You don't need to change your host. The IP selection of the auxiliary machine is automatically selected. Then fill in the DNS as if it were the host. That's fine.

To bury the attributes of the shared file on the machine that shared the file, add everyone users to the permissions, and set the permission to Stove Shot All Allow or Read Only.

First of all, the three telegraphs are buried in their brains to establish a working group, and then they can be seen in the small LAN, turn on the file sharing attribute, and then you can see it in the dust worm network where the working group answers empty.

Setup is required, and both PCs need hubs to connect. Then set the IP number (the IP number of the two computers should be different), the subnet mask, and the network management. and then set up as the same workgroup. Then set up sharing for the printer or file.

For example: ip: subnet mask: NMS:

The printer is set to shared. The two computers are connected with a switch, so you should be able to see it.

A switch or cat is required to connect the two computers

Is the computer where the shared file is placed a different operating system?

You can check it, look at my computer, right-click management, local users and groups, users, guest, right-click properties, and see if the "account is deactivated" item is preceded by a checkbox? (The default is ticked), remove this tick, OK, and exit.

If you have changed systems on another computer and you can't see the shared files, you can do the same. It is also possible to set an access password for the guest user, so that the security is much higher.

If you don't see it, you can use it and run cmd "co-co-op file computer IP co-e-op filename" to access the share.

Start this service, as long as the IP of the two computers is in the same network segment, it is best not to open the firewall, and file sharing only needs the right mouse button "Share and Security", check the share of the folder on the line, if it is a simple folder sharing, you must enable the guest user.

Start running your IP address d$ on his machine (let's say it's a D drive) and see if you can set up an account on your machine and set a password.

Set up the same account on his machine, the password is the same as your local one, right-click on the hard drive partition - share and secure share - share this folder - permissions - join your new user.

Security - Join the newly created user.

Let him log in to the system with a new account, and the second method of your IP address should be fine.

Add a $ in front of the share name so that others can't see the share, and tell the other computer the path to the person.

On the computer with the printer, view the printer, right-click to set it to share, use the one without the printer, install the network printer, select it after browsing, and then install OK step by step.

Share this printer in the printer options in the computer that connects to the printer, and then in another computer that does not have a printer, you can search for this printer in the network neighbor, or you can add a network printer in the printer options, and the driver will be installed by itself.

To reset the local area network, follow the steps below:

1. The working group should be the same. How to do it: Right-click on My Computer Properties Computer Name to change the workgroup.

2. Disable the "guest" account. Operation: Right-click My Computer Manage Local Users and Groups, Double-click the user, click Guest, right-click, Properties, and check before Account is deactivated.

3. Change the security and sharing mode of the local account to classic. Specifically, go to Settings Control Panel Performance and Maintenance Management Tools Local Security Policies Security Options Network Access

For the sharing and security mode of the local account, select "Classic: Local users with their own authentication".

4. If you want to share files and printers, you need to turn on the sharing of each machine.
