Windows: Migrate DHCP HA
Migrate DHCP HA KB ID 0001826 Problem I got an email last week. “Hi thanks for your video. I have two win 2012 DC DHCP on a failover/load balance config and want to migrate to new Win 2022 VMs. What’s the exact procedure? If it’s a single VM it’s easy but I’m not sure about if it’s on a failover setup.” Well migrating the domain controller element I’ve covered before. Migrate From Server...
Deny RDS
Deny RDS KB ID 0001825 Problem Way back when I started doing tech (in the days of Novell 4 and NT4), my mantra was, if you must deny something then you’ve done something wrong. Now I work for a UK based MSP that offers SPLA licensing to clients. Unlike typical RDS licensing, With SPLA this requires every ‘capable’ AD user that ‘can’ RDP onto a server (regardless of it’s a Session Host RDS Server or...

In that time, you’ve probably had to copy ADMX (and ADML) files into your central store manually.

Solution: Microsoft.Policies.WindowsStore Error This is because in your policy definitions there are two (four actually) files that are pointing...
Disable LLMNR and NetBIOS (via GPO)
Disable LLMNR and NetBIOS KB ID 0001816 Problem LLMNR is a protocol that’s used both in IPv4 and IPv6 networks to provide name resolution (in the absense of DNS), the problem with it is that it is wide open to exploitation and can be used to perform a MITM attack on your network. NetBIOS is much older and asscociated with IPv4 networks only. Really old Microsoft OSs used to rely on it heavily, but these days its pretty much...
