Correct, http.admin.ssl.enable is on as well.
One of our filers is running 8.0.4 7-Mode and the others are running 8.1.2P1 7-Mode.
Also, all of our filers have the same options http set as we have been discussing so far.
I have also attempted to create a local user on the filer with administrative rights and tried to use this user in Balace and recieve the same results. In the Balance installation guide, it informs us to ensure that ports 9443 and 443 are allowed for inbound and outbound traffic from the Balance Proxy server. When I tested these ports with telnet, I get that the connect failed. On the Balance proxy server, I have tried with Windows firewall disabled, and with creating rules to allow these ports for inbound and outbound traffic. Needless to say, this didn't get me anywhere. The guide also notes that UAC must be disabled on the Balance Proxy server, which it is in fact disabled. Just thought I would add that in there as well.
Thank you for the quick responces by the way!
