Cannot acquire an ip address

Hello all,

I have a major problem with my machine since I installed Comodo Firewall in order to replace Boclean. I couldn’t manage to renew my ip address while the program was installed and active, nor could I uninstall the program using add and remove programs or fwconfig. Therefore, I deleted all comodo files from both the registry and program files directory as well as uninstalling the drivers.

My problem is that I still can’t renew my IP adress (which is set to renew automatically) I’m running XP. Can someone please help me?

Thanks

Hello and Welcome =)

I see that you have ‘manually’ deleted CIS Files correct or tried the installer, and if niether did work to remove CIS Then Try This https://forums.comodo.com/install_setup_configuration_help/cleanup_tool_for_comodo_internet_security-t36499.0.html;msg259617#msg259617

Did This Help?

I’ll try to use this tool, although I believe I have already eliminated all CIS files. My problem is that I can’t renew the ip address or get online despite removal of CIS. I suppose it is possible that I missed something, so I’ll run this and see what happens

ok so I still can’t renew my ip address or get online. Any suggestions?

Follow this guide about the full removal of CIS (forget about the Legacy keys; they are too much work to remove). Make sure that there are no Comodo related drivers in Device Manager under Non Plug and Play drivers as described in the guide:

Uninstall CIS and reboot. Then run [url=http://system-cleaner.comodo.com/]Comodo System Cleaner[/url] to get rid off registry keys.

Then delete the Comodo folders under Program Files, Program Files\Common Files, C:\Documents and Settings\All Users\Application Data\ .
For Vista/Win7
Users%username%\appdata\local, Users%username%\appdata\roaming\ and \Users%username%\appdata\local\virtual store

To be even more thorough open Device Manager and set it to show hidden devices under menu option View. Then see if there are Comodo driver(s) left in non Plug and Play drivers. If so select the driver → click right → uninstall and reboot.

Now delete the following:
C:\boot.ini.comodofirewall (this file may not exist).

*Note: It may not be possible to remove these “LEGACY” keys. If you cannot delete them, leave them in the registry. However, I have subsequently found that you MAY be able to remove these keys in Safe Mode by using a third-party registry tool. To permanently remove them may also require modifying the Permissions for each key.
