Network Monitor 3.4 - Interop Why read the Open Protocol Specifications when Network Monitor can do the first pass for you? These two built in Standard Filters can help find problems with SMB implementations 12

Network Monitor 3.4 - Interop How can I locate documentation based on a trace I m looking at? These two options jump to the NPL Parser source code. Look at the top of the file for Open Specification References 13

Conformance Testing 1. Start with Spec Conformance Implementation responds only with what the Test expects Specification Conformance Error Implementation does the unexpected (discrepancy) Test 3. Write Tests to check Conformance Implementation 2. Create Implementation from Spec 15

Conformance Testing Specification 1. Start with Spec Failure of conformance indicates either the Specification, Implementation, or Test is Incorrect. Test 3. Write Tests to check Conformance Implementation 2. Create Implementation from Spec 16
