Hi,

I have read in the MS documents that the Passwords of accounts that are
specified in the PRP are allowed to cache their credentials.

Now where is this cache? Is it the physicsal memory space or AD DB
(Read-only)

Will 64- bit add any value to RODC's?

They're stored in the database of the machine. It's not just physical
memory - it's the DB.

64bit is always helpful for Active Directory though you'll likely notice
the benefit of 64bit only in larger directories with a larger database
(> 2 GByte of a DIT). The largest benefit probably is with directory
searches and the global catalog.

As every server that you purchase today comes with x64 hardware, it'd be
silly to not install a x64 version of Windows and use its capabilities.

Cheers,
Florian

Hello carl,

As Florian stated it is stored in the RODCs database in a not readable format.
If you have the possibility to go with 64bit, i also suggest to do it. All
new and upcoming OS/Server versions will come only as 64bit version.

Best regards

Thanks!

Apart from the inherent benefits of a 64-bit OS, are there any specific
benefits that a 64-bit RODC brings to the table?

Hello carl,

Did you read this here to understand why/where using a RODC:
