Hi there,

I have an older IBM server running Windows server 2003 standard.  I currently has 1 ethernet port running at full speed 1Gbps.  It is connected to a gigabit switch which is what all the other users are connected to.  Some users have complained that the network is slow at times when everyone is on.  All computers have gigabit cards and are running at full speed.  Is there a way to improve network access to this server by adding an additional ethernet card gigabit card and then bridging them in a load balancing mode?  Would that help and how do you set this up once the card is installed?

I don't think the cause of the issue is NIC. Did you check Disk IOs, CPU loads, Memory during busy times, how are they? May be you need to do some upgrade on these components instead of adding another NIC.
For your question whihc is Network Load Balancing please check the following link

Adding a second NIC will not improve the speed of the network.  This is most likely caused by other issues on the network.  Our servers have dual NICs which are teamed to provide redundancy and load balancing; however users still complain about slow network issues during busy times.  By setting up wireshark and monitoring your network traffic you may be able to identify the real issue.
