In line with this post: http://www.hugheserblog.com/2012/05/22/error-creating-iis-smtp-virtual-servers/ I am receiving the same issues:
When we tried to add more than 4 IIS SMTP virtual servers, we got the error within IIS, “The system cannot find the path specified.”
This post is almost 2 years old and my server is up to date with Windows updates so I assumed it would be fixed already.
Does anyone know if I need to do something special (ie. contact Microsoft) to get a special fix for this? The information in the post suggests it should have been included in an update.
