New security tool: Web Server Probe
Check out Web Server Probe, a security tool contributed to CodePlex by some Microsoft Security MVPs (including me). From the Web Server Probe CodePlex wiki:
“This is a tool for security researchers. It allows you to search for either an IP address or a DNS name and display all associated domain names known to Bing.
- If a specific IP address is searched, all domain records associated with that address are displayed
- If a DNS name is searched, all domain records associated with all addresses returned for that DNS name are displayed (this case is shown in the screenshot below)
Two separate self-contained versions of the tool are available: command-line-based and GUI-based. The GUI version can be spawned directly from the browser – no installation or additional files are required – just click on the link in Downloads and select Run.
Both versions require the .NET Framework 3.5.”


It throws an exception if you are using a Proxy…
Hmm – in theory, the .NET client classes are supposed to handle that. Can you please try running the command-line version of the tool? It should dump the exception call stack out to the console. Either paste it here or email it to me.
