The Network License Manager works with any versions?

[vinicius.andrade]

I installed the Network License Manager in a Windows 2008 Server ( I installed the
NLM (LMTools) using the CD of AutoCAD 2013). The AutoCAD 2013 works fine in the client
machines, but the 2011 and 2012 version don´t. In the page of Autodesk, on Manage
Serial Numbers, I can see the Serial Number for 2011, 2012 and 2013 Suites. Why the
AutoCAD 2011/2012 don´t work in the client machines? Note: in the 2011/2012 version
appears the message " A valid license could not be obtained by the network license
manager. If you are still unable to access a license, contact your system
administrator. Error [-96.7.11001] ".

first verify the contents of the license file

Darren is right on.  Does your license file actually include the Subscription PACKAGE license or is it only for 2013?  The link above will help you determine that easily.
