What you’re seeing
- DFS Replication Event 2213 saying replication has stopped on a volume after a dirty shutdown.
- Group Policy changes apply at one site but not at another.
- Logon scripts or policy files differ between domain controllers.
- Event logs show DFSR warnings starting at the time of a power outage or forced restart.
- Group Policy results report errors reading policy files from SYSVOL.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- The domain controller shut down unexpectedly, and DFS Replication paused to protect its database from possible corruption.
- The server is set to wait for an administrator to resume replication rather than recover automatically after a dirty shutdown.
- A failing disk, storage controller or UPS issue caused the unclean shutdown in the first place.
- Replication had already been paused for a long time, so the content is now out of date compared with the other DCs.
Why it matters
SYSVOL holds the Group Policy settings and logon scripts that configure every computer and user in your domain. When it stops replicating, security settings such as password rules, firewall policies and software restrictions apply inconsistently depending on which DC a computer contacts. That creates both support headaches and compliance gaps. If replication stays paused too long, recovering safely becomes more complicated, so this should be handled promptly.
How AskTechGurus fixes it
Skip the trial and error. A certified engineer works on your actual system, finds the root cause, and fixes it properly.
Tell us what’s happening
Submit a ticket in about two minutes. Paste the error, describe what changed, and pick your tier. No charge to submit.
A certified engineer diagnoses it
A vetted, US-based systems engineer claims your ticket, usually within minutes during business hours, and investigates over a secure remote session you can watch and end at any time.
Fixed and verified with you
The engineer resolves the root cause and confirms with you that it’s working. You don’t just get a workaround, and you get a plain-English summary of what was wrong.
Pay only when it’s resolved
Fixed price from $99, invoiced only after you approve the fix. If it isn’t resolved, you don’t pay.
Frequently asked questions
Is anything lost because of the outage?
Usually not. DFS Replication pauses to protect data rather than discarding it, though some newer policy changes may not have reached every server yet.
Why didn't it recover on its own?
Windows is often set to wait for an administrator after an unclean shutdown so that a potentially damaged database is not replicated. That's a deliberate safety choice.
Should we worry about the power outage itself?
It's worth reviewing. A UPS that didn't shut the server down cleanly can cause this again, and an engineer can tell you what the logs show.
