BizTalk Error: Unable to serialize web directory

When trying to export an MSI from BizTalk Admin Console for an application, I got this error:

“Unable to serialize web directory… Verify the location exists and it is accessible”

Example of error in BizTalk Admin Console

In my case, we had SharePoint on the same machine as BizTalk, and thus a coworker set up a special virtual directory for published BizTalk services, and assigned port 9000. Thus, when I ran the wizard to create the webservice, I had to specify port 9000, and now on the export MSI file, I also need to specify the port 9000 (following a colon after the localhost name).
