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.

Cause
The default diag-
nostic time set-
ting for the AdLM
is three minutes; it
does not issue li-
censes during this
time.
• AdLM is running but combustion cannot find a
license server.
Cause

lution is not con-
figured.
The system date
and time are in-
correct.
The license server
is in a different
subnet from the
workstation.
Troubleshooting Problems
Solution
This is normal operation. While it is
possible to set the diagnostic time to a
shorter time period, Discreet does not
recommend it.
Solution
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.
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.
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.
