Hi,<br />
<br />
We have a customer that use Windows 2008 R2 with Hyper-V to run three machines.<br />
<br />
Those three machines was P2V couple of months ago and working fine since then.<br />
In the last couple of days one of the machines (Windows 2003 32 bit SP2) start lost the connectivity randomly from the network.<br />
<br />
The connectivity from the machine to the network working fine and the hyper-v machine connectivity is also working fine, the only problem is from the network to that machine.<br />
<br />
We must say that all other machines continue to work without any problem.<br />
<br />
Just for your information, all the latest drivers and updates installed for hyper-v and the VM machine, antivirus is ESET.<br />
<br />
We check some forums and try to find any solution, but we didn't find nothing that is relevant to this problem.<br />

Do someone have a clue what to do?

Hi,

We have a customer that use Windows 2008 R2 with Hyper-V to run three machines.

Those three machines was P2V couple of months ago and working fine since then.
In the last couple of days one of the machines (Windows 2003 32 bit SP2) start lost the connectivity randomly from the network.

The connectivity from the machine to the network working fine and the hyper-v machine connectivity is also working fine, the only problem is from the network to that machine.

We must say that all other machines continue to work without any problem.

Just for your information, all the latest drivers and updates installed for hyper-v and the VM machine, antivirus is ESET.

Windows 2003 Server that running on Windows 2008 R2 Hyper-v lost network packets

Microsoft Virtual Server was a virtualization solution that facilitated the creation of virtual machines on the Windows XP, Windows Vista and Windows Server 2003 operating systems. Virtual machines are created and managed through a web-based interface that relies on Internet Information Services (IIS) or through a Windows client application tool called VMRCplus. Features included Linux guest operating system support, Virtual Disk Precompactor, symmetric multiprocessing (SMP), x64 host operating system support, the ability to mount virtual hard drives on the host machine and additional operating systems support, including Windows Vista, and a volume shadow copy writer.

Microsoft Virtual Server

This topic area includes legacy versions of Windows prior to Windows 2000: Windows 3/3.1, Windows 95 and Windows 98, plus any other Windows-related versions including Windows Mobile.

Windows OS

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.
