A few notes from myself, as I was asked multiple time during the last few weeks about the option and how it will be implemented into the HTML5 client. As… Continue reading VMware Tools and VM Hardware Update in vSphere 6.7U1
I won't forget to double, double, double check a local NTP service ever again. Everyone knows, if something does not work, it's DNS. I agree. But almost as important as the reverse/forward DNS lookup is the correct time given by a local NTP service. I learned it the really hard way and will probably tell… Continue reading Check the time. Like… really! Check it! VMware PSC queries Windows Server NTP Service
Earlier this month I started a Twitter poll and asked the community if anyone would be interested in some kind of community gathering besides the VMUG or any other event. I thought about this because, looking at the western of Germany, there seems to be a huge gap with a lot of potential. There are… Continue reading Havin’ a vBeer? Western Germany Meet-Up

Another situation I was facing two weeks ago while upgrading two Windows vCenter Server 5.5 including vSphere Replication Appliances to the latest vCenter Server Appliance 6.5U1. As the upgrade process is fairly known by now, I was sure I will need to reset the firstname.lastname@example.org password due the expiration settings. But I also needed to… Continue reading [INFO] Changing the default SSL password during the vCenter Server certification renewal
I was talking to a friend of mine earlier this week about a situation regarding a newly installed VMware vCenter Server Appliance 6.5U1 and was looking for an explanation, which is why this blog post is created. It's just an information about my findings. I was setting up a new vCSA 6.5U1 recently and discovered… Continue reading [INFO] vCSA 6.5U1 timesyncd fallback servers
