Microsoft wanted to make it easier for you to get its Small Business Server (SBS) suite up and running.
So when SBS 4.5 first shipped, the current Service Pack at the time was planned for slipstreaming into the base OS suite.
Service Pack 4 (SP4) for Windows NT Server 4.0 is also fully integrated into the setup for SBS 4.5.
This was done so novice small business consulting firms and administrators need not be concerned with applying the service pack. SP4 provides four main benefits to SBS 4.5 users.
Four Main Service Pack 4 (SP4) Benefits
1. Year 2000 compliance of Windows NT Server 4.0
2. Control of user profiles for users’ folders stored on the server
3. Support for the Euro currency symbol
4. Upgrade of the Point-to-Point Tunneling Protocol (PPTP) used for secure remote access over the Internet
SBS 4.5 and NT Server 4.0 Service Packs
The SBS 4.5 setup begins with an automated installation of NT Server 4.0 and Service Pack 3 (SP3).
There are several SBS server components developed specifically for SBS 4.0, and carried forward into SBS 4.5, that have system file dependencies on SP3. So even though SBS 4.5 requires SP4 to be applied both before and after the BackOffice Server applications are installed, SP3 is installed automatically and immediately following NT Server 4.0 installation.
Once the NT Server 4.0 portion of the SBS 4.5 unattended setup is complete and the unattended setup for the BackOffice Server applications is underway, SP4 is automatically applied to the SBS 4.5 system.
How Service Pack 4 (SP4) Factors into Other SBS Applications
With NT Server 4.0 and the integration of SP3, SBS 4.0 included a web server based on Internet Information Server (IIS) 3.0. This web server is required for, among other things, the HTML-based Manage Server console.
Through Microsoft’s limited time free Internet Technologies Offer Kit, SBS end users were able to get a free version upgrade to Proxy Server 2.0, a special SBS Proxy Server upgrade wizard, a white paper detailing the steps for the Proxy Server upgrade, and the Windows NT 4.0 Option Pack (NTOP).
Through the NTOP installation, SBS 4.0’s web server could be upgraded from IIS 3.0 to 4.0. Under SBS 4.5, the NTOP is integrated into the unattended installation so that IIS 4.0 is automatically installed as part of the standard SBS 4.5 setup routine.
