Advantages of Linux

Linux is capable of handling many aspects of an NT network or Domain.

For example, the mainstream tasks such as E-mail (sendmail), FTP, HTTP, Telnet, and other such servers are in my opinion pretty much default.
However, Linux is capable of much more than mainstream. For example, using a SAMBA server Linux can participate in NT/2000 file sharing. Linux is even capable with the proper configuration of being an NT domain controller (PDC).

Linux has been built as a fax server system.

I myself use Linux to provide a central storage server (using SAMBA), and web services.

Other uses of Linux:
Firewall, Workstation, Graphics/Engineering Workstation.

I have used Linux as a replacement of Windows NT Server and PDC a lot of times, always with great results. As a file server with RAID support with really big partitions, with backup capabilities, for domain access control. As a file server you will need less resources than needded by Windows NT, so the server's performance is greater. Linux has no real cost and once a machine has passed a good test and configuration improvement it will work for months without human activity. There is no need for a Backup Domain Controller, you can build the server with LDAP (Lightweight Directory Access Protocol) to supply Active Directory capabilities, but I didn't tryied it yet. You can build a high reliability Cluster (Fos, Balancer, etc.) spending just one day of work! It may give more supporting services as told above and such as VPN gateway!
