SYMPTOMS
When you hot swap a network adapter or a virtual network adapter, you experience the following symptoms:
- Any other network adapters that share the same miniport driver in the computer are briefly removed from the system.
- Because of this first symptom, network traffic is interrupted. Additionally, programs that depend on network traffic may stop working or may generate error messages.
The actual symptoms may vary, depending on the system and programs that are involved.
Note When you remove a device and then install a replacement device of the same model in the same slot while the computer is running, this process is known as hot swapping. The operating system automatically recognizes the replacement device.
When you add Virtual Local Area Networks (VLANS) to network devices, you experience the following symptoms:
- VLANS on other network devices become disabled.
- The disabled VLANS show as active in Network Connections.
In this case, network traffic is interrupted.
CAUSE
When a network adapter is added or removed, the device driver's HaltHandler function is called for all network adapters, not just for the particular device that is being added or removed. This behavior also occurs when a network adapter is stopped and restarted to enable VLANs.
