Hi

I am getting the following error when attempting to deploy a workflow from the K2 Designer for SharePoint:

Notification Service: Task Error: System.Exception: SourceCode.Hosting.Exceptions.AuthenticationException: Authentication With Server Failed : SEC_E_LOGON_DENIED

Server stack trace:
   at SourceCode.Hosting.Client.BaseAPI.BaseAPIConnection.WindowsAuthentication(SCConnectionStringBuilder connectionStringBuilder)
   at SourceCode.Hosting.Client.BaseAPI.BaseAPIConnection.Authenticate(String connectionString)
   at SourceCode.Hosting.Client.BaseAPI.LocalBaseAPIConnection.OnOpen(SCConnectionStringBuilder connectionStringBuilder)
   at SourceCode.Hosting.Client.BaseAPI.BaseAPIConnectionBroker.OnOpen(SCConnectionStringBuilder connectionStringBuilder)

   at SourceCode.EventBus.EventAdmin.Admin.UpdateCustomEventWithMappings(String connection, CustomEvent customEvent, String user)
   at System.Runtime.Remoting.Messaging.Message.Dispatch(Object target)
   at System.Runtime.Remoting.Messaging.StackBuilderSink.SyncProcessMessage(IMessage msg)

The workflow includes steps that notify users when tasks are assigned to them, and also has Send Email tasks.

Any ideas?

Thanks
Simon
