• Demonstration: Installing and Configuring a WINS Server

When Is WINS Required?

WINS is required for the following reasons:
• Older versions of Microsoft operating systems rely on WINS for name resolution
• Some applications, typically older applications, rely on NetBIOS names
• When you need dynamic registration of single-label names
• If users rely on the Network Neighborhood or My Network Places network browser features
• If you are not using Windows Server 2008 as your DNS infrastructure
WINS Client Registration and Release Process
1
• WINS client sends request to register
• WINS server returns registration message with TTL value, indicating when the registration expires
2
• WINS client sends request to release name
• WINS server sends a positive name release response
What Is Burst Handling?
Burst handling allows a WINS server to handle a high number of simultaneous name registration requests
1-WINS client registrations exceed the burst queue threshold
2-WINS acknowledges registrations with a short renewal interval
WINS Server Name Resolution Process
1-Client makes three attempts to contact WINS server, but does not receive a response
2-Client attempts to contact all WINS servers until contact is made
3-If name is resolved, IP address is returned to the client
Demonstration: Installing and Configuring a WINS Server
In this demonstration, you will see how to install the
WINS server feature and configure burst handling
Lesson 2: Managing the WINS Server
• Overview of Client Records
• Demonstration: Filtering and Viewing Records in WINS
• How Scavenging Works
• Deleting WINS Records
• Backing Up and Restoring the WINS Database
• Compacting the WINS Database
• Demonstration: Managing the WINS Server Database
Deleting WINS Records
To delete obsolete records, you can update the WINS database by:
• Simple deletion. Records selected by using the WINS console are removed from the current local WINS server
• Tombstoned deletion. Records are marked for deletion, replicated to other WINS servers, and then removed during the next scavenging operation
Compacting the WINS Database Maintain WINS database integrity by using:
• Dynamic compacting. Automatically occurs while the database is in use
• Offline compacting. Administrator stops the WINS server and uses the Jetpack.exe command-line tool
Compacting recovers unused space in a WINS database
