When kb4088891 auto installs and updates the system it kills the network adapter from getting any internet. either by dhcp or static. but if comodo is removed and installed then put back on it works fine.
Can you please try removing CCS and install the update and push the CCS installation from the portal which should be 10.3.0.6601 . What was the version of CCS that you have on the endpoint before the update?
I am, i’ve had to reinstall the pc’s with the latest windows version and all updates before putting comodo on it.
Very odd, pretty sure we’ve not encountered this issue.
