Small Businesses need enterprise level technology to compete. Microsoft has effective technologies, but if you are not a non-profit Windows can get really expensive fast. What if you could get the same functionality for a substancially reduced price? Wouldn't you consider it, even if it wasn't a Microsoft product?  There are many alternatives to a Windows Active Directory Infrastructure without all the probelms of viruses, malware, security bugs or in some cases, cost.

Novell has the predecessor to Active Directory call Netware (the first commercial LDAP Forest / Domain offering)

Apple has it's Worgroup Servers integrated with LDAP.

Linux has OpenLDAP, Fedora and RedHat Directory Services, Kerberos, NFS (compatible with Windows and Mac OS X)

We offer solutions for E-mail & Groupware, Customer Relationship Management (CRM), Storage,  Domain Security, Firewalls & Remote Access (VPN), networking,  any any other type of IT service need your comapny might need.

Soon the great team at Samba will release Samba 4 - an alternative to Windows AD on Linux. This means that you can join your Windows 2000, XP, Server 200x.
