We have a DTAP environment, the same Tridion versions and hotfixes are installed on all servers. When I try to use Content Porter on the Acceptance or Production environment, I get the following error:
SDL Content Porter 2009 SP2 Could not find SDL Content Porter 2009 SP2 server on SDL Tridion Content Manager server localhost.
On Develop and Test there is no issue.
The Tridion server is 2011 SP1 - 1
