Tools to package with distributable for easy debugging?

Question

We are looking for a set of free Windows tools that can be put in a "tools" directory and distributed with our applications, so that when we encounter an issue on a customer site we can diagnose it without having to copy the log files over to another machine.

Here's what we've come up with so far:

1. Notepad++
2. BareGrep
3. BareTail
4. WinMerge
5. List item
6. Putty
7. WinScp

Do you have any other suggestions, or substitutes for those Apps. Ideally we want appas that just run without any installation.

Answer 1

I would suggest adding:

• 7-zip
• Wireshark
• System Explorer

Answer 2

• RedGate Reflector or ildasm - for searching for errors basing on stack trace;
• (g)awk (great for querying logfiles);
• LinqPad or QueryExpress if you work with DB;
