FRS event ID 13526 occurs when a domain controller becomes unreachable. This problem occurs because FRS polls Active Directory at regular intervals to read FRS configuration information. During the polling, an operation is performed to resolve the security identifier (SID) of an FRS replication partner. The binding handle might become invalid if the bound domain controller becomes unreachable over the network or restarts in a single polling interval (default 5 minutes).
To resolve this issue, restart FRS on the computer logging the error message.
