First, any server and that would include a main computer, should have a static IP. But, if you are peer-to-peer, then by default, your IP will generally always be the same since you don't have a DHCP server unless, of course, your router is giving out IPs. Either way, your main computer you be static.

You can get to your NIC or Network adapter via Network and Sharing Center in Win 7, likely relatively the same in Windows 10.

Here you will see a network adapter which is set up to be dynamic and the DHCP server either on the server or router will give it an IP. This is generally best for clients, because router DHCP server (the "server" which gives out IP address and default gateways and DNS) generally doesn't screw up. Most of client will maintain their same IP even when it expires, but there is always the possibility that the DHCP server will assign it another IP. This is why most hardware like printers and scanners are set up with a static IP. But, if the "main computer" is given a different IP, there could be problems. This is why using the name is safer as it doesn't change. However, if you do change the name, which would be done manually, then all clients pointed to that computer would no longer be connected. Therefore, if you used an IP address (which was static) meaning it would ALWAYS be that IP and you connected via that address \\192.168.10.2\Amazing Charts for instance. Either way you are connecting to the same main AC and SQL server. The path is the same, you are simply using the IP address of the "main computer" vs the name of the "main computer."

In the example above, you would click the radio button to use the following IP address, and type in the IP address manually. Easiest to just use whatever settings you had previously if it were assigned automatically. Using ipconfig at a command prompt. Using the ipconfig command will give you your subnet mask, default gateway (has to be the same on all computers), your DNS and your IP. You just need to keep the same subnet, ie. if you were 192.168.10.x, your IP would have to be 192.168.10.x where x is any number between 2 and 254 (assuming your gateway is x.1 -- of course, you can't use any other IP that is in use currently). But, just easiest to use the current settings. If they are already in the Use the following IP address, then it is already static.

For some reason, using the IP address is sometimes better, although I have seen it work better for some who have difficulty connecting to AC and not so much crashing. It is simple to try. if you aren't sure what the current IP is you can pull up a command prompt: Run -> type "cmd" without the quotes, then you type: ipconfig to get the network settings for that computer, i.e.

C:\users\username>ipconfig

192.168.10.2
255.255.255.0
192.168.10.1

If you wanted more information, say the computer were connected to an actual server or router giving out settings, you would type: ipconfig /all

HTH. I tried to make it as confusing as possible.

This is something John Ryango has suggested for months.
