Today, I helped a client migrate Exchange from 2010 to 2019. As you know, Exchange 2010 can’t migrate to 2019 directly. You need to migrate Exchange from 2010 to 2016 and then 2019.
When I tried to prepare the AD schema for installing Exchange 2016 CU23, and it happened the error message is below.
“One or more servers in the existing organization are running Exchange 2000 Server or Exchange Server 2003”.
The error is because they were not uninstalled Exchange 2000 or 2003 completed. Let’s fix it.
Veeam released Veeam Backup for Microsoft 365 v6 on March 9, 2022, there are lots of new features at this version included Self-Service Restore Portal, Backup copy to low-cost object storage… etc. the detail information as following link.
Cyberattack is one of the fastest growing crimes in the world, we have seen passwords being leaked regularly, local administrator account is like God of machine, it has superpower to do anything for the machine. A lot of IT guys simply use the same password for all local administrator accounts, the attacker easy access to the whole estate if one machine is breached.
Microsoft LAPS is one of solutions to prevent the issues, The “Local Administrator Password Solution” (LAPS) provides management of local account passwords of domain joined computers. Passwords are stored in Active Directory (AD) and protected by ACL, so only eligible users can read it or request its reset. Today, I am going to show you how to deploy it.
If you tried to restore VMs (or physical machines) and it shows the trust relationship between this workstation and the primary domain failed, I won’t recommend using rejoin domain to solve issues, because it will happen unexpected issues after disjoin and rejoin domain.
Today, I am going to show you how to fix it without disjoin and rejoin domain.
Today, we help our client to build a new S2D server as new Veeam Repository, now, we need to move the SOBR performance tier from the old repository server to this new server, I am going to show you how to move it.
Did you try to use Veeam Agent for Windows feature to backup physical machines? Have you been noticed the exiting backups with a warning “Collecting recovery media files Details: Windows recovery image file not found”? Today, I am going to show you how to fix the issues.
Microsoft released Cumulative Update 18 for Microsoft Exchange Server 2016 on September 15, 2020. This cumulative update includes fixes for nonsecurity issues and all previously released fixes for security and nonsecurity issues. These fixes will also be included in later cumulative updates for Exchange Server 2016. This update also resolves a vulnerability, see Microsoft Common Vulnerabilities and Exposures CVE-2020-16875.
When you try to activate Windows server 2019 from evaluation version, do you always get an error message “the product key you entered didn’t work. Check the product key and try again, or enter a different one. (0x80070490)”?
Today, I am going to show you how to install license key to activate Windows Server 2019 from Evaluation version. Let’s follow steps to activate your windows server 2019 (it also can be use for activating Windows Server 2016).
Note: you cannot use slmgr /ipk command with VLSC MAK key or Retail to activate evaluation edition server directly.
Have you been followed my previously blog to build up Hyper-V nested virtual machine on Microsoft Azure? If you don’t, you better build it right now, because this is pre-requisites and you will get lots of benefit for your lab or even production environment, you can reference this link and build it. If you did, congratulation! You can create a nested gest virtual machine and install Firewall (e.g. Sophos XG, Fortinet…) for free, why we still need to build firewall at our Azure Hyper-V nested environment? Because it supports lots functions that we cannot get the functions for free from Azure, e.g. server load balance, firewall, SNAT, application filter, IPS…and so on, we also can use it for LAB or simulate issues or POC. I am going to show how to build Sophos XG here.
As we know, you can easy to create VMs, Firewalls, Load Balancers on Microsoft Azure, you also can make routing path change but all of them will cost you lots of money, it depends on how many virtual devices or virtual machines that you created.
Today, I am going to show you how to build Hyper-V nested VM with multiple public IP address, you just need to pay Microsoft for one Hyper-V host with storage space and public IP addresses, you can install firewall, created lots of VMs, load balancer, control routing path, port forwarding and so on, we can use them for LAB test, POC, or even production.
