Start the iFolder Management tool by entering the following URL in a browser Address field:
https://IP_or_DNS/iFolderServer/Admin
where IP_or_DNS is the IP address or DNS name of your NNLS server.
If your server has a DNS name on your network, the NNLS installation will have used that name when creating the SSL certificate for the server. To avoid certificate mismatch messages, use the DNS name in all access URLs.
Click the Global Settings icon
