Those DELL's with the 3com nic's have so many problems! There's a thread over in comp.dcom.sys.cisco with someone else having problems with the same PC's and NIC's.
Usually the 3c509's are OK. I remember the 3C509B's as being rock-solid. How fast are the PC's booting to beat portfast? Or are the NIC's some sort of boot on lan client, where the NIC get's taken over before the OS even loads. Maybe someone can disable the wake on lan feature if those DELL's have it, because otherwise I can't imagine a NIC caring about network connectivity before the OS kernel wakes up and takes over the NIC anyways.
