SBS: Services Do Not Work After Installing Service Pack 3

• Microsoft BackOffice Small Business Server versions 4.0, 4.0a

SYMPTOMS

After you apply Windows NT 4.0 Service Pack 3 (SP3) to a Small Business Server (SBS) version 4.0-based or 4.0a-based computer, you may experience performance problems and the following services may no longer function properly:

• Remote Access service



• Modem Sharing



• Fax Server



• Microsoft Internet Information Server 3.0 and 4.0



• Microsoft Proxy Server 1.0 and 2.0



• The Manage Server Console

CAUSE

This problem can occur after you manually apply Windows NT 4.0 Service Pack 3 to your SBS version 4.0 or 4.0a-based computer. When you do so, some SBS files are overwritten with incorrect versions.

RESOLUTION

To work around this problem, use any of the following methods:

• If Service Pack 3 has only been applied once and the "Create uninstall directory" option was selected during the installation, run Service Pack 3 Setup again and choose the "Uninstall a previously installed Service Pack" to roll back Small Business Server to the SBS-specific version of Service Pack 3.



• Restore a backup of your SBS computer made before you applied Windows NT 4.0 Service Pack 3.



• Reinstall SBS version 4.0 or 4.0a.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.
