Troubleshooting Problems

Configure TCP/IP before proceeding, then follow
the steps in
Configuring the FLEXlm Server .
The AdLM runs diagnostics and then goes online.
The diagnostics may take as long as three minutes to
run. When the network version of
combustion is
started on a workstation, combustion responds by
first sending a broadcast to the local network
segment to look for a license server with a free
combustion license. If a license server is found, a
license is checked out from the server, and
combustion will start on the workstation. If a
license server resides in a different network segment
from the workstation, the license server will not be
found unless the ACADSERVER environment
variable is set to include the license server’s
hostname on each
combustion workstation. A
workstation may be restricted to pulling licenses
from specific license servers by the prefix symbol @
to the hostname listed in the ACADSERVER value.
Using the @ symbol effectively disables the
broadcast method of finding a license server.
Following are potential problems that can occur and
their solutions:
• The License Manager Service does not start.
• AdLM will not issue licenses for three minutes after
startup.
• AdLM is running but combustion cannot find a
license server.
Cause Solution
The AdLM is run
on the wrong
platform. The AdLM requires Windows 2000 or
Windows NT running on an AMD or
Intel-compatible processor running
300 MHz or higher.
Microsoft TCP/IP
is not installed or
is improperly
configured. The AdLM requires TCP/IP to operate.
Verify the TCP/IP configuration by
using the PING command at a DOS
command prompt.
The AdLM was not
launched from
the Start/ Stop/
Reread panel of
lmtools.exe. Start lmtools.exe, go to the Start/Stop/
Reread tab, and press “Start server”.
Cause Solution
The default diag-
nostic time set-
ting for the AdLM
is three minutes; it
does not issue li-
censes during this
time. This is normal operation. While it is
possible to set the diagnostic time to a
shorter time period, Discreet does not
recommend it.
Cause Solution
TCP/IP name reso-
lution is not con-
figured. Try using the PING command at a DOS
prompt. The syntax of the PING
command is ping <hostname>. If you
cannot successfully "ping" the license
server from a
combustion workstation
and "ping" the workstation from the
license server, the AdLM will not work.
Name resolution may be accomplished
in a variety of ways on a Microsoft TCP/
IP network. The simplest method to
provide name resolution is to create a
hosts file with entries for all
workstations on the network, and copy
it to the \winnt\system32\drivers\etc
folder on Windows 2000 and NT
systems. Windows 2000 and Windows
NT come with a sample hosts file
located in the proper destination folder
for that operating system.
The system date
and time are in-
correct. Verify that the date and time are correct
on all workstations, and that they are
synchronized with the AdLM station.
The AdLM will not issue a license to a
workstation that has an invalid date.
The license server
is in a different
subnet from the
workstation. Set the ACADSERVER environment vari-
able value to contain the hostname of
the license server so that
combustion
can connect to a license server on
another subnet. To set ACADSERVER to
multiple license servers, separate each
hostname with a semicolon. Consult
your operating system documentation
on how to properly set an environment
variable. The value of an environment
variable can be confirmed by typing set
|more at a DOS command prompt.
