When configuring ISL VLANS with a PRO/100 Intelligent Server adapter in Windows* 2000, communications to the vlan(s) fail.
A problem was discovered in the vlan driver that is contained in the 100VW2K.EXE archive that prevents ISL VLANS from working properly on Intel® PRO/100 Intelligent Server Adapters. A workaround is provided below and the next release of drivers will contain the fix. This applies to the following driver versions: e100snt5.sys v2.30 ivlanw2k.sys v 2.27 prosetp.cpl v3.142
1Regedit is a Microsoft utility and can render a system unstable. See Microsoft for warnings on using regedit.
- Update the driver for the Intelligent Server Adapters with the drivers contained in 100VW2K.EXE on the support.intel.com Web site. This will install PROSet and the ivlanw2k.sys drivers that are required to configure and use vlans.
- Using PROSet, configure the vlans.
- After updating the driver and configuring the vlans, use regedit1 to add a new dword value "DontUseMulticastAll" and set the value to 1 at location HKLM\System\CurrentControlSet\Services\iVLANProtocol\Parameters\Adapters\<adapter id>\, where <adapter id> is a long string of letters and numbers. There will be one of these for each physical adapter that is configured for VLANs. The setting needs to be in all of them.
- Restart the system.
