What This Category Covers
Start by separating authentication, DNS, replication, secure channel, GPO, and permission failures. One user points to account state or permissions; one workstation points to DNS/time/secure channel; many systems points to DC, DNS, replication, or network changes.
First Layer to Isolate
User versus workstation versus domain-wide scope, then DNS/time/DC discovery/replication.
Useful Tools, Logs, and Portals
- AD Users and Computers
- dcdiag /replsummary
- repadmin /replsummary
- nltest
- w32tm
- gpresult
Before You Escalate
- User/device/domain scope tested
- DNS and time checked
- DC discovery confirmed
- Replication/SYSVOL/NETLOGON reviewed
