Very Very slow WDS pxe-process

    Question

  • Hello,

    when i try to deploy a VM using WDS/MDT the startup for contacting the WDS-server is very slow :

    The WDS-server is a Server2012R2 (not preview)-server. 

    I have reinstalled WDS already but nothing will help.

    Anybody with a solution?

    Thx

  • Not sure, but how DHCP and gateway have same IP?

  • DHCP/Gateway is not problem. This wasn`t a problem in server2008r2. This is my router.

    This is the exact error which i can`t fix :

  • I have just created a seperate WDS-server on server 2008r2 instead of Server 2012R2.

    When booting from this servers within the SAME domain and SAME settings the PXE-boot is working!

    Why isn`t the pxe-boot working on server2012R2 :

  • On server2012R2 there is one extra tab on wds:

    0 en 512 are not working.

    Anybody with an option?

    Thx

  • Problem solved by disabling "enable variable windows extension" and set the maximum block size to the maximum.

  • Enable WDS Server logging and report back. http://technet.microsoft.com/en-us/library/cc732729(v=ws.10).aspx

    If that does not work, it could be your network is not forwarding the correct PXE requests.

    Can a computer on the same segment connect to the WDS Server? Or is it only computer on different segments.

    Finally, you could do some network sniffing :^

  • Hi Keith,

    i have checked your options, but no extra info came out.

    When i enable the WDS-server on a Server 2008R2 with SAME settings, pxe boot is working ok from that server with the same cliënt.

    The only difference between server 2008R2 and Server2012R2 is the option "TFTP" --> "Blocksize" and "Variable Window Extension".

    I think the solution is in this part of WDS, but i didn`t find it.

  • Anybody?
    Wednesday, November 06, 2013 7:57 AM
  • As I understand you moved your WDS from server 2008 to server 2012. Did you move MDT stuff as well?
    Wednesday, November 06, 2013 2:35 PM
  • Hi,

    the location of the MDT-server doesn`t matter.

    A separate WDS server (2008R2) is working well, but wds in server2012R2 not..

  • If MDT doesn't matter why did you post under MDT forum? You should go to Server forum, no?

    ;-)

    OK check your Boot Server IP in your DHCP server:

    - Open your DHCP nodes
    - Go to Server Options container
    - Check the 066 Boot Server Host Name value

    Is there the IP of your Server 2012 WDS ?

  • Hi Acetik,

    my DHCP-server is my router (not microsoft).

    This is working well for years (with Server2008 and Server2008R2) but not with Server2012r2.

  • You should report in the server forum in my sense.
    Thursday, November 07, 2013 10:31 AM
  • I have just tested the following:

    1 MDT2013-server --> Using this litetouch.wim for all servers

    1 Server2008R2 --> No problem with PXE-boot

    1 Server2012--> Specified error from the beginning of this thread

    1 Server2012R2 --> Specified error from the beginning of this thread

    So, the problem is with server 2012 and server2012R2 pxe boot. The only difference in the Interface is the Tab "TFTP". But i didn`t find a solution. Anybody who can test this out?

    Thx

  • To make sure the router/dhcp-server isn`t the problem, i installed a Microsoft-DHCP-server and did a pxe boot.

    Still same problem :

    So what to now?

  • There are two configuration options for Windows Deployment Services. It can be configured to integrate with Active Directory or be configured as a standalone server.

    May help you

  • I have checked those settings, but these aren`t the problem. These settings are the same as on server 2008R2. From server2008R2 i do not have these pxe-boot problems.
    Thursday, November 07, 2013 2:51 PM
  • On the windows server2012R2 i have enabled ALL windows deployment services-logs (including verbose and admin).

    I can see a lot of traffic between cliënt and host, but i don`t see errors or maybe the problem.

    Only this error :

    [WDSServer] [base\eco\wds\wdsmgmt\src\wdsdirectoryservicesusepolicy.cpp:306] Expression: , Win32 Error=0x2

    Anybody with an option with this kind of logging?

    Thx

  • We are here to assist you with guidance, if you are still having problems figuring out what the root cause is, then you might have better luck contacting Microsoft Product Support Services. It's good that you have enabled logs, but with timing issues, it's not necessarily the errors, but also the timeouts. What is causing the delay in response? It could be that the PXE server is trying to contact your DC, however your DC is overloaded, so it's slow in responding. For complex issues like this, there is no silver bullet.

    At this point, AcetiK  is correct, if the problem is that the PXE server is not responding, then this is *NOT* a MDT issue, this is a Windows Server WDS issue. Best to post on the Server aliases, or ask Microsoft Support.
