Exhibit 99.9

Avocent to Acquire LANDesk in $416 Million Transaction Creating a Leading
Provider of IT Infrastructure Management and Security Products and Solutions

    HUNTSVILLE, Ala.--(BUSINESS WIRE)--April 27, 2006--Avocent
Corporation (NASDAQ: AVCT), the leading supplier of IT infrastructure
for the centralized management of enterprise data centers, branch
offices and small to medium sized businesses, and LANDesk Group, Ltd.,
of Salt Lake City, Utah, a recognized leader in software for the
centralized management and protection of information technology
assets, today announced that they have signed a definitive agreement
under which Avocent will acquire LANDesk.
    The strategic business combination of Avocent and LANDesk, coupled
with Avocent's recent acquisition of Cyclades, a leading provider of
serial-based infrastructure management products, will reinvent IT
management by offering always-on management solutions that put
information-technology managers in control of all the hardware and
software assets that enable their business services.
    The agreement provides for total consideration of $416 million,
including $200 million in stock, $200 million in cash and $16 million
in assumed options. $60 million of the stock consideration will be
held in escrow for 18 months. The transaction value may be increased
by up to $60 million if LANDesk meets certain financial targets
specified in the agreement.
    Avocent expects the transaction to be accretive to operational
earnings per share in 2006. In 2005, LANDesk achieved EBITDA (Earnings
Before Interest, Taxes, Depreciation and Amortization) of $7.0 million
on revenue of $83.7 million.
    LANDesk has long-term strategic relationships with Lenovo, Intel,
and other major OEMs. LANDesk also has a well-diversified revenue
base, with no end customer representing more than 10 percent of
LANDesk's annual revenues. Approximately 60 percent of LANDesk's
revenue is generated by software license sales to IT customers, with
the balance consisting of support and maintenance fees, consulting and
implementation services and royalties for technology licensed to OEM
customers. Just over half of LANDesk's sales in 2005 were generated in
North America, with the remainder primarily in Europe, Japan, China
and Latin America.
    LANDesk became a standalone, privately held company when it was
spun out of Intel in September 2002. Operating principally in the
enterprise desktop administration market, and with approximately 500
employees, LANDesk has emerged as a recognized leader in the
centralized management and protection of enterprise
information-technology assets, garnering top honors in a wide variety
of industry analyst and editorial forums.
    LANDesk's principal product offerings are the LANDesk Management
Suite (LDMS), a set of integrated desktop management tools, and the
LANDesk Security Suite (LDSS), an integrated security configuration
suite. These tools and processes allow information-technology managers
at medium to enterprise-scale organizations to control their network
of desktops, servers, notebooks and mobile devices by centralizing and
automating complex IT processes and allowing management of a
heterogeneous IT environment from a single console.
    LANDesk also offers several optional LDMS add-on modules including
LANDesk Server Manager (LDSM), LANDesk Process Manager (LPM), LANDesk
Patch Manager (LDPM), and LANDesk Asset Manager (LDAM). Separately or
together, these tools facilitate asset deployment and configuration,
software distribution, software license management, remote problem
diagnosis and repair, operating system migration, fixed asset
discovery, security monitoring and remediation, and IT business
process automation.
    "The acquisition of LANDesk, together with our recent acquisition
of Cyclades, will enable Avocent to offer enterprise customers one of
the most complete range of value-added systems and security management
products and solutions available anywhere, from anyone, creating new
revenue, growth, and value creation opportunities," said John R.
Cooper, chairman and chief executive officer of Avocent.
    "We will be able to offer an expanded management platform
incorporating the best features of our DSView 3 software and LANDesk's
highly regarded, unified architecture. The solutions made possible by
that platform will span multiple IT disciplines, such as server,
desktop, data center, network and security administration, and will
allow us to help our enterprise customers leverage their IT
investments and solve multiple IT-related business problems. The
combination of Avocent's hardware expertise and LANDesk's software
services will also enable us to deliver those solutions in an
appliance and software platform that will provide customers with
solutions that are easier to deploy and maintain than any competitive
offering.
    "We already have a successful working relationship with LANDesk,
which is part of the Avocent Alliance Program for independent software
vendors. We know that the company has outstanding technology, a strong
product pipeline, a large and diverse customer base that complements
ours, and outstanding people in R&D, sales & marketing, field
engineering and customer support. We look forward to working with the
LANDesk team to get the deal done as quickly as possible, and to
deliver the value it will create to our respective customers,
employees, business partners and investors," Mr. Cooper said.
    "Avocent enhances the product suite and services that we can
provide our customers and strategic partners," said Joe Wang,
president and chief executive officer of LANDesk. "LANDesk will
preserve its organizational identity while becoming part of a
well-capitalized enterprise with excellent prospects for accelerated
growth."
    Completion of the transaction, which is subject to
Hart-Scott-Rodino review and customary closing conditions, is expected
to occur within 60 to 75 days.
    Avocent's financial advisor on this transaction was Morgan Stanley
& Co. Incorporated. RBC Capital Markets provided a fairness opinion to
Avocent's Board of Directors. LANDesk was advised by UBS.
