## 5. Handle Reconnection Logic

### 5.1 Automatic Reconnection Handler
```java
package jcifs.internal.smb2.persistent;

import java.util.concurrent.CompletableFuture;
import java.util.concurrent.TimeUnit;

public class HandleReconnector {

import java.nio.ByteBuffer;
import java.util.UUID;

/**
 * Handle GUID structure for SMB2/3 durable and persistent handles.
 * Provides a unique identifier for each handle that can be used
 * for reconnection after network failures or server reboots.
 *
 * According to MS-SMB2, the GUID is a 16-byte structure with little-endian
 * byte ordering for the individual components.
 */
public class HandleGuid implements Serializable {

├── DurableHandleV2Request.java      - Durable handle v2 with timeout
└── HandleReconnector.java           - Automatic handle reconnection
```

#### 2.2 Implementation Tasks
- [ ] Implement persistent/durable handle contexts
- [ ] Add handle GUID generation and tracking
- [ ] Implement handle state serialization
- [ ] Create reconnection logic with handle replay
- [ ] Add timeout management for durable handles
- [ ] Implement handle lease association

    /**
     * The full path to the file or directory associated with this handle
     */

     */
    private final byte[] fileId;

                throw new IOException("Simulated reconnection failure");
            }
        }

    protected long durableHandleTimeout = 120000; // 2 minutes
    /** Maximum number of retry attempts for handle reconnection */

```

## 12. Future Enhancements

1. **Directory Leases**: Extend lease support for directories
2. **Lease Key Persistence**: Save lease keys for reconnection
3. **Parent-Child Relationships**: Implement hierarchical leases
4. **Lease Sharing**: Support lease sharing across handles

        // Resource state changed - may need to reconnect
        log.info("Resource change detected for: {}", notification.getResourceName());

        // Schedule reconnection attempt
        scheduleReconnection(getContext().getConfig().getWitnessReconnectDelay());
    }

    log.info("Resource change detected for: {}", notification.getResourceName());
    
    // Schedule reconnection attempt
    scheduleReconnection(1000);  // 1 second delay
}

private void handleClientMove(WitnessNotification notification) {
    // Server is asking client to move to different node
