Message: The attempt to establish a replication link to a read-only directory partition with the following parameters failed.

Directory partition: %1
Source domain controller: %4
Source domain controller address: %2
Intersite transport (if any): %5

Additional Data
Error value: %6 %3

   
Explanation

The Knowledge Consistency Checker (KCC) created a connection object between two global catalogs or between a global catalog and a domain controller, but the KCC could not turn the connection object into a replica link because the remote server is not responding.

Possible causes include:

  • The computer is disconnected from the network.
  • DNS could not resolve the server name.
  • The target account could not be found.
  • Access was denied.
  • A database error exists.
   
User Action

Verify that there is connectivity between the two global catalogs or the global catalog and the domain controller. The KCC will try to create a link automatically the next time it runs.
