Configure Windows Firewall to Allow TCP and UDP Ports 88
To configure Windows Firewall and allow TCP and UDP ports 88, follow these steps:
1. Press the Windows key and type “Windows Firewall” in the search bar. Open the Windows Firewall with Advanced Security application.
2. In the left-hand panel, click on Inbound Rules.
3. Locate and select the rule named “Kerberos Key Distribution Center (TCP-In)”.
4. Right-click the rule and choose Properties.
5. In the Properties window, go to the Protocols and Ports tab.
6. Make sure the Specific local ports option is selected. Add “88” to the list of ports.
7. Click OK to save the changes.
8. Repeat steps 3-7 for the rule named “Kerberos Key Distribution Center (UDP-In)”.
By allowing TCP and UDP ports 88 through Windows Firewall, you ensure proper communication for services like Active Directory and Kerberos authentication. This helps protect your system from security threats and compromise attempts.
Utilize IPv4 for Network Communication
If your system has detected a possible attempt to compromise security, it’s crucial to take immediate action to protect your network and data. Here are some helpful steps to address this issue:
1. Verify the error message: Take note of the specific error message or any suspicious activity you have observed.
2. Check credentials: Ensure that all users’ credentials are secure and not compromised. If necessary, reset passwords and update account information in the Credential Manager.
3. Investigate DNS and DHCP: Review the DNS and DHCP server configurations to identify any misconfigurations or potential vulnerabilities. Consider running diagnostic tools or consulting with your network administrator for further assistance.
4. Update software and patches: Keep your operating system, applications, and security software up to date with the latest patches and updates. This helps protect against known vulnerabilities, including those associated with CVE 2021.
5. Scan for malware: Run a thorough scan using Microsoft Defender or other reputable antivirus software to detect and remove any malware or malicious programs.
Remember, maintaining a secure network environment involves proactive monitoring and regular security assessments. Consider implementing additional security measures such as privilege escalation controls and network segmentation to mitigate future risks.
Set DNS Addresses to Obtain Automatically
To set DNS addresses to obtain automatically, follow these steps:
1. Click the Start menu button and select Control Panel.
2. Go to Network and Internet, and then click Network and Sharing Center.
3. On the left-hand side, click Change adapter settings.
4. Right-click on the network connection you are using and select Properties.
5. In the Properties window, scroll down and double-click on Internet Protocol Version 4 (TCP/IPv4).
6. Select the option “Obtain DNS server address automatically.”
7. Click OK to save the changes.
By setting the DNS addresses to obtain automatically, your workstation will automatically receive the appropriate DNS settings from the DHCP server. This helps ensure that your network connection is secure and minimizes the risk of DNS issues compromising security.
If you continue to experience problems or suspect suspicious activity, consider using Microsoft Defender or other security measures to protect your computer and network. Stay vigilant and regularly update your systems to mitigate the risk of compromise.
