You have cloud storage so if this works well for you then keep using this. To then be able to share files on your new workgroup - especially with Windows Vista, 7, 8, 8.1 and 10 - you should create a HomeGroup where this will allow you to share files if you keep them on your LAN.

When the computer is joined to the new workgroup you will be asked to restart your computer - do so as this is crucial.

You may be asked to provide local Administrator account details again.

Sysdm.cpl (that’s a lowercase L) opens the System Properties screen from the command line. Press Windows Key + r to open the Run window then type.

Enter a workgroup name - you will need to re-use this on the other computers Here you can see it matches the account I want to remove so I can safely delete this key by right clicking the SID in the left pane and choosing Delete.

to rename this computer or change its domain or workgroup The above commands work on Windows 7, Windows 8, XP and also on all Server editions. Note that we do not need to specify the domain name in this command. You need to have domain administrator privileges to perform this operation.

If you want to create OUs in a different domain, right-click the Active Directory Users And Computers node in the console tree, and then select Change Domain. To delete a user account from domain: net user username /DELETE /DOMAIN.

A new window will open with some tabs - Click the first tab Computer Name By default, you are connected to your logon domain.

Under Computer name, domain, and workgroup settings click Change settings - you will need to have the local Administrator account details to hand.

To remove the computer from the domain all you need is a local administrator username and password to put the computer back into a Workgroup. You will also lose any Group Policy settings and security groups that the domain provided. It would be easier to remove the computer from the domain and you will then have a standalone machine as you originally purchased. It shouldn't harm anything by keeping the machine as part of a domain, however, it makes no sense to keep it on a domain if you have no domain controller to manage the trust between your computer, the DC and the other computers on your domain.

The company who removed the server should really have informed you about what happens when a domain-joined computer has no DC to contact and some of the things you'll notice you can or can no longer do since the computer is still part of a domain.
