Do you run ESET on Windows Server 2003/2008/2008 R2?

What will happen?

ESET Windows Server product version 7 may stop working properly on Windows 2003, Windows 2008 and Windows 2008 R2 without SHA-2 support.

Scenario 1
Product is updating from official ESET update servers

Your ESET product version will continue updating most of its modules, including the detection engine, on operating systems without SHA-2 support. However, we will be unable to fix for you or improve some functionality (such as Anti-stealth, HIPS, Firewall). Ultimately, your ESET product will be unable to provide sufficient and up-to-date protection.

Your ESET product might also be reaching End of Life during the year 2021.

Scenario 2
Updating from an update mirror

No later than the end of March 2021, your ESET product will no longer be able to load all its modules after an update on operating systems without SHA-2 support. Some modules, such as Anti-stealth, HIPS, Firewall, will stop working, and the protection status of your ESET product will turn Red. Ultimately, your ESET product will not be fully functional and will be unable to provide sufficient protection.

What can I do?

Microsoft Windows Server 2003 or 2003 R2 SP2 does not support SHA-2 at all. Install (downgrade) the latest build of ESET Windows Server product version 6.5 if you run Windows Server 2003.

To continue receiving protection and the latest ESET features, users running the versions of the Windows Server operating system mentioned below must apply the appropriate operating system version patches, but not all operating systems support SHA-2.

Download and apply the patches according to your operating system version:

Microsoft Windows Server 2008 R2 SP1 — apply KB4474419 exlink and KB4490628 exlink (an additional system restart might be necessary)

Microsoft Windows Server 2008 SP2 (x86 or x64) — apply KB4493730 exlink and KB4039648 exlink (an additional system restart might be necessary)

Microsoft Windows Small Business Server 2011 SP1 (x64) — apply KB4474419 exlink and KB4490628 exlink (an additional system restart might be necessary)

Microsoft Windows Small Business Server 2008 SP2 (x64) — apply KB4493730 exlink and KB4039648 exlink (an additional system restart might be necessary)

Upgrade your ESET product for Windows Server to the latest version.

We do not recommend using a version of the Windows operating system that Microsoft no longer supports. Security patches are not provided, and we cannot guarantee full protection.
