Citrix UNIX Integration Services Extends Windows-Based Application Access to X11 Devices; New Product Expands Client Connectivity to Citrix MetaFrame and WinFrame Servers.

FORT LAUDERDALE, Fla.--(BUSINESS WIRE)--July 28, 1999--

Citrix Systems, Inc. (Nasdaq:CTXS) today announced Citrix UNIX(R) Integration Services, a new product in the Citrix Management Services product family that enables devices supporting the X11 protocol to access Windows-based applications running on Citrix MetaFrame(TM) for Microsoft NT Server 4.0, Terminal Server Edition, and WinFrame(R) servers. UNIX Integration Services offers Windows-based application access to the more than six million desktops supporting the X11 protocol, including all leading X11 terminals and UNIX(R) workstations, as well as Macintosh computers and PCs equipped with third-party X11 display software. Included with UNIX Integration Services are numerous tools that provide additional integration between Windows NT and UNIX environments.

"By expanding the reach of MetaFrame and WinFrame to X11 desktops, UNIX Integration Services provides our customers with even greater connectivity options," said Steve Piper, senior product manager. "Citrix is committed to extending Windows-based application access to virtually any client, from the latest handhelds to older devices. We believe organizations should be able to quickly and cost-effectively deliver the same applications to every user, even within a heterogeneous computing environment."

Citrix already provides MetaFrame and WinFrame connectivity to all leading UNIX platforms via feature-rich Independent Computing Architecture (ICA(R)) clients. Customers electing X11 solutions, which do not support ICA and are optimized for LAN deployment, now can implement UNIX Integration Services to provide LAN access to Windows applications running on Citrix MetaFrame and WinFrame.

UNIX Integration Services, designed to provide X11 devices with basic connectivity to Citrix MetaFrame and WinFrame servers, does not offer ICA features such as load balancing, published applications, and low bandwidth connectivity. The new product can be installed on MetaFrame 1.8 and 1.0, and on WinFrame 1.8 and 1.7.

UNIX Integration Services offers the following additional features:

-- Network Information Services (NIS) support - allows UNIX user accounts to be imported into a Windows NT domain and enables UNIX/NT password synchronization

-- Common Desktop Environment (CDE) integration tools - allow users to launch server-based applications via native Windows icons and file associations

-- Xcapture - enables users to copy and paste graphics between X11 desktops and X11 MetaFrame/WinFrame sessions

-- Shadowing - allows shadowing of X11 sessions from other X11 sessions

Pricing and Availability

UNIX Integration Services will be available to distributors today, and members of the Citrix Solutions Network may place orders immediately. The suggested retail price is $1,495 per server.
