Pipe character in FTP account user names in Expression Web 2

If you are updating web sites with Expression Web 2 that run on a virtualized Windows Server 2008/IIS 7.0 systems. On these systems, it is possible to create FTP account names (usernames) which contain the pipe character |. Unfortunately, Expression Web 2 (EW2) gets confused with this character, and won't allow you to connect.

On IIS.NET, there's a description of the problem on a blog post. It suggests changing IIS settings with the "useDomainNameAsHostName" option in applicationhost.config. This option is available starting with FTP 7.5 extension to IIS.

If you cannot get to this config file (your hosting provider might not let you change it), then the other workaround is to add another FTP user account, which doesn't contain the pipe character in the username.

Finally, this problem should be fixes in forth-coming Expression Web 3.
