We have LDD r2 with network licensing in our office. Users under Windows
2000 lose their license after repeated uses in the LDD menu. It lets them
work for a while (using the ldd commands) and
then it says that the network license has been lost. The only remedy for
this so far is to restart acad and work again until the license is dropped
which happens as frequently as every five minutes depending on the commands
We have the environment variable set up properly in Windows 2000 and
also have updated the adesksys.dll files on all of the machines with the
problem. This does not happen under NT or 98, only 2000.
Anyone have any ideas?

I posted a similar problem in the LDD group a month ago. Here is the post:
Here is the scene:
A user on a NT 4.0 machine(network Lic install; same server) will run Land Dev R2 with Civil R2 loaded. The user will use the Grading
Wizard to create a grade object. The user then will use the ZE macro to zoom out. BAM, a dialog box declaring
"Licence Server is Down" appeares. The only option is to ok. You have to ok twice before you can get back to CAD.
This will occure right away, or the user will repeat the grading wizard several times before crashing,and
it will only crash with Civil/LDD commands. When we monitor the licence log it seems to drop the Civil Lic.
But the user can sometimes continue to use civil commands, only with the Licence Server is down box coming up
between commands. When we use the same licence server and client install to a new machine we can not crash it. Turns out the
machines that are crashing are only Intergraph machines. Until today. An older Compaq started having the same problem. It almost
seems to be a hardware issue with older machines. We have made sure our NIC card drivers are updated on the older machines.
Any ideas? How can we track down a strange hardware issue like this? Anyone else get this before?
We have been working with AutoDesk to find a solution but have had little luck there. But we think we have tracked it down to hardware issue.
When we had this problem every machine was a Dual P2 system. We had a tech guy pull a processor and the problem did not happen again.
So the question is, is this a Dual Processor machine?
I think we have found a solution . . . the machines that have dual
processors need to have acad.exe set to processor affinity (only works for
win2000). You set affinity by going to the task manager - processes -
acad.exe and right clicking. Go to processor affinity and uncheck one of
the processors. To permanently set affinity go to
or copy the two files that I am attaching to a floppy disk and run the batch
file on each machine that has the problem.
The batch file basically copies the Imagecfg.exe file to the c:\ and runs
the command line to set affinity. If your acad.exe is in another directory
other than c:\acadldd2 then you need to edit the batch file accordingly. So
far it seems to be helping and this way you dont have to pull processors.
