Registry value must match a "bitwise and" comparison to 1024

    Question

  • Making a computer secure, it requires that "Windows must be configured to block application execution if certificate server status is unavailable." The solution goes through a walkthrough of changing the registry to have the State value "match a 'bitwise and' comparison to '1024'". Tried multiple combinations to get it to work, to no avail. Any help on configuring this would be great!

    Thanks!

    Which solution?

    This simply means that Bit 10 has to be set to 1. Usually done via
    something like "NewVal = ExistingVal Or 1024" (depending on your
    scripting language, of course).
     
    It cannot be done via native Group Policy, anyway.

  • Gotcha. The solution is the one suggested by the security checker. It says to do it via the regedit, but it wouldn't appear as though that works. 

    If 1024 would be equal to bit 10, what would bits 2048, 4096, 8192, 131072 and 65536 be equivalent to? Bits 11, 12, 13 etc?

    Thanks for the help!

    Missed a class in maths? :-)
     
    2^10=1024
    2^11=2048

  • Did you solve the issue?

    I've put 65536 for all keys, but with no good results.
