Remote Differential Compression required or not? RRS feed

  • Question

  • I have some trouble with setting up Distribution Points on servers running Windows Server 2003 (non-R2). I found that the document "Supported Configurations for Configuration Manager" states that Remote Differential Compression is required for a DP (which does not exist in Server 2003 non-R2), but on the other hand the same document states that Server 2003 non-R2 is a supported OS for distribution points.

    Distribution Manager log says:

    Manager has not tried to install IIS component of operating system to distribution point "SERVER.DOMAIN" because its operating system is older than Windows Server 2008. Manual installation of IIS component of operating system to distribution point might be needed. Please ensure RDC is also enabled.

    So, what is now correct? Does it work without RDC on Server 2003, or is RDC required and hence it does not work on Server 2003?

  • Wrong assumption. Just have a look at the \Client folder of the primary site. It contains msrdcoob_x86.exe / msrdcoob_amd64.exe.

  • Site servers and distribution points require Remote Differential Compression (RDC) to generate package signatures and perform signature comparison. If RDC is not enabled, you must enable it on these site system servers.

  • Ok, so this means that this document is wrong when it claims in the "Operating System Requirements for Typical Site System Roles" section that distribution points can be installed on "Windows Server 2003 R2" or on "Windows Server 2003"?

  • Why should that doc be wrong? DPs can be installed on Server 2003.

  • DPs can be installed on Server 2003.

    But Server 2003 does not have RDC. RDC was introduced in Server 2003 R2. And above you said that RDC is required. Hence, no RDC, no Distribution Point.

  • Ahhhh! That should be stated somewhere!

    This MS document clearly says that RDC was introduced in Windows Server 2003 R2: http://msdn.microsoft.com/en-us/library/windows/desktop/aa373254(v=vs.85).aspx ... and I didn't find RDC as a downloadable update or as a component in Windows Server 2003.

    Anyway, thanks!

  •  I agree with torsten . Check this http://anoopcnair.com/2012/05/07/configmgr-sccm-2012-package-replication-issue-on-windows-2003-server-dp/

  • Ok .. it's not too easy to install a DP on a Windows 2003 server, but finally I've made it. I had to perform the following manual steps though:

    - install IIS including BITS (which can be derived from the prerequisites document though this is for 2008)

    - install RDC (\\<siteserver>\sms_<site>\client\i386\msrdcoob_x86.exe)

    - create WMI namespace (mofcomp \\<siteserver>\sms_<site>\bin\x64\smsdpprov.mof)

    - start the "COM+ System Application" service

    Except for the first step, I did not find this documented anywhere - had to collect this from various discussions.

  • Thanks for this info, I have non-working DP's on WS2003 and was struggling to find proper documentation of this setup.

    I'd already done the first two but didn't know about the second two.

    BTW On my setup, the smsdpprov.mof file was in the x64 folder (The x86 folder has only a bcd.mof). It parsed and ran without error on the 2003 servers.

    I'll post back later if these changes have made my DP's work.

  • OK, they still don't work.

    I did IIS, BITS, RDC, WMI Namespace, COM service as above. The DP OS is WS2K3R2 SE SP2.

    I still get "CSendFileAction SendFile failed 0x80041001" in the PkgTfrLog on the Site Server

    and

    "Failed to add file 'ccmsetup.cab' to content library. Error code: 0X80070002" in the smsdpprov.log on the DP server.

    I will upgrade (clean-rebuild) one of them to Server 2008, and post later in another thread if required.

    Sure, that was a typo. Fixed, thanks.
