I’m on Google fiber and can't download the newest ISO. I get a msg that says some block of IPs is being blocked because they are not who they say they are. Likewise, I have no anonymizer running and my ip is my own on google fiber. error msg; message code 715-123130 and b64dd3c8-ed16-4d46-87ac-a871691f1c41.Solved678Views5likes9CommentsDid Microsoft make a mistake? WinServer 2022 Standard and up.
Microsoft removed functionality of Windows Deployment Service. I know their are ways to to get around this but they either are hackjobs or deploying your own windows with PE. as far as i know of writing this. I know I could go linux. they have a simple cd to follow. Or Mac has their own version for macs. but not microsoft. They THREW it away for some stupid reason. Do I really have to do a VM or worse ditch DNS & DHCP?27Views0likes0CommentsZero Trust DNS is Here: Elevating Enterprise Security on Windows 11
When attackers target an enterprise today, they rarely begin with a blunt smash-through-the-front-door intrusion. They begin quietly by resolving a domain. In most cases, modern malware, phishing kits, and human-operated ransomware operators rely on DNS as the entry point to discover infrastructure, beacon command-and-control, and exfiltrate data. Thus, it is becoming even more important to secure DNS to help protect against increasingly frequent, complex, and expensive cyberattacks. Enterprises have invested heavily in Protective DNS services with cutting-edge threat intelligence to identify and block malicious domains in real time but if an endpoint device can simply bypass them, the entire Zero Trust posture is weakened. Today, Microsoft is closing that gap. Introducing Zero Trust DNS (ZTDNS) We are excited to announce that Zero Trust DNS (ZTDNS) is now generally available on Windows 11 Enterprise and Windows 11 Education editions. ZTDNS is a new enterprise security feature in Windows that helps ensure DNS policy configured on the enterprise DNS server is enforced on the device. This is an important advancement for organizations working to enable that outbound connectivity on managed Windows devices aligns with enterprise authorization and policy. ZTDNS provides device-level enforcement of an enterprise’s DNS policy, in-box on Windows 11 helping ensure devices only communicate with destinations the organization intends. It doesn’t require installing and managing additional agents or maintaining a “best effort” block list on each endpoint device. With ZTDNS, the enterprise DNS resolver becomes the policy source of truth and Windows becomes the enforcement point. For more information, check out our documentation. This can be particularly useful for organizations in highly regulated industries, or where compliance with NIST standards is of paramount importance. Without ZTDNS, the system DNS client could be pointed to a network-provided malicious DNS server, which can resolve unapproved domains and return incorrect resolutions to redirect the system to attacker’s endpoint. If the malicious DNS server uses encrypted DNS, IT administrators won’t be able to analyze the DNS traffic to prevent or mitigate potential attacks. Applications can use their own DNS client to completely bypass system policies. Also, system remains vulnerable to in-network attackers. ZTDNS protects against these attack vectors by mandating the use of Windows DNS client and only sending encrypted DNS queries to the trusted DNS servers. Since ZTDNS blocks all outbound connections and local name resolution by default, the system is protected against in-network threats. Why is ZTDNS needed? In enterprise scenarios, DNS is no longer just a lookup mechanism but a policy decision point. However, without device-level enforcement, attackers can hijack device DNS to: Redirect DNS queries from the device to a malicious or compromised DNS server Use their own encrypted DNS client and bypass system DNS client Bypass DNS completely with direct IP connections In such cases, organizations lose the ability to control which network destinations the endpoint is allowed to reach even if a Protective DNS service is used. ZTDNS addresses this by only allowing outbound connections to IP addresses that were resolved by the trusted DNS server for a query issued by the Windows DNS client. More importantly, it achieves this without terminating end-to-end encryption. How does ZTDNS work? ZTDNS integrates the Windows DNS client with the Windows Filtering Platform to help enforce domain-name-based network lockdown using encrypted DNS. ZTDNS is off by default and can be configured on a Windows 11 device with an enterprise-approved DNS over HTTPS (DoH) or DNS over TLS (DoT) server. When enabled, ZTDNS blocks all outbound IP-based connections by default and only allows outbound connections to IP addresses resolved by the trusted DNS server or those added to the manual exception list by the IT administrator. It mandates the use of encrypted DNS (DoH or DoT) and only trusts the DNS resolutions initiated by the Windows DNS client and answered by the trusted DNS server to create outbound allow exceptions. This helps provide a strong, enforceable control that aligns with Zero Trust principles: all destinations are untrusted by default unless specifically permitted. In a nutshell, when configured and enabled, ZTDNS will have the following effects on your Windows 11 device: Encrypted DNS enforcement (DoH or DoT) Default deny for outbound IPv4 and IPv6 traffic Dynamic allow listing of IP addresses returned by trusted DNS servers Static allow listing of IP addresses approved by the IT administrator via manual exceptions Centralized logging of permitted and blocked connections Deploying ZTDNS ZTDNS is available in the latest builds of Windows 11 Enterprise and Windows 11 Education. To deploy ZTDNS, enterprises can configure and enable it via: netsh commands JSON configuration We are also actively developing a Microsoft Intune experience for ZTDNS and we will share more information when the details are available.

The scanner has stopped scanning to their server since I upgraded the server OS from Windows Server 2022 to 2025. • Installed the Ricoh drivers for both the scanner and printer (from Ricoh’s web site) • Created a new simple share/filepath for the scanner to send to (\\SERVER2022\Scans) • Used IP address (10.1.10.2) instead of server name in file (UNC) path • Entered admin credentials with or without server name (it is a workgroup server, not a DC) • Created another user and tried all above with that new admin • With either server share and/or user, tried different permissions on the shared folder • Tried disabling/enabling inherited permissions on the shared folder • Disabled the Advanced Firewall entirely for testing – no change either way • Double checked incoming ports/programs on the firewall – all required were open • Activated SMB1 on server, tried with or without SMB2/SMB3 disabled • I was able to create a share on two other computers; one running Windows 10 and one running Windows 11. They both worked.67Views0likes0CommentsNPS network policy with multiple Client ip4 addesses
I have a wireless policy on my NPS server with the primary wireless controller added using a Client IPv4 address entry in the policy. I want to add the backup controller as well but it seems it is adding it as a and condition. I need it to be added as an or condition when the primary controller is unreachable. How can I add multiple Client ip4 addessess in a Network policy with an or condition? An and condition would require both to be reachable. thanks.50Views0likes0CommentsAllow VMs attached to internal switch on hyper-V win2k19 access Internet
Hi, I have 4 VMs attached to an internal switch with IPs 10.10.0.*, assigned 10.10.0.1 to the switch. One of the NICs on the host has the 192.168.1.70 which I shared its connection with the internal switch but I am not able to browse internet from the VMs. What can be missing?

I have Created an internal switch and attached it to 4 VMs (for a lab setup) on a win2k19 hyper-V host. The hyper-V is in the my local home subnet 192.168.0.1. The 4 VMs are configured with following IPs and gateway. VM1 10.10.0.10 -DefaultGateway 10.10.0.1 VM2 10.10.0.11 -DefaultGateway 10.10.0.1 VM3 10.10.0.12 -DefaultGateway 10.10.0.1 VM4 10.10.0.13 -DefaultGateway 10.10.0.1 In the lab document, it is not indicated how/where to assign the 10.10.0..1 IP? When I check the vEthernet (Private Network), It has "DHCP" for IP and got my local DNS IP. Checking its status, I see DHCP Enabled: Yes Autoconfiguration IPv4 Address: 169.254.32.39 IPv4 Subnet Mask: 255.255.0.0 IPv4 Default Gateway: Not sure where this 169.254.... IP comes from? I tried assigning the IP 10.10.0.1 to this but it fails. In fact I need to allow VMs to access some host folders as well as internet to download some Microsoft tools.
