Thanks Andy. Im a proper luddite, if you couldnt tell
Filesharing isnt a massive requirement. We have a 'mycloud' that sits quietly as a shared drive so the guys can shove sharing files into that if needed.
Im really just looking to see if theres a more secure/easier way to have 7 computers in this place - maybe it is simplest as it is with all of them individual machines?
Need to know a fair bit more dude, to really scale what you are looking for.... how you work, what you work on, what is important, budget, what applications do you use - any compatibility issues and so on. Priorities being....? e.g Collaboration, speed, resilience, backups, data sharing, cyber posture required, who supports it all, current equipment you have (any networking), plans for expansion, remote access needs....
Easy just to say - without knowing anything....
- use the google suite as your office package and central fileshare/drive. Central router/firewall in some mini network (can be wifi based) if you don't have this already - use the local mycloud as a backup for your central stuff. Ensure unique identities, enforce MFA and password rotation, keep the site FW up-to-date and lock down the rule base, setup alerting etc.
The endpoints just need to be managed. Have Defender or something XDR like sophos home on each - ensure they're checked for updates (for the AV and Windows + any local apps) and on a supportable OS for security updates on monthly cycles You don't need a domain to federate identities unless this is going to be the driver to your systems and is a requirement, such as SSO or you all machine share/hot-desk or whatever.
Failing that - reaching to M365 suite - if you need true MS based integrated and unified working areas and tools. but obvs £
Or... I can let you Windows 2000 server. You can fire up your own domain, DNS, print server and mapped drives.
that last bit is a joke btw
I have NT4.0
