WCF Accessing Interop.dll Communication Error.

I'm basically moving an asmx to svc and the asmx ismaking a call to the interop dll and all works. On the other hand the wcf service produces a communication error. Is there something I need to do different to get this to work. Thanks in advance...

Error:

"Error Message: System.Runtime.InteropServices.COMException (0xFFFFFFFF): Communications Error Error Code: -1 Mode: Connect ServerAddress: Connected: No Description: Unknown Error: -1 class ATL::CComObject<class CDomains>::Refresh class ATL::CComObject<class CUser>::Login at Stellent.IBPM.Interop.Common.UserClass.Login(Strin g UserName, String Password, Boolean Interactive) at LAS.StellentAPIWrapper.Common.Login(String LoginID, String Password, String ProcessDatabase)
