Hi,
I only got an error when starting Autocad 2009 Mechanical Network Edition.
No other user on the network has a problem.
Inventor 2009 works fine.
Under
C:\ProgramData\Autodesk\NetService\AdskNetSrv.log
I got the following errors:
Error 2012/5/8 10:56:10 Failed to get a PLIST from the server.
Information 2012/5/8 10:56:10 Unable to find PLIST
Error 2012/5/8 10:56:39 Failed to get a PLIST from the server.

Error 2012/5/8 10:58:9 Failed to get a PLIST from the server.
Error 2012/5/8 10:58:39 Failed to get a PLIST from the server.
As I said before no other user working with autocad 2009 has a problem with the network edition.
In the folder is no "AdskNetSrv.DAT" file

The software cannot properly cascade. The debug.log on the server should tell you more. Do you have licenses for Mechanical 2009 and is your license file properly created?
You should have posted this in the network license forum for faster results. I caught this on a generic search.
