IIS 7.5 FTP Service User UserGroups for Authorisation

view full story

http://serverfault.com – i have a W2K8 R2 with the IIS FTP Service and a local windows user group (ftpusers). In addition to this i have several Windows Accounts, which all only belong to the ftpusers group. The FTP Server is configured to allow the ftpusers to access the server (with isolated root for each user). Whenever i add an user to the ftpusers groups the ftp server does not recognize, that the user is allowed to use the site. I have to do a iisreset to force the ftpserver to reload the user database. now my Question: Is there any way to force the ftpserver to update the user/roles without restarting the wh (HowTos)
