Hi to all!

I tried to upgrade from Windows XP Pro to Windows Server 2003 Enterprise Edition,

A message box appears with the following message:
16 bit MS-DOS Subsystem,
E:\i386\winnt32.exe
The NTVDM CPU has encountered an illegal instruction.
CS:06b8 IP:e7e7 OP:63 b7 14 00 00 Choose 'Close' to terminate the application.

Then I start the computer using Boot disc and try to install from there, when I execute the Winnt file the message appears saying that the 'program is too big to fit in memory'.

I don't know what causes this problem, could someone help me on this.

Computer details:
AMD Athlon(tm)XP 1700+1.46 GHz
384 MB of RAM
Microsoft Windows XP Professional
Version 2002 Service Pack 1
