    Hi all,
    I hvae just installed a SBS 2003, my server physically has 4G ram, but
    after installed, Windows shows only 3.12 G, why? Is that SBS doesn't support
    4G memory? I have 4 x 512 MB and 2 x 1G memory module, any one have ideas
    how to solve it?


    best regards,

  2. yes, SBS supports 4GB RAM, maximum. I personally reckon anything more than
    2GB is unnecessary in any but the most extreme cases. Another personal
    opinion is that people having more than 2GB in SBS seem to have wierd
    issues.

    However, SBS should recognise all that RAM. What motherboard are you using?
    Which slots is the RAM in? Have you tried just the two 1GB chips? Do they
    show as 2GB?

    I remember reading an article the other day that explained the solution to
    your problem exactly. I don't remember the Q number and I can't find it
    right now but it has to do with switches in your boot.ini file to tell the
    OS to use some extended areas for memory addressing. I'm sure you could
    find the article by searching TechNet for boot.ini articles.

  4. Note You do not have to use the /3GB switch on Microsoft Windows Small
    Business Server 2003-based computers. We do not recommend that you use the
    /3GB switch parameter in the Boot.ini file for Exchange Server computers
    that are also Active Directory domain controllers or global catalog servers.

    also discusses /PAE and /USERVA

    and if you plug '/3gb' into http://support.microsoft.com you may also see
    discussion of AWE

    none of which is relevent to SBS.

    Harry's new book also says you can "protect against hardware failure by
    using a striped array"

    (page 2-11 in the storage area)

    believe in who?

    Thanks all of you, I have solve the problem by adding a /PAE in the
    boot.ini, I don't understand why I have to add this switch, I only have 4 GB
    ram and SBS supports maximum 4GB...
