We have corrected the issue. There was something wrong with the files in the WebCache Folder.
When starting Web Cache we get the following message:
An error occurred while starting "Web Cache".
WebCache : WebCache - failed to start a managed process after the maximum retry limit
WebCache : WebCacheAdmin - failed to start a managed process after the maximum retry limit

When we open the event_log in the \webcache\logs folder, there is nothing there. The process is not writing any type of message to the event_log.
We have tried changing port numbers without any success.
This process was working until a restart of the server yesterday. Now Web Cache and Portal are not showing active.
