Which Version of SNL Server for 2009 SP0 0

SF 2009-02-17

I'm trying to install 2009 onto a cluster of 30 machines but noneof the mahcines will start Solidworks, they all give the error:

Could Not obtain a license file for Solidworks Standard

License Server does not support this version of the feature.
(-25,147,0)

The SNL Server needs updating, please contact your networkadministrator.

Followed by a link to upgrade details.

The problem I have is this, I installed this version of SNL Serverfrom the 2009 DVD. It recognises the License file and even shows ashaving 30 valid licenses.

I am aware I need SNL Server 2009 to run SW 2009, this is why I'vereinstalled it.

Version no is: 17/0.0 (11.4.100.0)

Running on XP Pro 32 bit.

What am I doing wrong?Solidworks Administration
