NameSpace ‘Microsoft.Policies.WindowsStore’ Error
Microsoft.Policies.WindowsStore KB ID 0001817 Problem While working in the Group Policy Management tool, upon expanding administrative templates I got this error.

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...
Exchange 2019 Migration from Exchange 2016
KB ID 0001472 Exchange 2019 Migration If Exchange 2016 was Exchange 2013 in a pretty dress, then with Exchange 2019 it’s simply added a hat. In the past, every third Exchange release was a major rebuild, but Exchange 2016 is simply Exchange version 15.1 (Exchange 2013 was 15.0 and Exchange 2016 is version 15.1). So the Exchange 2019 Migration is pretty much the same as it was from 2013 > 2016, or even 2016 > 2016. There...

Microsoft Edge on Server 2019/2016 (and Citrix)
KB ID 0001657 Problem In a fit of lunacy Microsoft have called ‘their’ new browser Microsoft Edge, so we can spend the next few months confusing it with Edge. Plus every Google search for GPO settings, error messages etc will all now show search results for the old Edge Browser not the new Microsoft Edge browser! Perhaps the same doofus at Microsoft who called the Exchange sync Active Sync when Microsoft already had a...
In Place Upgrade Windows 2016 to Windows 2019
KB ID 0001761 Problem For the last twenty years or so I’ve said “In place upgrades are a bad idea”, my rationale has been that if something is broken we are simply migrating that problem, and we are relying on a lot of factors, (some of which may be unknown.) That we will just have to ‘trust that it will work’. Most modern servers are virtual so we can snapshot them, or clone them and test the upgrade...
