The Windows Firewall is on and does not have exceptions configured for SQL Server or the TCP ports that are required for intersite data replication. To resolve this issue, allow sqlservr.exe or the TCP ports to be accessed remotely. By default, SQL Server listens on TCP port 1433 and the SQL Broker Service uses TCP port 4022, but custom ports might be configured.
