We have two Dell servers (running Windows Server 2003 SP2) with two broadcom cards that are teamed into one "BASP Virtual Adapters"
However, we have problems with this teaming.
Sometimes, on these servers (let's say it has an IP of 192.168.1.55) can not been seen from an external subnet (let's say 192.168.2.88) : which is a problem since our VPN is built that way and none of our overseas users can not access the applications on this server anymore... It can still be seen from a machine in the same subnet (same office in which the servers are), though.
After some investigation, I discovered that visiting an external website (like google.com) makes the server visible again. It is weird. For now, I wrote a script doing something similar (wget www.google.com
) as a scheduled task and launch it every few minutes as the problem keeps happening without any reason or recognizible pattern.
Really, something seems wrong : we received the machine this way from Dell and it happens on two servers, so it can not be an hardware issue with the network cards) : I already tried to upgrade the drivers, but the issue is still there. If I unteam one of the network cards, the problem is gone on the unteamed one but keeps happening on the teamed one.
Does anyone have experience with this Broadcom Teaming / BASP Virtual Adapter ?
It is the first time we actually use this system so maybe we missed something ?
If it can not be fixed, what is really the loss of this teaming anyway ? It sure is convenient to have a machine with several NIC referrable by a single IP address, but if we are to get rid of this teaming system, what would be the performance penalty ?
