VB applet that create event logs on Windows 2000 servers

Recently I've been working on a monitoring solution so I need a tool that can generate event logs to trigger the monitoring agent. There are a few tools from MS Support Tools or Resource Kit Tools that can do this but they all have some limitations. For example, some can create logs for existing sources, the other can't create log for existing source/ID.

Blackhole routers and how they affect your AD environment

Recently I've been working on a Kerberos authentication issue with servers that connect to DCs via VPN. The servers can join domain fine, users can log into domain from these servers, and browsing domain resources seem no problem. However, for a particular application, it always fails to get the AS ticket from DC.
