What does Windows error code 4006 (ERROR_RPL_NOT_ALLOWED) mean?

ERROR_RPL_NOT_ALLOWED

Replication with a nonconfigured partner is not allowed.

ERROR_RPL_NOT_ALLOWED is Win32 error 4006 (0xFA6) and belongs to WINS replication partner policy.

Where the result appears

• Pull or push replication between WINS servers.
• Manual replication initiated from administration tools.
• A newly introduced server contacting an existing WINS topology.
• Legacy disaster recovery using an unregistered partner.

Likely causes

• the remote server is not configured as an allowed replication partner.
• partner entries disagree about push, pull, or address identity.
• a server was rebuilt with a new address but old partner configuration remains.
• an unauthorized host attempted the WINS replication protocol.

Troubleshooting steps

• Record local and remote partner lists.
• Record push/pull settings and configured addresses.
• Record server owner IDs and database versions.
• Record network trace or WINS replication events.
• Record recent rebuild, address, or topology changes.

What to verify

Verify whether the remote server is not configured as an allowed replication partner. Check local and remote partner lists together with push/pull settings and configured addresses.

Handling, retry, and recovery

Add and validate the partner through supported WINS configuration only when the relationship is intended. Otherwise keep the rejection and investigate the unexpected replication source.

Difference from nearby codes

This is a policy/configuration rejection, not a transient transport failure between already configured partners.

Practical example

A replacement WINS server uses a new IP address while peers retain the old partner entry. Updating both sides restores authorized replication.
