FYI, this isn't entirely related since I'm dealing with a different network card, but the 2013.09 SPP that came out the other day has updated NIC drivers for the NC382i on my DL360 G7 servers (and many other models... it's the "HP Broadcom 1Gb Multifunction Driver) for Win64.
It's version 7.8.6.0 and it does something very strange... we're running Server 2012 with Hyper-V, and after installing this NIC driver, our virtual machines running on this box (2 different servers in fact, have the same issue) are having problems.
The network connection between the virtuals and any other system are sporadic. I haven't taken the time to track it specifically to see if it's just dropping packets or what.
For instance, we have a virtualized Ubuntu 13.04 server running Couchbase. Attempts to connect to the default port 8091 that Couchbase uses are useless, it just times out. But if I connect from another virtual machine on the same physical host, it's okay. It's only when it goes on the actual network that it freaks out.
It may be all communications on the server, even to the host OS, but a lot of things like RDP sessions are pretty tolerant of network issues.
The solution for me was rolling back to the previous drivers, version 7.4.14.0. That's all it took, and all of a sudden, all the software running on those virtual machines like Couchbase, MSSQL, IIS, etc. started working just fine.
I'm glad this was on our test environment... if I hadn't caught that before deploying to our production servers, it would have been a very bad day. It was bad enough as it is, dealing with developers and QA who couldn't do their work for most of a morning.
