I have been wanting to get the use of dig on Windows 7 for awhile but hadn’t taken the time to do so until now. The problem is nslookup is not as helpful in terms of TTL of zone files, etc. and while you can accomplish your tasks with nslookup using dig makes life much easier on Windows 7 when troubleshooting DNS type issues. The other night I was in the middle of a time critical launch of a new web cluster and needed dig on the Windows 7 laptop I was working on so I decided to get it working while I was waiting for some data to transfer. I actually had slipped on setting the TTL, which was for a single sub domain that was part of the transfer, from a TTL of a entire day (86400 seconds) to a TTL of one hour (3600 seconds). Anyhow below is more information on installing dig on a Windows 7 computer.
Typically when I need to use tshark I do so on a Linux server however there are times where it is convenient to have tshark available on my Windows 7 laptop. The TShark application is installed with Wireshark so installing TShark is very easy using the Wireshark GUI intsaller on Windows. One thing that makes tshark more useful is adding the tshark.exe executable to your PATH on Windows so you can open a command prompt and use TShark from any directory. Follow the directions below to first install Wireshark and then to add the directory that includes tshark.exe to your Windows 7 PATH.
My Windows XP laptop during boot used to automatically log on my primary user. At some point either during a Windows XP security update or after installing an application that changed and I was taken to a Windows XP splash screen and required to click on my user to log in. An example of what the Windows XP log in splash screen looks like is below.
Modifying a users PATH variable in Windows Vista is easy. You may want to modify the PATH for a user if you have an executable located in a directory that is not already in the default Path. One example of this is if you install cygwin to have Unix/Linux style commands on Windows you would want to add C:\cygwin\bin to your user Path variable.
Follow the directions below to modify the user Path system variable:
