Server Reboots and NICs show erratic behaviuor

  1. We have W2K8R2 SP1 RDS in our environment and they crash after a BSOD. After they reboot their NICs start behaving erroneously. When I try to open Network & Sharing Centre and try to open any NIC's properties the Network & Sharing Centre's windows gets hanged forever. I can't do any thing to the NICs from within the OS. Domain users can't login and get stuck at applying user settings......I plug out the ethernet cables from the Server's NICs and after a couple of hours the server gets fine. I again plug in the cables and all goes well but again within a week the servers do this crashing thing again. These servers have really got on my nerves. Have carried out all the preliminary checks and troubleshooting but no luck.

    I am uploading mini dump files of my 3 RDS.

    CNG.sys= Most likely kernel crypto framework is failing because you have bad system memory

    So how should I narrow down on the bad mem hardware?

    Make a bootable disk using Memtest86:
    http://www.memtest.org/
    Let each computer run for at least 7 passes.No errors are allowed...

    "As I mentioned earlier I have performed the preliminary checks which includes the memtest"... Did you run the latest version of Memtest86 (v4.20) for at least 7 passes?

    What exactly is "We have W2K8R2 SP1 RDS"...

    This looks like a hard drive fault...

    But why this problem is coming on all of my servers after upgrading to W2K8 R2?
    How to resolve this?
    I am uploading dump file of my another server. These dump files are 15 in number. Hope that you may get a better clue.

    All 15 of the minidumps are the same:
    Ntoskrnl.exe
    CRITICAL_OBJECT_TERMINATION
    Get in to Control Panel, System, advanced system settings, Startup and Recovery. Select small memory dump and check overwrite existing file. Un-check time to display operating systems.Turn off automatically restart while you are in there... Doing all this will speed up boot times, and stop the creation of duplicate minidumps. You say the BSOD's started after applying Windows Updates on all the 8 servers?

    Try a clean Windows install on one computer without the R2 SP1 update, and see if the computer runs stable

    Dumps are driver issues
    Dumps1 can be memory or hard drive issues
