StraceNT is a System Call Tracer for Windows. It provides similar functionality as of strace on Linux. It can trace all the calls made by a process to the imported functions from a DLL. StraceNT can be very useful in debugging and analyzing the internal working of a program.

StraceNT uses IAT patching technique to trace function calls, which is quite reliable and very efficient way for tracing. It also supports filtering based on DLL name and function name and gives you a lot of control on which calls to trace and helps you to easily isolate a problem.

StraceNT is open source softwaer available under the BSD license at github.

The implementation details of StraceNT are available in the following article: StraceNT.pdf.
