I just discovered the following warnings from the past 24 hours, over 100 of them, that all say the following:
"Security policies were propagated with warning. 0x534 : No mapping between account names and security IDs was done.

I did a "FIND /I "Cannot find" %SYSTEMROOT%\Security\Logs
\winlogon.
log" like it says to do, and it returned the following:
Cannot find IWAM_DD5RSV21.
Cannot find IUSR_DD5RSV21.
... those two are the only two results, repeated about 40 times. If I search through Active Directory for either one of those names, nothing is returned.
