When testing the Pharos EDI Server this error occurs:
Error: A string literal was expected, but no opening quote character was found.
Line: 20
Server Error in '/
Initialize Session Failed
This has been traced back to a problem with System.EnterpriseServices.dll.
There is an issue with the .Net framework that can cause the installation to mess up if the Distributed Transaction Coordinator service is in a bad state.
To resolve:
Disable and stop that service
Reinstall the .Net 2.0 framework
Restart, and see if you still get the error?
Once the problem is resolved, you should be able to re-enable the DTC service without impact (but test the EDI again to be sure).
