Installation guide

called requester's. The requester's are specified in the config.sys file
and loaded at boot. Network communication is provided to and from the
requester's and protocol's using NDIS (Network Driver Interface
Specification). eComStation ships with these requesters: IBM LAN,
3270 Emulation, Netware (via ThirdParty eCSGuide) and IBM TCP/IP.
These requester's also have their associated protocol drivers as
described previously (TCP/IP, 802.2, etc.). A very extensive online book
"MPTS Configuration Guide" has been placed in the Online Information
folder in the Help Center of your desktop.
When properly configured, eComStation is able to
communicate/network with:
! Windows 95/98/Me
! Windows NT/2000
! Linux (Samba)
! Netware
! and more
Networking Interoperability: Windows
You will need to install File and Printer Sharing to interoperate with a
Microsoft Network. The eComStation client is very easy to setup to
interoperate with a Microsoft Network if you know the tricks involved.
The "File and Print Client Guide" is placed in the Online Information
folder of the Help Center when you installed File and Printer Sharing. It
contains a brief section on interoperability with Microsoft Networks. The
three protocols generally needed to interoperate with Microsoft
Network's are TCP/IP, NetBios, and NetBios over TCP/IP. The NetBios
protocol is used locally on a subnet because it contains no routing
information. This also means that NetBios cannot see past a router
without help. NetBios over TCP/IP can see past a router and this
protocol is generally used at corporate sites where large segmented
networks are the norm.
Windows NT
An eComStation client can take advantage of Microsoft Network in one
of two ways. The eCS client can logon to the NT domain or logon
locally. However, browsing is severely limited on a Microsoft Network if
the servers have been configured with the default settings (more on this
in a later section). Either method will achieve the desired results, to use
the resources on a Windows NT server domain. One precaution, your
local eCS logon must exactly match the logon ID on the NT
domaincontroller. In addition, NT server allows lower case in passwords
whereas eComStation does not.
Chapter 4: Getting Connected 25
In a segmented network architecture where the eComStation client is
separated from the NT server via a router, NT domain authentication is
impossible with the default configuration of the eCS client. IBM has
described this issue in Technical Document #7775533. IBM Technical
Document #3724433 describes some useful NT administrator tips. In
order for the eCS client to be authenticated by the NT domain controller
the IP address will have to be added to the RFCBCST.LST file.
Other NT resources would be added to the RFCNAMES.LST file. These
files may be updated using MPTS or a text editor may be used. After the
RFC files have been modified, the RFCADDR command can be run from
an OS/2 window which will update the system and prevent the client
from having to be restarted.
Windows: Network Browsing
eComStation clients are unable to browse available resources on
Microsoft Networks due to a LAN Manager parameter called
lmannounce. This parameter defines the response to LAN Manager 2.x
browser broadcasts. The default response is to ignore these
broadcasts. However, the "net view" command can show resources
when the resource is specified as follows: "net view \\resource". If
the command "net view" is used, nothing will show except your
workstation or other OS/2 Servers/Workstations on your network. The
Window's servers and workstations will have to have their default
settings changed as outlined below to enable browsing from OS/2 and
eComStation.
Windows for Work Groups:
The parameter "lmannounce=yes" will have to be added in the [network]
section of the system.ini file.
Windows 95/98/Me:
The parameter "LMAnnounce" is in located in Network settings under
File and Print sharing properties.
Windows NT 4.0 Server:
In Network settings, Services, Server, select the Make Browser
Broadcasts to LAN Manager 2.x clients at the bottom of the dialog page.
Windows NT Workstation (possibly Windows 2000 also)
Users will have to manually modify the Lmannounce entry in the
registry. The entry is as follows:
\HKEY_LOCAL_MACHINES\System\CurrentControlSet\Service
s\LanmanServer\Parameters
