Hi,
I am deploying a Metaframe environment with 90 win-term
( Compaq of various models ).
There are 4 servers in 1 server farm windows 2000-SP2, Metaframe XPe 1.0 sp2.
(the FR2 has not been activated becouse keys
come separately from connections and base product
keys: their delivery are on late, and I will activate asap).
The Applications
----------------
The software installed on the servers is minimal:
for now, just a terminal emulation for Unix application
server with character interface; in next months, when people
will be trained, we will install some Office applications).
The Architecture
----------------
All is going well (it is not difficult, done by the minimal
features offered) but the mission is critical: the terminal
are a lot and are in a public administration office, many
of them are desktop information .
For this motivation the customer has chosen 4 servers
in load-balancing architecture.
The EDP manager has decided to publish the entire desktop
and I have created just 1 published application (the desktop) called RACK ( the servers are named RACK1 to RACK4 ).
The Problem
-----------
The win-terminal have fixed ip-address, but when they go to discover Citrix Servers the have some problems:
- Using HTTP+TCP, they don't see any servers.
- Using only TCP, they see the servers and the applications, but sometimes they fail to do this;
when the terminal is configured, 4 times on 5, they dont find the server: when the connection is done, all goes well.
- If I write explicitly the ip address of the server, all goes well without problems. I can divide terminals in the 4 servers, but I cannot use load-balancing, and automatic failover in case of 1 server crash.
Notes:
1) the customer has a big net, with a 255.0.0.0 class.
2) The servers and the terminals are on the same hubs
(some linked by fibres, but there are not firewall or
routers between them) .
3) The IP of terminal is Fixed, WINS and DNS point to
the 2 Windows2000 domain controllers, the defgtway
is a router, but we dont need of it.
4) In another Server (alone) at the same customer,
we have deployed a Metaframe environment with Office
faetures: also in this case, with other Compaq
terminals had the same problem. Going in
Citrix Management Console / Server Farm / Properties /
Metaframe Setting tab, I check the
"Data collectors respond to ICA Client broadcast...",
Metaframe says that if it will discover MetaFrame 1.8
server, it will turn off this feature,
I know that there are not MF1.8, push OK.
All goes well, clients find server by broadcast,
but in few days the server turn off this feature,
as finds metaframe 1.8 Server.
Going in Events of server, we see strange message as:
Computer JOHN belives to be master browser... ;
we have no control to this machines:
it is in the same network (there are a lot of
computers in a lot of workgroups, self installed by
user: a total anarchy but nobody can avoid this,
for now; the choice of Citrix is due also by this).
5) The customer does not want use broswers, NFuse or
other "Strange" solutions: He wants that the
user "belives" to have a computer in front of him.
Have anybody had similar problems, about automatic disc.,
class A net, master browser, or a workaround solution
to give however high reliability to the system ?
thanks in advance .
