# Configuring IEEE VLAN in Microsoft* Windows*

| CAUTION: In Windows 2000 and NT4, you must use the Intel® PROSet II control panel utility 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.
| NOTE: In Windows 2000, you cannot re-enable a VLAN once it has been disabled. All adapters must be disabled first. Then the server must be restarted to re-enable the connection.
| NOTE: In Windows NT 4.0, VLANs require Service Pack 6a or later.

Follow these steps to join a VLAN in Windows:

Create a VLAN on the switch. Use the parameters you assign there to join the VLAN from the server. See your switch documentation for more information. Start Intel PROSet II as described in Using Intel PROSet II. If your computer has multiple adapters, right-click the desired adapter from the pull down list in Intel PROSet II. Note that VLANs can be assigned to a team, but teams should be set up before VLANs. From the pop-up, choose Add VLAN. You may see a dialog asking you to enable 802.1Q tagging. This is required for VLANs. Click YES to enable the tagging if you see this dialog. Enter the VLAN ID and VLAN Name. The VLAN ID must match the VLAN ID on the switch. Valid ID range is from 1-4094. The VLAN Name is for information only and doesn't have to match the name on the switch. Click Join VLAN. Repeat steps 3-5 for each VLAN you want the server to join. The VLANs you add are listed in the Installed VLANs box and in the Windows Device Manager. Finish the wizard and click OK to close Intel PROSet II. The OS will direct you to set the address(es). Restart the computer if prompted.
