Anyone seen any issues with VLAN tagging on a Windows 2003 x64 machine? We are trying to move a NetBackup server from an x86 machine to an x64 machine and are having problems getting the multiple VLANs on a single NIC to work. We have had our network people check the Cisco trunking config 3 different times and they say it is right. Ping works to all VLANs. Tracert works to all VLANs and shows only the one hop as expected when going to a machine a VLAN that is tagged. RDP fails when connecting to a host on a tagged VLAN, but works when the target is on the default VLAN (or VLAN that can be reached by route on the default VLAN). Any ideas? We are using the most recent HP teaming NIC drivers with the 2 built in HP NICs teamed in a fault tolerant with preference config and the tagged VLANs are listed in the HP network configuration.
