whois like functionality on Windows?

[Gerrit Muller]

I am migrating a website from a UNIX based machine to an Windows 
machine. In the logfiles I got from the old machine I mostly got domain 
names and sometimes only IP addresses. The Windows machine seems to 
produce only IP addresses.

Somehow I cannot find a windows solution to translate an IP address back 
into a domain-name. Searching with Google shows that more people have 
been wrestling with this problem.

I did find working whois scripts, but unfortunately:
- the verbose whois registrar information often forbids automated access
- the information is rather distributed, so you have to somehow access 
sufficient servers
- you still have to find the domain name in the sea of details returned

I also found socket based solutions, but these solutions crash with the 
message "host not found" :-(

Anyone suggestions?

kind regards, Gerrit
