Sif-oidak was documented as a hybrid AD/M365 environment. It is not: there is no
Entra Connect on either DC, no AD object carries msDS-ConsistencyGuid, and every
M365 user has onPremisesSyncEnabled=null. AD and M365 are disjoint, and email is a
third system entirely (sifoidak.com at GoDaddy; the O365_BUSINESS SKU carries the
EXCHANGE_S_FOUNDATION no-mailbox stub).
That mismatch caused a real failure: Dwayne Ortega had a cloud account only, so he
could not log in to a domain-joined workstation. Created his AD account and recorded
the two-account onboarding rule.
Also documented: printer error 740 (Point-and-Print driver install needs admin,
UAC prompt never surfaces), a GPO pushing the MX-6240N queue from the wrong server,
SIF-SERVER2 confirmed as a backup DC, and refreshed stale laptop agent UUIDs.
