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? Thanks11Views0likes0CommentsAllow VMS on hyper-V host on win2k19 attached to internal network interface
Hi, how can allow VMs accssinternet on host Hyper-V on 2019? I have hyper-v on 192.168.0.* and my 4 VMs are 10.10.0.*. I assigned 10.10.0.1 to the virtual switch, on VMs I assigned default gateway to this switch13Views0likes0CommentsAllow Hyper-V VM attached to Internal Switch access internet and host folders
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.

A contractor has asserted that latency delays are caused by a "misconfiguration" of the hardware of certain machines that produces flooding of the network with bad packets. They have asserted that they find this when checking out a new site. Is this also associated with a Quality of Service setting on a site's server if it would then release such large number of packets to the network? Does this also require careful adjustment of the MTU (Max. Trans. Unit) settings on each base server? (MS Server setting???) Or does the server simply transmit all the packets it receives from networked machines?48Views0likes0CommentsUntagged VLAN - Server 2025 Hyper-V
Hi, I have a strage issue and not finding a solution. Using Server 2025 with two node Hyper-V cluster. Most of the machines using VLANs which works fine. Some machines using no VLAN config. Which usually means the "Access VLAN 1" regarding our switch configuration. With Server 2019 this worked fine. With Server 2025 same NIC port, same server/NIC hardware "Untagged" VMs don't get any network connection. If I add a second NIC to the VM "Untagged" the NIC get immidiatly an IP address and has a proper connection. If I remove the first NIC, the second NIC stop working. It looks like something has changed with Server 2025 (maybe already with Server 2022). Do you have any idea what kinde of problem I have found? Thanks Jack618Views0likes4CommentsDeploying Multiple NPS Servers
I have been working on ditching our password-based WiFi with WPA2-Enterprise. On DC1 I deployed internal CA, NPS, and group policies that auto-request certs and deploy wireless network settings. Cisco AP is pointed to DC1 as the radius server. NPS has been registered in AD and wireless network policy has been created. Test laptops get their cert and connect just fine. It's working. For redundancy, I installed NPS on DC2. This NPS instance has also been registered in AD, and I imported the NPS config from DC1 to DC2 NPS. Cisco AP has DC1 as first radius server and DC2 as second radius server. If I stop NPS on DC1 to force the Cisco AP to authenticate against DC2, test laptops won't authenticate and connect. What am I missing? They're configured exactly the same (except DC1 hosts the CA...I was under the assumption the CA is AD integrated).166Views0likes2CommentsAdvice for replacing a Windows 2012R2 file server
We have a small company network that includes one Windows Server 2012R2 file server necessary to run Sequel for two server hosted business applications, file and print services for the user accounts and is also the Domain Controller for the Active Directory local forest and domain. Six Windows 11 Pro workstations are domain attached to the file server. The workstations all have a local user account and after domain attaching to the file server, a user.Acme user account with Administrator rights to their local computer. Each has its own 192.168.1.x static address and uses their domain user account with mapped drives to access the fileserver. The existing file server name is ACMEWS2012R2, local public static ip 192.168.1.12, DNS Domain Acme.LAN, Netbios name ACME, local accounts are located in \Users\username, and runs SQL Server Express 2012 with default MSSQL database name and mixed security using the SA with password credentials. The new file server will be using Windows Server 2022 (the company apps are not yet certified for 2025) and SQL SVR Express 2022 and I am looking for information about what configuration decisions I can make to hopefully minimize the need to install new user accounts on the workstations, copy all the user folders between users accounts and reinstall applications. My understanding of Domain security is limited, knowing just enough to get workstations attached and properly accessing the file server SQL based applications. My Google results have provided some piecemeal answers, but I would like to better understand the big picture before starting the server upgrade and make some irreversible configuration choices that would cause unnecessary work re-attaching the workstations. I would first ask for recommendations whether and why to keep or change each of the following: The file server machine name The file server 192.168.1.12 IP address The file server Administrator account and password. The Acme.LAN forest and root domain name that was defined after adding the Active Directory Domain Service role that also added File and Print Services and Group Policy Management. The SQL Server Express default MSSQL database name The SQL Server Express SA account name and password I would also ask about the best steps for disconnecting workstations from the old domain then joining the new domain to hopefully retain the existing workstation user account, or if not, to minimize the need to copy users folders between the user accounts and / or uninstall then reinstall the workstation applications to properly authenticate to the new user account. I would greatly appreciate some experienced insights for how to best accomplish these upgrade goals. Thanks, all!26Views0likes0CommentsWindows Server 2016 and internet issues
Hello everyone, I'm relatively new here and hoping for some help. I'm IT at a school in Manhattan that has an old Dell tower running Windows Server 2016 in the basement that is not in use any more with the school as they have transferred over everything to digital. This was set up before my time working here and the person who set it up unfortunately did not leave any notes. We are ready to disconnect the machine as all of it's functions have been moved elsewhere. But, every time it is turned off or disconnected from our network patch, the internet in the entire building goes dead. I do not have previous experience with these kinds of servers and am trying to figure out what could possibly be causing this. I am concerned because the machine is old and feels like it's being held together by duct tape, and if it goes down, I hoping internet doesn't go with it. Looking for any advice or knowledge about these servers and what I can try to do to disconnect it.219Views0likes4CommentsAllow to take RDP from Laptop only and not from IP
