We run a WCF service on a website which we can access with the client exe file from everywhere except on 2 Windows 2003 servers (using Remote Desktop). It gives the following error:
Service channel assignment failed: Could not load type 'System.ServiceModel.HttpBindingBase' from assembly 'System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.*
The RD does run .Net 4 (the target framework) and I can't figure out what else I should do to get it also running on these systems. As written, the very same client using the same service runs fine from e.g. my own Windows 8 PC. What could be wrong?
