ESXi Host keeps disconnecting from vCenter

Faced an issue where in a ESXi host keep disconnecting form the vCenter
When we reconnect , it does connect back however loses connectivity again after few minutes

Although we could still ping and connect (RDP) to the VM's on the host.

It felt somehow the heartbeats form the host to vCenter were lost as the Host was behind the firewall

We needed to enable UDP/902 between the host and vCenter to get the issue fixed

Hope this help

Group Policy Object did not apply because it failed with error code '0x80070534 No mapping between account names and security IDs was done

One of our servers was losing the Local Admin settings as we control them using GPO (restricted Groups) We were receiving the following event on this particular server : Event ID 4098 Application Event Log The computer 'Administrators (built-in)' preference item in the 'Servers Local Admins {odjd9DBD-22AF-48EA-ADF5-F42ADE4182hst}' Group Policy Object did not apply because it failed with error code '0x80070534 No mapping between account names and security IDs was done.' This error was suppressed. To fix the issue we deleted all the folders from the following location and rebooted the server C:\ProgramData\Microsoft\Group Policy\History Hope this helps.

iDRAC 7 Shows no Signal in Virtual Console Preview

Recently i logged on to iDRAC for one of our Dell R720 servers,however somehow the console redirection did not work at all. I kept on seeing No Signal on the Virtual console Preview. I tried Rebooting the server but that did not help. Finally i clicked on Reset iDRAC and this did the trick. It may take around 2 -5 minutes before you can access iDRAC page again. I had to power on the server through iDRAC before anything showed up on console. Hope this Helps.
