I have come across an odd one... I just rebuilt a Dell R710 with 4 Onboard Broadcom NICs and BIOS NON - UFEI Boot Mode.
I installed Windows 2012 R2 Standard GUI. No matter what types of configurations I have tried...I can not ping anything on the network other than the gateway. I have turned off the firewall, I have disabled all but the primary NIC. I have turned off the software firewall. I can' reach other servers on the network by \\hostname but not via IP Address ping. There is no ICMP restrictions in place. This is obviously causing issues reaching the soon to be retired Windows 2008 Server + Hyper-V that the host is actually Running Exchange 2003 (Yes this was supported but lots of problems so we are planning on building two guests on the new R710 for Exchange)
That part that has me stumped is if I rebuild the R710 in UFEI mode, the networking issue is no longer there, but instead VGA output can ever go beyond 640x480 no matter what driver/firmware edits are done. So UFEI resolves networking issue, gives me unusable and unchangeable video output. BIOS boot gives me functional video and unstable unusable networking :(
I have tried patched and unpatched OS, I have applied current firmware updates and all driver files are current. In 25+ years, I can say I am really stumped on this one! A simple rebuild has turned into a monster hair pulling nightmare.
Any ideas?
Thanks in advance :)
