NLB settings could not be configured. Unexpected error [0xC004352] RRS feed

  • Question

  • I have setup a 2 node UAG Array setup and want to setup NLB on the External NIC


    I have my array setup but when I try to register UAG and pick the external virtual IP, it keeps bombing out with the error:
    "NLB settings could not be configured. Unexpected error [0xC004352]"


    I setup my standard VMware vSwitches to allow MAC changes and promiscuous mode is allowed.. (ie I saw the doc where HypverV VMs must be marked allow MAC changes)

    I tried my VMs on the same host and hence same vSwitch and on different hosts (via an external Dell 2724 switch) still got the same error..

    I tried multicast, unicast and IGMP Multicast either way I get the same error..

    I can tell NLB is never loaded on the inside NICs nor is the VIP set on the inside NICs.
     
    I saw some of the other posts re: this error and am 100% sure I am setting the NLB VIP the UAG GUI on the external NICs


    I do have my internal and external NIC setup w/ 2 inside IPs on each UAG array member based on this document and plan to publish UAG Ext NIC via a external FW rule:
    http://social.technet.microsoft.com/wiki/contents/articles/how-to-install-uag-for-application-publishing-on-a-single-network.aspx

    I tried running NLBclear.exe as outlined below, that didnt seem to help anything.

    This doc might show more of the error:

    FPC_ERR(0x352)
    0xC0040352
    The specified Virtual IP address (VIP) <VIP> is not contained in the <NetworkName> network, in which the Network Load Balancing cluster resides.

    What am I doing wrong? 
    What other logs and I go inspect etc?  
    The NLB settings you do in the WebManager to start NLB is all after the configuration is applied from the UAG GUI correct?

  • I'm not sure, from your explanation, whether you are configuring NLB from within the UAG interface, or somewhere else. On a UAG server, all the configuration is done directly from within UAG's Admin/Network Load Balancing. If you made any configurations directly in Windows, or in TMG, this may be the cause of your problem, as it can cause a serious conflict. If this is not the case, please tell me if you got this error as part of the NLB configuration page, or during an Activation of UAG?

    Can you provide some detail on your IP addressing and what actual VIP address you are trying to define?

    Are both UAG interaces connected to the same network/subnet?

    Cheers

  • JJ,
    Yes both UAG interaces connect to the same network>

    UAG01  Inside=192.168.1.205    Outside= 192.168.1.204 
    UAG02  Inside=192.168.1.207    Outside= 192.168.1.206
    Masks 255.255.255.0
    Outside NICs GW 192.168.1.1
    Inside NICs GW = <none>
    Inside NICs DNS = <internal DNS IP>
    Outside NICs Metrics = 500  (per the doc)

    Ben,
    I did the config from within the UAG GUI, until the point of fustration set in and attempted to manually configure NLB as I never saw NLB even being configed on the NICs after pushing the GUI config form UAG.   That didnt work so I cleared out all my settings and then used the NLBclear.exe as well.  The error happens when I try to push the config.

    Is there some problem having both nics on the same interface per Kevin Saye/ Ed Price (both from MS) blog post. 
    http://social.technet.microsoft.com/wiki/contents/articles/how-to-install-uag-for-application-publishing-on-a-single-network.aspx As that blog post doesnt actually show NLB being setup, but they setup an UAG array.

    Thanks guys.

  • Hi Johanthen,

    Did you solve the issue?
