Consolidation of MTS servers with different MDAC revisions to Win

Discussion in 'Server Migration' started by Chris Riediger, Jul 28, 2004.

  1. I am currently looking at some options for upgrading some NT 4.0 servers running MTS to a Windows 2003 platform. I am also looking at server consolidation opportunities while doing this upgrade.

    Basically, we have some MTS/COM apps written by 3rd parties which only work with specific versions of MDAC (varying from 2.1 to 2.7, and different Service Packs), each on a dedicated server. The servers are running Windows NT 4.0 (either SP 4, 5 or 6a).

    Is there a way to run multiple versions of MDAC on a Windows 2003 server? Even using virtual servers in some way would be acceptible. We need to get off NT 4.0 and we may not have an application re-write opportunity, so the migration may be as-is.

  2. Hi Chris,

    Thanks for your posting here.

    By default, MDAC in Windows Server 2003 is 2.7 (2.71.9030). We cannot run
    multiple version of MDAC on same box. The latest MDAC is 2.8:

    Download MDAC 2.8

    1. Visit the following Microsoft Web site:
    2. In the "Keywords" box, type "mdac" (without the quotation marks), and
    then click "Go".
    3. In the list of found files, click the first link "MDAC 2.8".
    4. In the upper right of the page that loads, click "Download".
    5. When the file download box appears, click "Save".
    6. In the "Save in" box, select "Desktop", and then click "Save".
