1A First Alternative

Import 1A root certificate - Windows XP

Microsoft has ceased security support for the Windows XP operating system in May 2014. This means that Windows XP PCs will no longer be safe to use.

Please contact your 1A partner to obtain a more recent operating system or a new PC.
This manual is for older systems and/or software and is no longer maintained.

This manual is meant for 1A-server users with a servername which ends in nl.alt001.com. This manual explains how you can install the alt001.com root certificate, so you can use the services on your 1A-server without certificate warnings.

Certificates are used to identify services and to encrypt the communication to and from the service. When a certificate is not trusted, this encryption will not work.

Every 1A-server contains an email server that accepts both encrypted and unencrypted connections. Because unencrypted servers are attacked more often, they will be phased out. Browsers also show a warning when an unknown certificate is used
