Hands On with Microsoft Dynamics GP October 2019 Release: Microsoft Dynamics GP client prerequisites

Microsoft Dynamics GPThis post is part of the series where I am going hands on with the new version of Microsoft Dynamics GP.

Before installing any of the Microsoft Dynamics GP components, you need to make sure the system requirements are met. On top of this there is also some prerequisites which need to be met before the Microsoft Dynamics GP client or other components can be installed.

Most of these prerequisites can be handled by installer process, there is one which cannot; this is the .NET Framework 3.5 feature which is installed using the Add Roles and Features Wizard available via Server Manager on Windows Server or using Turn Windows features on or off accessible via Program and Features on Windows.

If the PC or server you’re planning to install Microsoft Dynamics GP onto has an Internet connection, then the .NET can be installed simply by using the wizard. However, if, for whatever reason, you don’t have an Internet connection available, the install process isn’t quite that smooth.

However, for both server and PC you can do an offline install and I have blogged about this several years ago:

The above articles are for older versions of Windows Server and Windows, but the process is exactly the same on current versions.

An authentication error has occurred; this could be due to CredSSP encryption oracle remediation

Windows ServerThis error first came up early in 2018, but I’ve stumbled across it a couple of times recently and had to hunt around for the solution, so I am posting it here so I know where to find it next time.

Microsoft released an update to address vulnerabilities for the Credential Security Support Provider protocol (CredSSP) used by Remote Desktop Protocol (RDP) connections for Windows clients and Windows Server.

Since that hotfix came out, if you try to connect from a patched machine to an unpatched one, you receive this error:

CredSSP error

Remote Desktop Protocol

An authentication error has occurred.
The function requested is not supported.

Remote computer: {server name}
This could be due to CredSSP encryption oracle remediation.

Enable Bitlocker on Removable Drive

WindowsWhen I joined ISC Software I was given a new laptop and associated peripherals which included a removable 1TB SSD. As this SSD travels with me, one of the first things I did was encrypt it with BitLocker.

To encrypt a drive with BitLocker, launch Windows Explorer, right click on the drive and select Turn BitLocker On. When the BitLocker Drive Encryption window appears, click Encrypt this drive using BitLocker Drive Encryption:

Disable IE Enhanced Security Configuration

Windows ServerI do a lot of work in virtual machines and this work often involves using the web browser; this is usually just for web client, SSRS or other similar local pages, but even then Internet Explorer Enhanced Security Configuration will get in the way and need to be disabled.

I never remember where the setting for this is, so I am posting here to make it easy to find in future. To change the setting, open Server Manager; in the left pane, click Local Server:

Server Manager > Dashboard

In the main section of the page, click the word ON next to IE Enhanced Security Configuration:

PowerShell to Promote Domain Controller

Windows ServerWhen testing Microsoft Dynamics GP, I often need a domain controller within my set of virtual machines. I’ve been promoting a server to be a domain controller manually, but it recently occurred to me that I could probably do the same task using PowerShell.

After doing some research, I came up with four commands which will rename and restart the server, install the Active Directory feature and add a forest.

To rename a server, run the following command, replacing the highligted section with the new server name:

Rename-computer -newname {server name}
