I have a VB.Net app I'm working on that will run fine in and out of the
IDE on the Development workstation however when I try and run it on
another workstation I get this error.

Unhandled Exception: System.Runtime.InteropServices.COMException
(0x80004005): Login unsuccessful
at System.RuntimeType.ForwardCallToInvokeMember(Strin g memberName,
BindingFlags flags, Object target, Int32[] aWrapperTypes, MessageData&
msgData) at GroupwareTypeLibrary.DIGWSession6.MultiLogin(Strin g
vUserID, Object vCommandLine, Object vPassword, Object vWhenToPrompt,
Object vReserved) at AddressBookManager.Module1.Main()

Other than having VS 2005 on it the workstations are the same.
