JSI Tip 5612. Event ID 40961, Source LSASRV, can't connect to prisoner.iana.org?

Your event log contains a warning similar to:

I had just set up a new .NET domain controller and allowed it to install DNS, and NAT and the firewall to provide internet access for my clients via the server's DSL Adapter.

I was a little worried, until I realized that the reverse-lookup zone had NOT been configured.

Since the server has an IP address of, I used DNS Manager to configure a reverse-lookup zone with 192.in-addr.arpa, which solved the problem.

NOTE: Unless you manually open some ports, the firewall prevents access to your server from the Internet.
