We have Autocad Map 4 running on a network with 5 licenses. The network
serves many workstations running window98, windowsNT4, and windows 2000.
Everything had been working quite well untill we had to bring down the
network for another problem and when we brought it back up Autocad would no
longer load giving us the error message FATAL ERROR: Security system
(hardware lock or network license)is not functioning or is improperly
installed. The only thing we had done recently was replace the adesksys.dll
file with the new one which made it possible to run Autocad on a windows2000
Tomorrow we plan to uninstall Autocad from the network and reinstall. The
main question we have at this time is does it have to be installed on the
bootable system disk for a network install. Also if anyone has had a similar
problem and has any sugestions we would appreciate any help we can get.
Thanks in advance.
Does that computer that has AdLM installed on it have a static IP address or
is it assigned by the DHCP server? If you don't have a static IP address on
that server and you were assigned a new IP address when it rebooted then
this would be the cause of your problem and uninstalling then reinstalling
would do you no good. If the IP address on the AdLM server has changed then
the server code has changed and you will have to re-authorize all of your
I intend to live forever-so far, so good.
Don't uninstall/reinstall acad. The problem is a licensing problem. It may
involve you adesksys.dll.
Is this a "network heavy" or thin client install? Is the acad.exe actually
located on the server (and only on the server)?
Are all of the clients unable to get a license or just the non win2k
machines? If you replaced the adesksys.dll on the server the 9x and NT
clients won't work. If you don't replace the adesksys.dll the win2k clients
The way that I got around this (which is most likely completely unsupported
by adesk, but it works, at least for me) was to get everyone out of autocad
(this only happens at about 3:00 a.m. at my office) and copy the complete
acad dir structure to another folder. Example: Our network heavy install
was to a folder on our netware server (fsb_1\vol1\kdisk) called r14. I
copied the entire folder structure to a folder (in the same location) called
acad14. I then replaced the adesksys.dll in the acad14 folder only. I left
all of the NT clients pointed at the r14 folder and I manually change the
win2k clients to point a the acad14 folder. This way all of the "hard maps"
associated with our profiles still work (at \\fsb_1\vol1\kdisk\r14\whatever)
and the new adesksys.dll in the "root" folder is accessed for license
queries (from the win2k machines). The only downside I've seen so far is
that if you modify files in one install you need to be sure to copy them to
The problem that you are experiencing is the adlm server or the adesksys.dll
and not the "acad installation". Go through the stuff in Kevin's previous
post, make sure that the server code on the adlm hasn't changed. Please
don't re-install yet. This is fixable.
