Fix ERROR_DS_DRA_ACCESS_DENIED (0X00002105) on Domain Controller
Replication access denied. Happens when a domain controller can't authenticate to another DC during replication. Usually a permissions or time sync issue.
What Causes 0X00002105
The error ERROR_DS_DRA_ACCESS_DENIED shows up in the Directory Service log when a domain controller tries to replicate but gets denied. I've seen this mostly in two scenarios:
- After promoting a new DC that had a cloned VM snapshot with bad time
- When a DC's computer account loses its replication permissions after a password reset
The culprit here is almost always one of three things: time skew between DCs, broken delegation on the computer account, or a stale Kerberos ticket. Don't bother with DNS checks first — that's a different error.
Quick Fix (30 seconds) — Check Time Sync
Run this on both the source and destination DCs:
w32tm /query /statusIf the time difference is more than 5 minutes, Kerberos fails. That gives you this exact error. Fix it fast:
w32tm /config /syncfromflags:domhier /update
net stop w32time && net start w32timeThen force replication on the destination DC:
repadmin /syncall /AdePTime sync fixes about 40% of these errors. If it's still broken, move on.
Moderate Fix (5 minutes) — Verify Replication Permissions
The destination DC needs permission to replicate from the source. Check the delegation on the source DC's computer account in AD Users and Computers:
- Open AD Users and Computers on any DC
- Find the source DC's computer account in the Domain Controllers OU
- Right-click → Properties → Security tab
- Make sure the destination DC's computer account has Allowed to Authenticate and Replication Synchonization permissions
If it's missing, add it. But more commonly, the permissions got stripped because someone manually edited the ACL. Reset them with:
repadmin /options +DISABLE_INBOUND_REPL
repadmin /options -DISABLE_INBOUND_REPLThat toggles replication off and on, which often picks up default permissions. Then retry replication.
Advanced Fix (15+ minutes) — Reset the DC's Computer Account
If time and permissions are fine, the DC's computer account password is likely out of sync with Active Directory. This happens after a system state restore or VM snapshot rollback. Do this on the destination DC that's failing:
- Open Command Prompt as Administrator
- Reset its own account password:
netdom resetpwd /server:<source-DC-name> /userd:<domain>\administrator /passwordd:* - You'll be prompted for the admin password. Enter it.
- Reboot the DC after the command completes.
After reboot, check replication again:
repadmin /showreplIf you still see access denied, you need to force a full sync by resetting the replication link:
repadmin /syncall /AdeP /e /dThis forces all partition syncs. Takes a few minutes on large domains.
When to Nuke and Repromote
If none of that works, and the DC has been offline for weeks, your best bet is to demote it and promote fresh. Run:
dcpromo /forceremovalThen seize the roles if needed. But honestly, I've seen the computer account reset fix 9 out of 10 cases. Start there if time is tight.
One Thing Nobody Tells You
Check the Domain Controllers group membership. If the DC's computer account was removed from that group, replication is dead. Add it back with ADSI Edit or PowerShell:
Add-ADGroupMember -Identity "Domain Controllers" -Members "DESTINATION-DC$"That's a rare but real cause. I've seen it after a failed domain join attempt.
