Microsoft Internet Connection Sharing
Uninstall MS ICS before the installation, remove TCP/IP protocol, restart and bring it back.
Active Directory
WinRoute may co-exist on a system configured as a domain controller, however Active Directory requires DNS service. This means that the DNS forwarder in WinRoute must be disabled. Functionality such as DNS cache, local DNS using the host file, and demand dial for DNS queries will not work.
Anti-Virus
Some Anti-Virus programs act as a mail server by binding to common mail ports such as 25 for simple mail transfer or 110 for POP. If you would like to run anti-virus software on the WinRoute computer you must change the ports that WinRoute uses. This is done in the advanced settings of the mail server.
Proxy Client software issues
Some proxy servers require software to be installed on all client machines. This client software makes all applications query a proxy server. If the client proxy software is not removed, that machine may not be connected to the internet because WinRoute is not setup as a proxy server.
Network Card driver issues
Try to use the most standard network interface cards. If you have a special, old or brand new card in your computer, its driver may include specific instructions that will prevent WinRoute from communication with it. Try to find the most standard Ethernet card in your network and simply exchange their position. Quite a few originally "unhappy" customers turned to "happy " customers just by changing the card or updating the driver.
WinRoute is a fully neutral software router/firewall that does not require any client software running on client computers unless remote administration is used in which case a client or external machine must install WinRoute Administration "wradmin.exe".
