I put together a little script for our roll-out of the new ExchangeDefender platform for our clients. This is put in with addition to any firewall rules on all clients (just in case the firewall is not capable of IP rules that granular). This automatically puts the ExchangeDefender IPs into the allowed list on Exchange 2003. This batch script is released with no warranty and has some basic instructions in the batch script itself (which needs to be modified before being run).

Hope this makes someone else’s life easier as well. The script is available for download here.
