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.
