Is it possible to force DNS settings to update on a Windows 7 client with DHCP from the server? - dns

Is there a command line or gui tool that I can use to make a client update its local nic settings without making them reboot or ipconfig /renew? I changed the DNS settings but the computers that have already received their IP address via dhcp need the new dns settings.

If you want to update the DNS settings and keep the clients as "auto obtain DNS settings from DHCP", then the answer is NO. However, you can set the DNS setting remotely using the netsh command line. Please note when you set the DNS using that command, you statically change the client's network properties.

Get WSL2 DNS to use Hosts DNS from DHCP

I'm trying to use WSL2 but the DNS isn't working, nothing resolves. I've seen lots of articles about disabling resolv.conf generation and putting in a manual entry, however this won't work for me. My workplace block the port DNS uses so I can't use 1.1.1.1 etc and I can't use the corporate DNS server IP as I want a solution that will work when I go home as well.
Is there a way for WSL2 to be able to use the DNS settings provided by the Hosts DHCP lease? I've tried to change the virtual switch (WSL) in the Virtual Switch Manager to be External but it's still picking up an IP from the DHCP server.
Am I missing some Windows configuration or do I need some Linux Fu to change the config. I was trying to get Podman-Desktop running and couldn't pull any images at work which is what started this off.

Mimic FQDN on a home machine not on a domain

I have a home PC running Windows 10, no domain controller, and therefore by default I do not have a FQDN for the machine.
I am trying to setup some server software for testing purposes, and it requires that I use a FQDN.
How can I manipulate my hosts file to mimic a FQDN?
Extra info, please let me know in comments if you need more.
There will be no other machines trying to access this other than the machine I am running the software on (my home PC)
I also think that my IP address is not static.
I believe you can just add a host entry corresponding to the IP address of your machine to all machines that need to address it using its FQDN. The hosts file can be found in System32\Drivers\etc. Just add an entry with your IP and the host to it, for example 192.168.0.1 mymachine.local.
Another option would be setting up your own DNS server which is relatively harder. The biggest problem is presented by you not having a static IP address, you should either set a static IP or configure your DHCP server to reserve an IP for you based on your adapter's MAC address.

How to set a new IP address for a clone Linux machine under VMware

I have cloned a Linux box under VMWare and I would like to use this clone server as a dev server. The clone server is turned off as its IT address will conflict with my production server. I have tried to change its IP address by going to Edit VM setting using VMware workstation but I could not see any option to change IP address. I could only see and generate a new MAC address.
I have also used Vsphere Web client and look for an option to set the IP address but could not see any option.
I guess the only option I have to to shut down my production server, turn on my dev server, change its IP address and then turn on my production server.
Is there any other way to achieve this?
Thanks

Internet not working without preferred DNS server

My machine is connected to the office net work using wifi. My internet was working for some time without any issue. Suddenly this morning the internet stopped working although I could ping to 8.8.8.8 and other network IPs. I set the preferred DNS server and the alternate DNS server and made it work again. My question is why was it working without these settings and why did I need to enter these settings suddenly? What changes did my computer go through without me doing anything?
Had the DNS on your machine been set before? If so,minor changes to a WIFI policy would then make your machine create a second WIFI network connection. This would then make your previously set DNS no longer valid.

How do you set up a perforce server to work over the internet?

I was setting up a Perforce server and only noticed options for localhosts and such. What I'm trying to do is setup up the server on a desktop machine at one household, and then be able to connect to it using the P4V Client to access the files over the internet form a another household. I no that I'll have to forward some ports and stuff but what set up files do I need to do this? I can only find info for servers that are all being run on the same network like at a business or something nothing that is over the internet. I've set up a team speak server like this where you go to connect and type in the ip address and port and then connect to the server but this dosn't have options like that, that I've seen anyway. This will be done all on Windows 7 64 bit machines. Server on desktop and clients will be on desktops and laptops. All help is appreciated and I'll be posting back with updates on what i'm doing so others can follow this as well if needed.
The server accepts TCP/IP connections, which can be from any client machine which has TCP/IP connectivity. The Perforce server configuration for telling it which IP address and port number to listen at is the P4PORT setting: http://www.perforce.com/perforce/r12.2/manuals/cmdref/env.P4PORT.html
Since you're on a Windows machine, your server will probably be run as a Windows Service, and hence its P4PORT setting will be held in the registry section for that service. You can edit the service's configuration using a registry editor such as RegEdit, or more simply you can use 'p4 set -S Perforce P4PORT=my-host-name:my-port-number' to specify the desired IP address and port.
Then restart your Perforce service from the Services Control Panel and you're good to go!
