	IE Timeout Tuner License: Freeware
	This tool can adjust 3 "hidden" registry settings of Internet Explorer to control caching of DNS records, server connection timeout, and caching of server information. It can be useful to change these settings to very low values, especially when testing web-servers with quickly changing DNS records / IP addresses. For example in DNS Round Robin or Simple Failover setups. Internet Explorer does not honor and does not use the TTL (time to live) value provided in DNS records. Instead it caches all DNS records for a fixed period of time (as per this setting) - with one exception: After Internet Explorer has fetched a web-page, it does not immediately close the TCP connection to the web-server. By keeping the connection open, following requests to the same web-server can be executed faster. This is known as "keep alive". This setting affects both DNS caching and server connections ("keep alive") timeouts. Internet Explorer does not refresh DNS records if another page is requested from the same server domain name within this time interval - even if the DNS Cache Timeout setting has a lower value. In other words, DNS records timeout according to the higher value of this and the DNS Cache Timeout setting. However, server connections appear to timeout according to the lower value of this and the Keep Alive Timeout setting. So for the most predictable results, the value of this setting should be set lower than or equal to the DNS Cache Timeout setting, and higher than or equal to the Keep Alive Timeout setting.

	TSIG Key Generator License: Freeware
	This tool can generate a TSIG key value (base64) for you very easily. The key value complies with RFC2845. Secret Key Transaction Authentication for DNS (TSIG) is a secure method of authenticating clients making dynamic DNS update requests. The client application and the DNS server share a secret key value which is used to sign (HMAC-MD5) each update request. You can think of the key name as a user ID, and the key value as a password. You can create a key value using four different methods: Random 128 bit value, random 256 bit value, random 512 bit value or from pass-phrase (MD5-hash). The key value generation functionality of TSIG Key Generator is already built into Simple DNS Plus and Simple Failover from JH Software.
