You simply need to calculate the bitwise value there is a calculator online to do this:
http://www.miniwebtool.com/bitwise-calculator/?data_type=10&number1=524288&number2=524288&operator=AND

I assume you know how to set the registry value ?

Yes.  We're STIGging a Windows 7 laptop which requires quite a few registry changes.  This 'bitwise and' issue threw us for a loop.  Hadn't seen that one before.  Not much info in Google either....

The issue isn't resolved yet.  Trying to set a registry key in HKLM\System\CurrentControlSet\Control\LSA\MSV1_0 on the NTLMMinServer.  Instructions are: 'value must match a 'bitwise and' comparison to '524288', and 'value must match a 'bitwise and' comparison to '578636456'.  I have space for only one answer.  If I put the value in the key as 524288, the finding fails because the 57836456 reading shows false.  If I put the value in the key as 57836456, then the finding fails because the 524288 value is not there.  I've tried adding them together with no luck.  Any assistance would be appreciated.

Ok so I am not sure what you are trying to do here, but the hives here deal with authentication.

Are you trying to follow instructions of some sort to resolve an issue, or are you just doing this as a test exercise  ?

There are two keys here which could match inserting the values you indicated:
NtlmMinClientSec
NtlmMinServerSec

The expectation I am sure is to add one value to server and another to client.

Please double check your instructions.


Incidentally your initial question has already been answered.
