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?
