Windows Terminal Server • What is it? • Why is SLAC using it? . • Significant Deployment issues • Future Directions • Demos 3 -Dec-1998

WTS, Citrix Metaframe, Hydra… • Built on the original Citrix Winframe product. • Adds/is a true multi-user to NT 4. 0 • Thin Client’s access to Win 32 services • MS provides RPD Client • Citrix Provides ICA Clients, Farms, Strong Encryption, … 3 -Dec-1998

Microsoft RDP • • Remote Desktop Protocol Based on Same protocol as Net. Meeting Currently only TCP/IP support. Full Desktops or limited application publishing • Win 16, Win 32 clients only. 3 -Dec-1998

Citrix Metaframe • • • 3 rd Party Add-On - get it Better Management Application Publishing Server Farms Web based applications 3 -Dec-1998

ICA Intelligent Console Architecture • Dos, Win 16, Win 32, SCO, Solaris, HPUX, SGI, Linux, Mac. OS, Active. X, Netscape, Java. • Uses ~ half bandwidth (28. 8 k works well) • Printer, Serial port, Disk, re-directors • Better encryption (RC 5 vs. RC 4) 3 -Dec-1998

SLAC Applications • Taming and securing People. Soft 6. 0 Deployment • Instant change control and enhanced security. • Application Services for BABAR • Standard office applications, some CAD • Possible VNP / Remote Access solution. 3 -Dec-1998

Description of SLAC WTS environment • Really powerful Workstations • Dell Power. Edge 2300’s • Dual PII 400’s, 1 Gig, RAID 1 SCSI 3, 100 MBit Switch Ethernet • ~35 - 40 users. • WTS boot floppy for consistency 3 -Dec-1998

Deployment Issues and Gotchas • Everything you know is wrong • Local access but not network access. • Very little 3 rd party support or documentation. • 2048 Open Files per SMB Circuit • Expensive! 3 -Dec-1998

What works and what doesn't • • • Most MS Win 32 Apps Win 16 and DOS apps should be avoided Not useful for a batch job processor No free software. Expect to get the first few wrong. 3 -Dec-1998

Where Does Microsoft Want Us To Go? • Common Code Base after SP 4 • WTS v 2. 0 is a part of Win. NT 5. Server • Might be part of Workstation ( Personal Terminal Server? ) • IPX, Net. Bios, Netbeui, Async support • RDP absorbs some ICA capabilities • Thin Clients to the AD? 3 -Dec-1998

Demo! • Surprise, this is running from SLAC! 3 -Dec-1998
