Resolving the This DNS Record Already Exists Error in Plesk for Windows

Scope: Plesk Obsidian 18.x (Windows Server 2016/2019/2022) with Microsoft DNS.
Applies to: Adding a domain, sub-domain, or domain alias that fails with:

Unable to create the domain example.com because a DNS record pointing to the host example.com already exists.

1. Why This Happens

Root Cause	Database Table	Symptom
Orphaned DNS zone left after deletion	dns_zone	Domain isn't listed in Websites & Domains, but SELECT id FROM dns_zone WHERE name='example.com'; returns a result.
Duplicate DNS record exists	dns_recs	A or CNAME record for the same hostname (e.g., multiple www records) causes conflict.
Domain alias still present	dom_aliases	SELECT name FROM dom_aliases WHERE name='example.com'; returns a row; domain can't be added again.
Domain is under another subscription	domains	Domain exists in a hidden or forgotten subscription; must be removed or renamed first.

The Plesk GUI only shows domains under active subscriptions. PSA database entries outside of that still block new domains.

2. Prerequisites & Safety First

Admin access via RDP to the Plesk server
Plesk CLI tools available in PATH (%plesk_bin%) or via full path
Backup the PSA database before making changes:

plesk db dump psa > C:\psa_before_dns_cleanup.sql

3. Fast-Track Flowchart

 Add domain 

 
Check orphaned zone: SELECT id FROM dns_zone...
 
If zone exists Try: dns.exe --del-all
 
Fails DELETE FROM dns_zone...
 
Check dom_aliases
 
Delete alias Add domain 

Skip to Section 5 for CLI-based removal.

4. Fixing Through the GUI (For Simple Cases)

Check existing DNS zone records:
Go to Websites & Domains example.com DNS Settings Remove duplicate A/CNAME records.

Check Domain Aliases:
Websites & Domains Domain Aliases Find example.com Remove.

Re-add the domain: Only use apex (example.com). Plesk auto-creates the www alias.

Still seeing the error Move on to the CLI cleanup.

5. Deep Dive - Resolve Conflict via CLI

Always use elevated Command Prompt (cmd.exe) and quote paths containing spaces.

5.1 Check if Zone Exists

plesk db "SELECT id FROM dns_zone WHERE name='example.com';"

If a row is returned, proceed to remove the zone.

5.2 Attempt to Wipe Records

"%plesk_bin%\dns.exe" --del-all example.com

If successful: Zone wiped.

If this fails (returns unknown parameter or does nothing), skip to 5.3.

5.3 Delete the Entire Zone via SQL (Guaranteed Fix)

plesk db "DELETE FROM dns_zone WHERE name='example.com';"

5.4 Refresh DNS Config

"%plesk_bin%\dnsmng.exe" update *

5.5 Check & Remove Domain Aliases

plesk db "SELECT name FROM dom_aliases WHERE name='example.com';"

"%plesk_bin%\domalias.exe" --delete example.com

5.6 Re-Add the Domain

Go to Websites & Domains Add Domain:

• Domain name: example.com

• DNS service: Enabled

Confirm DNS Records:

• A example.com IP

• CNAME or A www example.com

Done!

6. Special Cases & Troubleshooting

6.1 External DNS Sync

Disable zone sync temporarily if syncing from a slave server to avoid auto re-creation.

6.2 Check for Hidden Subscriptions

plesk db "SELECT name,id FROM domains WHERE name='example.com';"

If found, remove or rename domain in that subscription.

6.3 Still Failing Try Plesk Repair Tool

plesk repair dns example.com -y

Or if needed:

plesk repair all -y

7. Best Practices to Prevent This Error

Always add apex domain (example.com) first. Plesk auto-creates www, mail, and related records.
Use the GUI to remove domains & aliases when possible - this clears all dependencies.
Run regular cleanup checks:

"%plesk_bin%\dbclient.exe" --direct-sql --sql="SELECT name FROM dns_zone dz LEFT JOIN domains d ON d.dns_zone_id = dz.id WHERE d.id IS NULL;"

Track subscription ownership to avoid ghost records.

8. FAQ

Q: Can I reset instead of deleting a zone
A: dns.exe --reset example.com -ip x.x.x.x only works for zones tied to active domains. For orphans, SQL deletion is required.

Q: Is the process different on Linux
A: Same logic applies; use plesk bin dns instead of dns.exe, and Linux will use BIND instead of MS DNS.

Q: Will this break DNS temporarily
A: Yes--only proceed if it's safe to reset or recreate the zone immediately.
