Is NTLM Installed by Default in Server 2019?
In the realm of server operating systems, Windows Server 2019 stands out as a robust and versatile platform for businesses of all sizes. One of the key security protocols that comes with this server operating system is the NT LAN Manager (NTLM). But is NTLM installed by default in Server 2019? Let’s delve into this question and explore the role of NTLM in the Windows Server 2019 ecosystem.
Understanding NTLM
NTLM is a Microsoft authentication protocol that was introduced in the early 1990s. It is designed to provide authentication services for client-server applications running over the network. The protocol is based on a challenge-response mechanism, where the client proves its identity by responding to a challenge from the server.
Is NTLM Installed by Default in Server 2019?
Yes, NTLM is indeed installed by default in Windows Server 2019. This means that if you have a fresh installation of Server 2019, you will find NTLM already configured on your system. However, it is important to note that while NTLM is installed by default, it is not always enabled.
Enabling and Disabling NTLM in Server 2019
The enablement or disablement of NTLM in Server 2019 depends on the specific requirements of your network environment. In some cases, you may want to disable NTLM for security reasons, while in others, you may need to enable it to ensure compatibility with legacy applications.
To enable or disable NTLM in Server 2019, you can use the Group Policy Editor. Here’s how you can do it:
1. Open the Group Policy Editor by typing “gpedit.msc” in the Run dialog box.
2. Navigate to “Computer Configuration” > “Windows Settings” > “Security Settings” > “Local Policies” > “Security Options.”
3. Look for the policy “Network security: LAN Manager authentication level” and double-click on it.
4. You will see three options: “Send LM & NTLMv2 responses,” “Send LM & NTLM responses,” and “Use NTLMv2 session security if negotiated.”
5. To enable NTLM, select “Send LM & NTLMv2 responses.” To disable it, select “Send LM & NTLM responses.”
Considerations for NTLM in Server 2019
While NTLM is installed by default in Server 2019, it is essential to understand the implications of using this protocol. NTLM has been criticized for its security vulnerabilities, particularly in the wake of the WannaCry ransomware attack. As a result, it is recommended to use more secure authentication protocols like Kerberos and NTLMv2.
Moreover, disabling NTLM may impact the compatibility of certain legacy applications that rely on this protocol. In such cases, it is crucial to evaluate the risks and benefits before making a decision.
In conclusion, NTLM is installed by default in Windows Server 2019, but its enablement or disablement depends on your network environment and security requirements. By understanding the role of NTLM and its implications, you can make informed decisions to ensure the security and compatibility of your server infrastructure.
