If you use VAAI-compatible storage and provision VMs thinly, you need to perform a space reclaim from time to time to be able to use the deleted VMFS blocks again. In the VMware Knowledge Base the procedure is described using "esxcli", I find the ... Read more

The website helps ... Read more
Microsoft has released its new tool "Advanced Threat Analytics" (ATA). Reason enough to try out the new tool. ATA can be downloaded here in a 90-day demo: https://technet.microsoft.com/de-de/evalcenter/mt228154 By the way, there is also a key in the MSDN subscription: I am testing the whole thing in my Hyper-V playground. The ATA VM requires 2 network cards, and ... Read more

If the F5 iApp is used for VMware View and extended accordingly for 2-factor authentication, a "User name or password incorrect" message appears between the two queries. This is a bug that is caused by the F5 ... Read more
How SPF works SPF (Sender Policy Framework) is a simple method for identifying forged senders and blocking them as SPAM.
