Dual NICs on a Domain Controller - mysterious problems

I have a dual DC W2k domain, and my main DC which holds all but the Schema
Master and is also a GC, also has dual NICs. These dual NICs are bridged. I
have them plugged into 2 separate modules of an HP ProCurve 5308xl switch.
One plugs into module A and the other plugs into module H on the switch. Any
ideas if this is adequate? Most of the time all is wel, but I seem to get
hit by a broadcast storm more often than I should and am hoping to rule
anything out if possible.

Many thanks.
 
Bridging the Nics makes the PC become a "2-port Switch",...you can't plug
two ports from the same Switch in to another same Switch unless both
Switches run Spanning-Tree Protocol. When they run STP, it will determine
the "faster" of the two links and will shutdown the slow one and use it as
fail-over of the first link goes bad. If they do not run STP, then you do
nothing more than create a "mess" called a Layer2 Loop.
 
You don't want to bridge the nics but adapter team them. If ibm gigabit nics
the teaming software is part of Proset. This way you have one ip address on
the nics and teaming creates one virtual pipe of 4gigabit.
