On one hand, the company seems to have embraced the idea of multiuser Windows. In July 1998, Microsoft came out with a multiuser version of Windows NT 4.0 to support users who want NT on the desktop but also want the advantages of a multiuser OS. The company is taking this concept a step further with Windows 2000 Server (Win2K Server), which includes terminal services built in to the core OS in the form of a service that you can choose to install, such as Internet Information Server (IIS) or Network Monitor. Recognizing that having remote control of a server is a terrific administration tool, Microsoft even offers you the option in Windows 2000 (Win2K) of installing terminal services just for remote administration--after all, not everyone needs these services for application serving. Pretty cool. On the other hand, Microsoft seems unsure whether it wants people to use its terminal services. The Windows NT Server 4.0, Terminal Server Edition beta version was working pretty darn well, so why not showcase it at TechEd '98? Microsoft could have used Terminal Server to power multimedia kiosks and demonstrated a potential application for multiuser Windows. Maybe the company didn't want to use beta software. But terminal services technology was hard to find at the Microsoft Professional Developers Conference in October 1998, too, and Terminal Server was out in July. Microsoft provided a couple of introductory sessions on terminal services at TechEd '99, but not only were those sessions extremely basic, the presenter for one session was so unfamiliar with the topic that the audience had to prompt him--and correct him--when he didn't know answers to simple questions such as whether Terminal Server supports session shadowing. If Microsoft wants to push terminal services, why didn't it offer high-end presentations on the subject, as it did for other technologies? Then there's licensing. When terminal services first came out, Microsoft required you to buy an NT Workstation license for any computer that would access the terminal server. After realizing that people weren't going to pay that much, the company reduced the licensing fees in February 1999, but it's still expensive. At this point, you can essentially choose between two types of licenses: terminal server client-access licenses, which you use to connect users with accounts on the domain, and Internet client-access licenses, which you use to connect anonymous users accessing the terminal server via public networks. In other words, the Internet client-access licenses are useless to you unless you're an application services provider (ASP). Even if your network runs across the Internet, you can't use those Internet client-access licenses for employees, which makes terminal services expensive on a large scale. A few days ago, I talked with someone who manages terminal services for a corporate WAN extending over much of the eastern United States. He mentioned that although he had about 1800 users, he was limiting terminal services to 400 users. "Hardware restrictions?" I asked. "No," he replied, "licensing." People are interested in having terminal services to publish applications for their employees--no doubt about it. I like Terminal Server, and I really like how Microsoft is fitting terminal services into Win2K. I just wish I were sure that Microsoft is firmly behind terminal services, and not just supporting it grudgingly. See you next time, Christa Anderson, Thin-Client UPDATE News Editor [EMAIL PROTECTED] ========== THIN-CLIENT NEWS AND VIEWS ========== (contributed by Christa Anderson, [EMAIL PROTECTED]) * CITRIX TEAMS WITH SOCKS FOR GREATER SECURITY On August 23, 1999, Citrix Systems announced that it's strengthening the security of its Independent Computing Architecture (ICA) display protocol with support for SOCKS versions 4 and 5. This widely used industry proxy protocol serves as a network firewall that lets hosts behind a SOCKS server gain full access to the Internet while preventing unauthorized access from the outside. The increased security should push greater deployment of server-based computing via the Internet. SOCKS enables ICA to provide a highly secure method for controlling traffic through a corporate firewall by letting hosts on one side of the SOCKS server gain full access to hosts on the other side, without requiring direct IP access. Previously, a company wanting to provide Internet-based application access either had to open a port in its firewall--generally considered a breach of network security--or implement a costly VPN. Citrix ICA will support SOCKS version 5 to ensure that users receive the latest features and functionality and version 4 for compatibility with older devices. The company will add support for SOCKS to Citrix MetaFrame clients over the coming months. You can get an updated version of the Macinosh ICA client now (most Macintosh users access Citrix servers via public networks, so Citrix updated that client first). Citrix expects to release the Java 4.11 and Windows CE ICA clients, with support for Program Neighborhood as well as SOCKS support, this month. The company plans to update all ICA clients, including DOS, Win32, Win16, and ActiveX, by December 1999. For more information, check out Citrix's Web site at http://www.citrix.com. * GRAPHON AND SIMPLE FUTURE ANNOUNCE ALLIANCE On August 18, 1999, GraphOn Corporation announced that it has signed a strategic reseller agreement with Simple Future, a networking specialist and systems integrator in thin-client and security technologies. Using GraphOn's GO-Joe, GO-Global, GO-Between, and jBridge thin server-based connectivity software, Simple Future will provide enterprises with next generation Linux, UNIX, and, when it's released, Windows NT application delivery over networks of all kinds, including Web-enabling applications for delivery over the Internet--the emerging model for application service providers (ASPs). For more information, see GraphOn's Web site at http://www.graphon.com. * CITRIX AMONG FASTEST-GROWING US COMPANIES Fortune Magazine has ranked Citrix Systems among the top five in its annual list of the 100 fastest growing companies. Citrix, the leader in the server-based computing software marketplace, earned its fifth-place ranking with earnings per share growth of 100 percent, revenue growth of 140 percent, and total return of 65 percent--all over a period of just 3 years. When Fortune Magazine considered revenue growth alone, Citrix ranked eighth. To be considered for the Fortune list, a company must be based in the United States, have been in business for at least 3 years, and have a market capitalization of at least $50 million. In addition, a company needs to show sales and earnings per share growth of at least 30 percent a year for 3 years. The magazine also factored in each company's stock market returns since 1996. According to Fortune Magazine, "Not only have these 100 businesses posted staggering gains in profits and revenues, but many have also produced impressive returns for investors." ========== ANNOUNCEMENTS ========== * WINDOWS NT MAGAZINE PRESENTS A BRAND NEW NEWSLETTER--IIS ADMINISTRATOR!

Microsoft Support Online article Q193386 (http://support.microsoft.com/support/kb/articles/Q193/3/86.asp) reports that the Windows NT Server 4.0, Terminal Server Edition licensing service uses the file, and you can't update a file that's in use. Turn off the licensing service, install SR2, and restart the service. * WHICH HOTFIXES ARE COMPATIBLE WITH TERMINAL SERVER? Windows NT Server and Windows NT Server 4.0, Terminal Server Edition can't use the same hotfixes because the two OSs are structurally different. According to Microsoft Support Online article Q196334 (http://support.microsoft.com/support/kb/articles/q196/3/34.asp), you can use the FileVer tool in the Microsoft Windows NT Server 4.0 Resource Kit (Supplement 2 or later) to determine whether a hotfix is intended for the single-user or multiuser version of NT Server 4.0. * PROBLEMS CONNECTING MULTIPLE TERMINAL SERVER CLIENTS When multiple Windows NT Server 4.0, Terminal Server Edition clients try to connect to Windows Terminal Server, Service Pack 4 (SP4), you might receive notification of unsuccessful logons, and you might find an Event ID 22 in your logs. Microsoft Support Online article Q238186 (http://support.microsoft.com/support/kb/articles/Q238/1/86.asp) explains the problem and tells you how you can get a copy of the fix. * LOST PROFILE SETTING CHANGES TO TERMINAL SERVER CLIENTS If you have a Windows NT Server 4.0, Terminal Server Edition client that's losing changes to its profile settings, the user's copy of the Win32 subsystem (csrss.exe) might be keeping the user's profile open. Turn to Microsoft Support Online article Q234606 (http://support.microsoft.com/support/kb/articles/Q234/6/06.asp) for a Registry hack that will resolve the problem. * THE "TEMP DIRECTORY NOT ACCESSIBLE" ERROR MESSAGE If Windows NT Server 4.0, Terminal Server Edition with Service Pack 4 (SP4) crashes, you might get an error message telling you that the temporary directory is not accessible when you restart the system. Terminal Server SP4's method of securing temporary directories causes the problem. Typically, when you reset a Terminal Server session, the WinLogon service deletes your temporary directories to keep other people from viewing the contents. If the server crashes, WinLogon never gets the chance to delete the files, and the temporary directories are orphaned. Check out Microsoft Support Online article Q234029 (http://support.microsoft.com/support/kb/articles/Q234/0/29.asp) for a workaround and instructions for getting a fix from Microsoft Support. * TERMINAL SERVER CONNECTION REQUEST FLOODING (contributed by Mark Joseph Edwards, [EMAIL PROTECTED]) Microsoft released a patch that eliminates a vulnerability discovered by Internet Security Systems (ISS). The problem can lead to a denial- of-service threat against Windows NT Server 4.0, Terminal Server Edition. During a connection attempt from a client, Terminal Server undertakes a resource-intensive series of operations to prepare for the connection. These operations take place before the OS authenticates the client. Because of this situation, an attacker could deny service to the Terminal Server by flooding the machine with several connection requests, which can eventually consume all available memory on the machine. Filtering incoming Terminal Server connections can help reduce the chance of this issue becoming a problem. See Microsoft Support Online article Q238600 (http://support.microsoft.com/support/kb/articles/q238/6/00.asp) for more information. ========== NEW AND IMPROVED ========== (contributed by Donna Diduch, [EMAIL PROTECTED]) * SEND FAXES FROM ANY NETWORKED DESKTOP DPD International announced Gold-Fax 5.1, enhanced, scalable fax software with a new Web browser interface that lets users send faxes from networked desktop systems such as Windows NT Server 4.0, Terminal Server Edition and Citrix WinFrame. Version 5.1 provides graphs of faxing activity so users can determine peak use periods; lets users set fax-sending priorities and view sending fax numbers when the sender routes the fax as email and the recipients enable Caller ID; archives sent faxes; and supports additional modems. GoldFax 5.1 runs on NT and Microsoft Exchange Server.

Contact Citrix, 800- 437-7503. http://www.citrix.com ========== PICKS OF THE WEEK ========== * HOT THREAD: AUTO-CREATE OUTLOOK PROFILES ON TERMINAL SERVER? The following text is from a recent threaded discussion on the Windows NT Magazine online forums (http://www.winntmag.com/support). When running Microsoft Outlook on Terminal Server, is it necessary to have a separate user profile for each user? Currently what I must do is log on as the user and manually create their mail settings to access the Exchange server. What I would like to do is use one mandatory profile for all users, and auto-create their mail profiles every time they log in. Citrix's Web site references a Microsoft article "Automate Outlook Profile Creation Using PRFPATCH". I found this article in TechNet and followed the instructions, but the prfpatch.exe has no effect on Terminal Server. There are also other utilities like the iexpress deployment kit and newprof.exe from Microsoft that I have tried with no luck. If anyone has a workaround I would love to hear about it. Thread continues at http://www.winntmag.com/support/Forums/Application/Thread.cfm?CFApp=69&Threa d_ID=23425&mc=4 * TIP: DETERMINE THE AVERAGE BANDWIDTH USED BY TERMINAL SERVER CLIENTS (contributed by Sean Daily, [EMAIL PROTECTED]) Q: I'm doing capacity planning. How can I determine the average bandwidth used by Windows NT Server 4.0, Terminal Server Edition client sessions? A: Although Microsoft claims that each terminal client session will use 2-6Kbps of network bandwidth, I have found that this estimate isn't always accurate. To get a more accurate picture of how Terminal Server sessions will affect your network, you can use Network Monitor in conjunction with Performance Monitor. First, install the Network Monitor Tools and Agent in the Services tab of the Network Control Panel. This will add the Network Segment object to Performance Monitor (the other object you'll need--Network Interface--should already exist as it installs with TCP/IP). Monitor the %Network Utilization counter of the Network Segment object to track the total bandwidth being used on the network segment where the terminal server is. The Network Interface object's Bytes received/second and Bytes total/second counters provide the total bytes received or processed (respectively) by the server's adapter. If possible, use the version of Network Monitor that comes with Systems Management Server (SMS) or a third-party software product such as Data General's NetXRay, not the NetMon that comes with NT or Windows 2000(Win2K). NT's NetMon can only monitor the traffic to and from its own adapter, and I've found this version's % Network Utilization counter to be unreliable at times, especially on Fast Ethernet and 100Mbps networks.
