We installed a server well over a year ago and had no problems with it until we recently moved it to a different site.
The Server is a Dell PowerEdge R720, Windows Server 2012 R2 that runs Hyper-v With 2 VMs (Exchange Server and AD/File Server) which i shall refer to as the 'Host'
We use Veeam Backup from another server to backup the two VMs and ever since the move around 2 weeks ago we've only been able to get a solid backup with Veeam 2-3 times.
Upon looking into this a bit further i found that the Host could not be pinged by the Backup server, i then found that i could not access the host through regular RDP either. The only way to access the server was to remote on from one of the VMs.
Once on the server i found that the Host seemed to have no connection to the network and could not ping anything other than the two VMs that it hosts.
The thing that i'm finding a little odd is that the VMs and the entire network are having no issues at all. The only issue coming from this is that the Veeam server can not find the Host meaning that it can't perform the backups.
If the Host is rebooted it seems to fix the problem for a few days and then it will just randomly start happening again.
The server has 4 Network connections configured into a NIC team.
Has anyone experienced anything similar in the past? or can anyone think of anything that may help to resolve this?
Thanks in advanced,
