  Workflow web service unable to call another external web service.

  Nov 13, 2009 02:28 PM|LINK

  Hi All,

  I'm trying to invoke an external web service within my Windows Workflow Foundation Workflow Web Service.

  I get the following error message:

  System.ApplicationException: Workflow terminated unexpectedly while processing the current request. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:49868

  Please kindly assist.

  Thank you in advance.

  Best Regards,

  What account is the WorkFlow Foundation Web Service running under? Is it a domain that has acess to get out through the firewall.

  To create a Network Service Account

  • As for creating any account
  • but tick password cannot expire
  • and tick "user cannot change password"
  • Choose a complex password like "A1h4%w£0j5!" and save it in a secure file
  • If a particular group is used for external access, add the user to that group
  • Strictly speaking, interactive logon should be disabled for that account

  You will need to grant explicit permissions for this account.
