We have a newly deployed SCCM 2012 R2 running on Windows Server 2012 R2. The W2K12 runs as VM on ESX 5.1.
After setting up the environment we had some very odd issues with OS deployment. The Task Sequence keeps failing when processing SCCM client installation. The issue occurs when installing the ConfigMgr client package then it fails straight away telling us that “The hash value is not correct (Error: 80091007; Source; Windows)”.
It’s was very consistent and it happened every time. Redistribute the OS Image was successful but the installation still failed
We also ad a similar issue with Microsoft Lync 2013 on Windows 2012 which was loosing network connections. After some troubleshooting on both issues it seems like the E1000 adapter is not working properly with Windows 2012.
Change the E1000 NIC to a VMXNET3 NIC and the issue will be solved.
VMXNET 3: The VMXNET 3 adapter is the next generation of a paravirtualized NIC designed for performance, and is not related to VMXNET or VMXNET 2. It offers all the features available in VMXNET 2, and adds several new features like multiqueue support (also known as Receive Side Scaling in Windows), IPv6 offloads, and MSI/MSI-X interrupt delivery.
VMXNET 3 is supported only the following Microsoft Windows platforms:
Windows 7, XP, 2003, 2003 R2, 2008, 2008 R2, and Server 2012
