the Diagnostics utility I find no problem.
If I exit firewall and then open it again, the error disappears and everything is running ok.
What should I do to prevent this from happening?

No idea here ?
It happens once at 3-4 restarts.
It seems this have been fixed with the latest CIS Beta version.
I got this error again. 
Why isn’t anybody looking here ? (:AGY)
Try reinstalling Comodo. Reboot and delete all folders related to Comodo Internet Security. Then let a thorough registry cleaner clean the registry. You can try Comodo System Cleaner: http://system-cleaner.comodo.com/index.html .
I am having the same problem plus CPU usage seems to be higher (it is really higher w/ Firefox - something else I need to look at). The Application Agent not running just started in the past week or so. I am at .439 which I think is the latest, I am concerned not having firewall. What is the solution and what introduced this problem of the firewall not starting.
Also tells me to run Diagnostics which I do but tells me there are no issues.
Today mine has done the same for no reason. Unistalled, ran CSC, Reinstalled still no luck nothing in it will work FW,AV,+D.
The latest beta has version number .459: https://forums.comodo.com/beta_corner_cis-b133.0/ . Try installing it and make to sure uninstall 439 completely as I described in the above.
Nope still the service wont start. Ill put avast back on and webroot Fw and wait for the 3.8 final.
EricJH, I did as you suggested and after 3 restarts everything seems right, but… you can never know.
