# Configuring VLANs in Microsoft* Windows*

In Windows, you must use Intel® PROSet to set up and configure VLANs. For instructions, see the Intel PROSet Help. To access Help, open Intel PROSet and click the Help menu at the top of the screen.

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

- 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.
