<div>
Your boot file should be changed to:<br />
[boot loader]<br />
timeout=30<br />
default=multi(0)disk(0)rdi<wbr />sk(0)parti<wbr />tion(1)\WI<wbr />NDOWS<br />
[operating systems]<br />
multi(0)disk(0)rdisk(0)par<wbr />tition(1)\<wbr />WINDOWS=&quot;W<wbr />indows Server 2003, Enterprise&quot; /noexecute=optout /fastdetect /PAE
</div>

<div class="content wysiwyg-content">
i have recently upgraded a server with server 2000 advanced installed to server 2003 enterprise.<br />
the server previous to upgrade had 8gb ram, and this was recognised within windows, now after the upgrade the system only see's 3.68gb of ram? yet on the bios the 8gb is shown!<br />
<br />
can anyone advise why this may be the case? as i assumed that enterprise 2003 should see the 8gb without any tweaking!

Server 2003 Enterprise only seeing 3.68GB of possible 8GB ram

Components are those devices that are internal to a computer -- the PC boards, the central processor (CPU), the memory (RAM), disk and video controllers and so on.

Components

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Server Hardware

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
