Broadcom BCM 57810S with integrated MAC/PHY
Yup that's a broadcom.
1. ensure latest network drivers are installed
2. ensure latest bios etc etc
3. Disable rss/toe/VMQ unless you can prove to yourself that those
actually work as advertised

You sure those suckers aren't evil Broadcoms?
Dunno, I didn't set up the hardware, one of the other guys did, I just
dcpromo'ed it. i suppose they could be ... one of them is a blade,
using their "FlexFabric 10G 2 port 534FLB" adapter.
I rolled out the VMs.
All the servers that dropped out of DNS all point to DC#5 (VM) and
DC#6 (HP physical, the blade mentioned above).
As a specific example:
DWB019 has a static IP address, and the above 2 servers as it's DNS
settings. No manually created A records created in DNS, we just let it
register. Up until this morning, all was well.
(last Thu, we changed the DNS settings to point to #5 and #6, it's
current DNS settings (both Win2012 R2), from the older DC#1 and #3 - a
physical and virtual Win2008 R2. Did not reboot, flush DNS, etc - we
just changed the DNS settings on the NIC)
DC #5 and DC #6 have been DCs for the last 2-3 weeks, and have been
DNS servers. We just hadn't pointed any clients directly at them, to
use as their DNS settings on their NICs.
This morning, there is no record of DWB19 in DNS at all. I go to
DWB019, open an elevated command prompt, do "ipcofig /registerdns",
and then there is a record in DNS, timestamped this morning at 10AM.
So why did it drop out of DNS over the weeked? And why didn't it renew
itself, especially if a manual register works just fine?
And how do I stop it from doing that again?

Virtual or real metal?
Both. 2 virtual, 4 physical. :-) The "main" DNS server, the ones
almost all the servers point at (and therefore should be registering
with), is virtual. The physicals are 2 Dell and 2 HP boxes.
Nics are Intel or Evil Broadcoms (TM)?
The virtuals are all vmxnet3, the Dell physicals have teamed Broadcom
NICs and the HP has their NIC teamed.
(if virtual and if Evil Broadcoms (TM) ensure you have disabled rss/toe
and
VMQ on the parent)
The parent. You mean on the vmhost? Ours is VMware 5.5 U2, running on
HP hardware, so they aren't using Broadcom NICs..
