# Configuring VLANs in Microsoft* Windows*

In Windows, you must use Intel® PROSet to set up and configure VLANs. For more information, select Intel (R) PROSet in the Table of Contents (left pane) of this window.

The following versions of Microsoft* Windows support Intel PRO adapters when configured for VLANs:

- Windows NT* 4.0 (with Service Pack 6a or later)

- Windows 2000 (with Service Pack 4 or later)

- Windows XP Professional

- Windows Server 2003

In most environments, a maximum of 64 VLANs per server can be set up.

Intel PRO Adapters do not support VLANs on Windows 98 or Me.

In Windows 2000 and XP, you cannot re-enable a VLAN once it has been disabled. To re-enable the connection, disable all adapters, then restart the server.

| CAUTION: Use Intel PROSet to add or remove a VLAN. Do not use the Network and Dial-up Connections dialog box to enable or disable VLANs. Otherwise, the VLAN driver may not be correctly enabled or disabled.
