Unfortunately for […]

RHEL 8 and the VMware customization hell

/by

Normally VMware customization works pretty good. That is due to the fact that most of us only deploy or need to customize Windows servers and desktops. It kicks off sysprep, sets some predefined settings and you’re good to go. But now we’re talking about customizing Linux and there has been some changes over the years […]

No output when using multiple COM-object requests within PowerShell

/by

When trying to get information from a webpage, the invoke-webrequest isn’t always sufficient. Especially when the webpage uses Ajax or other fancy javascript frameworks. If this is the case, you most likely will be using a .NET com object to get the requested information of a webpage. With such a com object you can open […]

When using a vRealize Automation appliance with integrated vRealize Orchestrator, it can sometimes happen that the orchestrator is not responding well to the automation server.

Change DNS server on vLCM Appliance

Changing the DNS configuration under Windows is […]

VRA remove waiting on retry status
