Linux ClearOS to rival Microsoft’s SBS

Microsoft has dominated the small enterprise market with its out of the box feature rich SBS (Small Business Server). Linux has always trailed behind it and although most of the technology to rival Microsoft has been in place, it has always been a mammoth task to setup a server from scratch  to do that.  ClearOS came to fill in this gap.

“ClearOS is a powerful network and gateway server designed for small organizations and distributed environments.  Though ClearOS comes with an extensive list of features  and integrated services, the solution is easy to configure thanks to the intuitive web-based interface.” (extracted from Clear Foundation website)
 
Take a look at how ClearOS’ features match the MS SBS:

Microsoft SBS

Centralized Authentication (Active Directory)
Mail, calendaring and instant messaging (Exchange)
Webserver (IIS)
Firewall (ISA)
Content management system (Sharepoint)
Antivirus (Forefront)
Database (MS-SQL Premium version only)
Remote Desktop Services
Virtual Private Network (VPN)

ClearOS Linux

Centralized Authentication (LDAP)
Primary Domain Controller (Samba)

Antimalware (Clam Antivirus, Antiphishing, Antispyware)
Antispam (Spamassassin)
Database (MySQL)
Virtual Private Network (IPSec, OpenVPN, PPTP)

The Linux Magazine published an in depth article comparing and explaining this “new” Linux distro.

Server 2003 – removable storage database failed to load

When trying to start the Removable Storage Service it may hang and stop responding. You may get the following error messages:

  • Backup cannot connect to the Removable Storage service. – This service is required for use of tape drives and other backup devices.
  • REMOVABLE STORAGE – Server Execution failed.
  • The removable storage database failed to load. Check the event log.

To fix this just follow these simple steps.

  1. Copy all files located in the %SystemRoot%\System32\NtmsData folder to another location (don’t delete them for now just for safety)
  2. In the Computer Management tool, double-click the Services and Applications branch to expand it, and then click Services.
  3. Locate the Removable Storage service, try to start the service, or change the startup type from “Disabled” to “Automatic”, and then restart your computer. This should import the database from the export folder, build a new index file, and be consistent from when the last %Systemroot% backup was performed.
  4. Done

See the Microsoft Knowledge Base:235032 in case you continue to have the same problem.
