Warning Message During Small Business Server Upgrade

• Microsoft BackOffice Server versions 4.0, 4.5

SYMPTOMS

When you try to upgrade Microsoft Small Business Server (SBS) version 4.0 or 4.0a to SBS version 4.5, you may receive the following warning message:

WARNING: The version of Small Business Server you are installing only supports 40-bit encryption. If you continue, the encryption strength available to you will be reduced from 128-bit to 40-bit, and it may not be possible to recover full 128-bit capability. If you do not want your current level of encryption to be changed, you should cancel Setup at this time and run Setup again using a 128-bit version of Small Business Server. Do you wish to continue?

CAUSE

This issue can occur if you try to upgrade the 128-bit version of SBS to a 40-bit version of SBS. The warning is to inform you that your 128-bit encryption will change to 40-bit encryption if you choose to continue.

RESOLUTION

To resolve this issue if you want to return to 128-bit encryption, install Microsoft Windows NT 4.0 Service Pack 4.
