Windows Terminal Server
•What is it?
•Why is SLAC using it?.
•Significant Deployment issues
•Future Directions
•Demos

WTS, Citrix
Metaframe, Hydra…
• Built on the original Citrix Winframe
product.
• Adds/is a true multi-user to NT4.0
• Thin Client’s access to Win32 services
• MS provides RPD Client
• Citrix Provides ICA Clients, Farms, Strong
Encryption, …

Based on Same protocol as NetMeeting
Currently only TCP/IP support.
Full Desktops or limited application
publishing
• Win16,Win32 clients only.

•
3rd Party Add-On - get it
Better Management
Application Publishing
Server Farms
Web based applications

ICA Intelligent
Console Architecture
• Dos, Win16, Win32, SCO, Solaris, HPUX,
SGI, Linux, MacOS, ActiveX, Netscape,
Java.
• Uses ~ half bandwidth (28.8k works well)
• Printer, Serial port, Disk, re-directors
• Better encryption (RC5 vs. RC4)

Description of SLAC
WTS environment
• Really powerful Workstations
• Dell PowerEdge 2300’s
• Dual PII 400’s, 1 Gig, RAID1 SCSI3,
100MBit Switch Ethernet
• ~35 - 40 users.

Deployment Issues
and Gotchas
• Everything you know is wrong
• Local access but not network access.
• Very little 3rd party support or
documentation.
• 2048 Open Files per SMB Circuit
• Expensive!

What works and what
doesn't
•
•
•
•
•
Most MS Win32 Apps
Win16 and DOS apps should be avoided
Not useful for a batch job processor
No free software.
Expect to get the first few wrong.

Where Does Microsoft
Want Us To Go?
• Common Code Base after SP4
• WTS v2.0 is a part of WinNT 5.Server
• Might be part of Workstation ( Personal
Terminal Server?)
• IPX, NetBios, Netbeui, Async support
• RDP absorbs some ICA capabilities
• Thin Clients to the AD?
