Comparison of two kinds of terminal protocols for Win2000 server

Objective:

The WIN2000 server has two kinds of terminal protocols, one is the RDP protocol of the system, the other is the ICA protocol of the United States Ctrix Company. The author first uses the RDP protocol, in some low-grade 586 microcomputer, WIN95 (98) platform, realize the terminal function of Win2000 server. Later through the use of Win2000 terminal card, gradually understand and master the use of ICA protocol, in the DOS, WIN95 (98) Platform and 386, 486, 586 microcomputer conditions, the realization of the WIN2000 server terminal mode. The following two protocols are compared in several ways.

One, the terminal realization Way

1, the RDP protocol can only be used under WIN3.1, WIN95 (98) platform.

Win2000 server with terminal Protocol RDP protocol, can only be used in WIN3.1, WIN95, 98 platform, through the installation of Terminal Services client software to achieve terminal mode. Chinese version WIN2000 server operating system only provides WIN95 (98) Platform of Terminal Services client software, English WIN2000 server operating system provides Win3.1, Win95 (98) The next two kinds of Terminal Services client software.

2. ICA protocol can be used under DOS and WIN3.1, WIN95 (98) or under other operating systems.

ICA protocol provides 10 kinds of terminal client software, ICA16, ICA32, Icados, ICADOS32, Icaedit, Icajava, Icamac, Icaunix, Icaweb, icawince, full coverage, In several commonly used operating systems can be implemented terminal mode, from this can be seen, Ctrix company in the field of terminal software is indeed a deep foundation. The advantage of ICA protocol is that, in addition to Windows platform, it also provides terminal client software under other platforms, providing great flexibility to users.

We often use four kinds of icaica software, ICA16 for Win3.1,ica32 for WIN95, Icados and ICADOS32 for DOS. ICA16, ICA32 client software is equivalent to the RDP protocol Terminal Services client software, useless more than described. The Icados and ICSDOS32 Terminal Client software provides the conditions for 286 and 386 microcomputers to use Windows large application software under the DOS platform, which is unmatched by the RDP protocol.

In the DOS platform, with floppy disk or hard disk, first through the network client software (NET) login Win2000 Server, and then through floppy disk mode, hard disk mode, virtual memory mode one of three ways, run Icados, ICADOS32 Terminal client software, to achieve terminal mode, Can run WIN2000 server on the large software, such as Office 2000, WPS Offoice, PHOTOSHOP, VB, VF, VC and so on.

Floppy disk mode is mainly applicable to the computer hard disk has been bad situation.

Hard disk mode is mainly applicable to the computer soft hard disk is normal situation.

Virtual memory mode is mainly used to avoid the computer soft, hard disk installation Icados, ICADOS32 Terminal client software, and install it on the Win2000 server, on the floppy disk or hard disk network client software (NET) to log on to the server, The native memory virtual disk that copies the terminal client software from the server and then runs it. Some Win2000 terminal card that uses this principle.

This approach is mainly applicable to the inability to install the Windows 95 (98) operating system of 286, 386 microcomputer, can bring it back to life, reuse, for the primary and secondary schools and enterprises in the early use of 286, 386 computer classrooms built in particular valuable.

Second, drive mapping

1. RDP terminal Client software does not implement drive mapping.

RDP terminal Client software can not map this PC floppy disk and hard disk to the WIN2000 server, the results of the work on the server can only be stored on the server, the end user management files brought difficulties.

2, ICA Terminal Client software can implement drive mapping.

ICA Terminal Client software can map the floppy disk and hard disk to the WIN2000 server, the results of the work on the server can be stored on the computer's soft and hard disk, which brings great convenience to the end-user management files. As shown in Figure 1.
