Usually I tend to use the iPhone WiFi hotspot feature. But lately, I had to switch to USB tethering, because I had to work a whole workday using the hotspot feature. USB tethering saves battery and the connection was more reliable for me. Please note, that you need to install iTunes to use USB tethering, because the necessary Ethernet driver is only available with iTunes. Without this driver, Windows won’t recorgnize the iPhone as an Ethernet connection.
One of my customers replaced the old Veeam environment with new gear. The HW was pretty simple designed: two HPE ProLiant per server two HPE D3610 enclosures with 6 TB disks ~ 5km between backup server and backup copy destination One server was designed to act as the Veeam backup server and repository, and the second server was designed to act as the backup copy destination. Both servers were running Windows Server 2019 Standard.
Using physical clients as Horizon View agents is pretty common for me. My office pc, as well as my Lenovo X250 are often used by using the Horizon View Client and the Blast protocol. But as good as the performance is, there were a couple of things that bugged me. On my office pc, I encountered pretty often a black screen, either on first connect, or on reconnect. The typical issue caused by misconfigured firewall policies, but this was completly out of scope in this case, because my collegues never had issues with black screens.
One of my customers purchased a bunch of Microsoft 365 subscriptions in order to use them with Office 365 and Windows 10 Enterprise. The customer called me because he had trouble to activate the Windows 10 Enterprise license. Source: Microsoft/ microsoft.com I would like so summarize some of the requirements in order to successfuly active Windows 10 Enterprise subscriptions. License First of all, there is a licensing requirement. You need at least a Windows 10 Pro or Windows 10 Pro Education.
You might got this news some days ago: Starting with September 1, 2020, browsers and devices from Apple, Google, and Mozilla will show errors for new TLS certificates that have a lifespan greater than 398 days. Due to this move from Apple, Google and Mozilla, you have to deal with the replacement of certificates much more often. And we all know: Replacing certificates can be a real PITA! Replacing TLS certificates used for ADFS and Office 365 can be a challenging task, and this blog post will cover the neccessary steps.
THIS IS FIXED in ESXi 6.5 U3 and 6.7 U3. See KB67426 (Performance issues with Windows 10 version 1809 VMs running on snapshots) for more information. TL;DR: This bug is still up to date and has not been fixed yet! Some user in the VMTN thread mentioned a hotpatch from VMware, which seems to be pulled. A fix for this issue will be available with ESXi 6.5 U3 and 6.7 U3.
Yesterday, I got one of these mails from a customer that make you think “Ehm, no”. Can you please enable the TPM on all VMs. The customer The short answer is “Ehm, no!”. But I’m a kind guy, so I added some explanation to my answer. Let’s add some context around this topic. The Trusted Platform Module (TPM) is a cryptoprocessor that offers various functions. For example, BitLocker uses the TPM to protect encryption keys.
Implementing a public key infrastructure (PKI) is a recurring task for me. More and more customers tend to implement a PKI in their environment. Mostly not to increase security, rather then to get rid of browser warnings because of self-signed certificates, to secure intra-org email communication with S/MIME, or to sign Microsoft Office macros. What is a 2-tier PKI? Why is a multi-tier PKI hierarchy a good idea? Such a hierarchy typically consits of a root Certificate Authority (CA), and an issuing CA.
Today, a customer called me and reported, on the first sight, a pretty weired error: Only Windows clients were unable to login into a WPA2-Enterprise wireless network. The setup itself was pretty simple: Cisco Meraki WiFi access points, a Windows Network Protection Server (NPS) on a Windows Server 2016 Domain Controller, and a Sophos SG 125 was acting as DHCP for different WiFi networks. Windows clients failed to authenticate, but Apple iOS, Android, and even Windows 10 Tablets had no problem.
As part of a maintenance job I had to update a 2-node Exchange Database Availability Group and a file-share witness server. After the installation of Windows updates on the witness server and the obligatory reboot, the witness left in a failed state. [PS] C:\Windows\system32>Get-DatabaseAvailabilityGroup -Identity DAG1 -Status | fl *wit* WARNING: Database availability group ‘DAG01’ witness is in a failed state. The database availability group requires the witness server to maintain quorum.
