Firewall,Domain or not

Hi There,

What is the max users within a single LAN limit before you need to switch to a domain or firewall for DNS functions and so on?

Thanks in Advance

you could have 1000 machines connected to a NAS in workgroup mode. There are no hard and fast rules. Sometimes outside parties i.e. PCI compliance make a domain the only logical choice and you could have only 1 user (the owner of the company)

To select between domain or workgroup usually less than 10 is for workgroup and more than 10 is for domain.
Firewall to access internet? thats depends of your budget, but ever is a plus. Go to firewall if you can.

The Firewall would be serving multiple roles. So you say more then 10 users; go for either domain or firewall with DNS functions? You prefer Firewall?

Yup that's my question(Nothing specific). how many users until you should be thinking about implementing a DNS function.

There are no hard and fast rules.. Either within a work-group or a domain each computer should have a working firewall to supplement the router's firewall and inherent addition of security by requiring Network Address Translation. The use of a domain greatly enhances the administration of multiple computers and other functionality that is added by having a server doing the heavy lifting.. I've worked for call centres that the telemarketers machines were not joined to a domain and only the administrative / management computers were members of the domain.  There could be 50-100 pc's per call centre room.  

Ten computers sharing files seems to be a reasonable maximum given a client computes limited number of simultaneous connections and a server operating system is required.. since Active directory comes as a free item with server O/S's it is probably prudent to take advantage of it.
