Applies to: Forefront Protection for Office Communications Server

The following are the minimum server and workstation requirements for FSOCS.

Note

All minimum system memory and disk space requirements for OCS 2007 or OCS 2007 R2 should be met before installing FSOCS. Too little available memory or disk space may impact the ability of FSOCS to scan large files.

Minimum server requirements

The following are the minimum server requirements:

  • Server software:

    • Microsoft Windows Server® 2003. For OCS 2007 R2 the following Operating Systems are supported (64-bit hardware only): Microsoft Windows Server 2008, Microsoft Windows Server 2003, Microsoft Windows Server 2003 R2.
    • Microsoft Office Communications Server Standard Edition, or, Enterprise Edition with one of the following server roles configured: Front End, Access Edge, Director.

  • 1 gigabyte (GB) of free memory, in addition to that required to run OCS (2 GB recommended).

    Note

    With each additional licensed scan engine, more memory is needed per scanning process.

  • 2 GB of available disk space. This is in addition to the disk space required for Microsoft OCS.

  • 1 gigahertz (GHz) Intel processor.

Minimum workstation requirements

The following are the minimum workstation requirements:

  • Windows Server 2003, Windows® 2000 Professional, Windows XP, or Windows Vista®.
  • .NET 2.0, for an Administrator-only installation
  • 6 MB of available memory.
  • 10 MB of available disk space.
  • Intel processor, or equivalent.

Requirements for a service account

During the installation, you are asked for a domain account (on the Service Account Requirements page). The requirements for this account depend on whether the installation is for an access edge role or for another type of role.

Access edge role requirements

  • The account must have the "Logon As Service" privilege. This privilege is automatically granted by setup if not already enabled on the account.
  • The account must be a member of the "RTC Server Applications" local security group. The account is automatically added to this group by setup if necessary.
  • The account must be a member of the "RTC Server Local Group" local security group. The account will automatically be added to this group by setup if necessary.
  • The account must be a member of the "Performance Monitor Users" local security group. The account will automatically be added to this group by setup if necessary.

Standard Edition, front end, or director role requirements

  • The account must have the "Logon As Service" privilege. This privilege is automatically granted by setup if not already enabled on the account.
  • The account must be a member of the "RTC Server Applications" local group. The account will automatically be added to this group by setup if necessary.
  • The account must be a member of the "RTCUniversalServerAdmins" and "RTCProxyUniversalServices" domain groups.

Failure to meet these requirements results in the installation ending prematurely and the Office Communications Server front-end service being unable to start.
