Make sure that in your DNS records
redirects to the fully qualified domain name
instead of just the hostname of your K1000.
Alternatively, delete the CNAME record and create a new host A static record for kace.
If this happens only with Firefox and no other browser try clearing your cookies.
If redirect still happens, see:
Have SSL configured? The server may be trying to switch from http to https for a page.
For troubleshooting purposes, login to console with username/password netdiag/netdiag and issue command httpd80.
Are you using https://your.server.url/admin in your browser or http://your.server.url/admin?
Make note of the results and notify your Kace Support Engineer.
