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?
