In an office setup, we have PC1 and PC2 , Windows 10 Pro. NO INTERNET CONNECTION (Our boss won't allow it)

We have a LAN cable going from the modem/router to PC1 and another to PC2.

We need to network PC1 and PC2, so that each one can see the other on the network and can share files and have read/write access. But we need to do this, without internet access.

We are installing Simply accounting and we need to make it so that when PC1 makes a change, it reflects on PC2 and vise versa.

We know it's possible, because we did it on Windows Vista with an old version of Simply accounting and everything worked fine, But we just upgraded to 2 new PC's, windows 10. The LAN cables haven't changed or been moved. All we did was replace the two PC's. So we just need to get them linked up. I know it's simple to do with Homegroup but don't you need an internet connection for that? Please reply asap. On the old systems, they appeared when we went under Network....we could see the other PC. Hoping it will more simple with Win 10. Thanks.

When you're connecting in areas where there will be no internet service, you need to have a router that your laptop and your iPad can connect to (or another desktop). If you don't have a router then you will need to setup an Adhoc network on your computer.

Once you've got both devices on the same Wifi/Adhoc network, you'll need to find your PC's IP address by opening up the command prompt and typing in the following and pressing enter: ipconfig . Look for the value of "IPv4" address. Thats your IP address.

Finally open up Jump and make a note of the text underneath your computer's name in Jump - it should say "Windows Remote Desktop" or "Secure Screen Sharing".

If in the last step, it says "Secure Screen Sharing", then you need to do two additional Steps on the PC: Open up "TightVNC" by clicking the V icon on the bottom right hand corner of your desktop.

Look up the value of "Main server port" - it should be a number like 5900 or 5907 or something similar.

Then click on "Access Control" and uncheck the "Allow loopback connections only" option.

On the iPad open up Jump and then tap the + button on the top right. Then in the "Address" section enter your computer's IP address that you found in #2. In the Type section select "RDP" if in #3 it said "Windows Remote Desktop" or "VNC" if it said "Secure Screen Sharing". If you selected "VNC" be sure to edit the "Port" field and make sure it matches the port # number you looked up in 4a.

Save your settings

Try to connect to the computer.

Note: Your IP address may change every time you connect to a different wifi router. So you need to double check your ipaddress before attempting to connect.

Also, here is how to create an adhoc wifi spot:

Step 1: Step 1: Right click on Start button or press the Windows + X keys to open the power user settings panel, and launch Command Prompt (Admin) to get started.

Step 2: Enter the following command, hitting the Enter / Return key at the end. To name your Ad hoc connection, simply replace “adhocname” with a name of your choice, and to change the password, replace “password” with one of your choice::

netsh wlan set hostednetwork mode=allow ssid=adhocname key=password

Step 3: Enter this one last command and hit the Enter / Return key:

netsh wlan start hostednetwork

Step 4: Open the “View network connections” window, which can be found easily by searching for it using search bar in the Taskbar.

Step 5: Right-click your Ethernet connection and select Properties and switch to the Sharing tab.

Step 6: Check the “Allow other network users to connect through this computer’s Internet connection” option, and choose the newly created WiFi connection from the drop down list located under “Home networking connection”.

You can now connect to your newly created WiFi access point using whatever smartphone, tablet or computer you had in mind. You will also be able to see the new connection as active in Network and Sharing Center.

If you wish to disable the hotspot at any given time, simply enter the following command in Command Prompt with Administrator privileges and hit Enter:

netsh wlan stop hostednetwork

I hope this was of help to you
