Since moving over to the new online help system the old Vault Thin Client help is not redirecting correctly.
To fix this problem please open the Help_Information.htm file located in the C:\Program Files\Autodesk\ADMS Professional 2014\Server\Web\WebClient\VaultHelp directory.
Edit line 10 from: redirURL = "http://wikihelp.autodesk.com/wikihelp-vault-webclienthelp-2014-enu";
To: redirURL = "http://www.autodesk.com/wikihelp-vault-webclienthelp-2014-enu";
This should fix the help redirection.
