vCenter Server unresponsive

[toolmodel]

Hello all,

I am a high school student working on a test environment for my school. One of the big issues I have had with the vCenter servers that I have built is that they will go unresponsive at times for about a day and then suddenly work again. The reason that this really confounds me is that when it is unresposive (I can not ping it nor connect using vSphere Client) I can still connect to it fine using remote desktop. All of these servers are on fresh installations of Windows Server 2008 R2 with nothing else on them, there are no additional security features enabled. Neither rebooting the vm or the host fix the problem. Any ideas on how to solve this issue?

is there anything in the Windows Event Logs that may help pinpoint the problem? Is your DB instance local or remote?

Immediately following the restart of the service, the VCenter doesn't respond for some time.. the service starts, but it takes time for it finish loading the data and make it available

Turn off firewall and also any power features (like display after 20 minutes, or power down hard drive)
