2.4 Installation - Windows
Warning:
If the FAT32 file system is used, it is not possible to protect Kerio Control in the above way.
Thus, we strongly recommend to install Kerio Control only on NTFS disks.
Conflicting Applications and System Services
The Kerio Control installation program detects applications and system services that might
conflict with the Kerio Control Engine.
1. Windows Firewall’s system components 1 and Internet Connection Sharing.
These components provide the same low-level functions as Kerio Control. If they are
running concurrently with Kerio Control, the network communication would not be
functioning correctly and Kerio Control might be unstable. Both components are run by
the Windows Firewall / Internet Connection Sharing system service. 2 .
Warning:
To provide proper functionality of Kerio Control, it is necessary that the Internet
Connection Firewall / Internet Connection Sharing detection is stopped and
forbidden!
2. Universal Plug and Play Device Host and SSDP Discovery Service
The listed services support UPnP protocol (Universal Plug and Play) on Windows. However,
these services collide with the UPnP support in Kerio Control (refer to chapter 18.2).
The Kerio Control installation includes a dialog where it is possible to disable colliding system
services.
By default, the Kerio Control installation disables all the colliding services listed. Under usual
circumstances, it is not necessary to change these settings. Generally, the following rules are
applied:
• The Windows Firewall / Internet Connection Sharing (ICS) service should be disabled.
Otherwise, Kerio Control will not work correctly. The option is a certain kind of
warning which informs users that the service is running and that it should be disabled.
• To enable support for the UPnP protocol in Kerio Control (see chapter 18.2), it is
necessary to disable also services UPnP Device Host and SSDP Discovery Service.
• It is not necessary to disable the services unless you need to use the UPnP in Kerio
Control.
1 In Windows XP Service Pack 1 and older versions, the integrated firewall is called Internet Connection Firewall.
2 In the older Windows versions listed above, the service is called Internet Connection Firewall / Internet Connection
Sharing.
