fiddler2 comes close but this only deals with web browsers it seems.

I need this tool to debug why I can't mount a common standard network/NAS drive (e.g. via SMB/SAMBA) in Windows 7 Pro and Home.

Looking for definitive answer to accessing a network drive/NAS/SMB drive via Windows 7 HOME and Windows 7 Professional. Is it possible and how?

You mean Wireshark? –  Daniel Beck Jul 9 '11 at 11:09
    
+1 @Daniel Beck That would be the answer. I guess it can be used for wired as well as wireless connections. I would use it to compare the sequence of packets exchanged on successfully connecting the NAS to XP, with those of the unsuccessful attempt to connect with Windows 7. Does the too provide facilities to compare 'recorded' packets in this way? If you make it an answer, I will likely accept it, after leaving the question open a little longer to give others a chance to contribute. –  therobyouknow Jul 9 '11 at 12:29

Wireshark is pretty extensive and useful for this. A more geeky low level tool (that I prefer, but then I'm a bit old school) is windump winpcap.org/windump. This very much a tcpdump for windows. –  Drav Sloan Jul 9 '11 at 13:12
    
+1 @Drav Sloan for that other option. Thanks. –  therobyouknow Jul 9 '11 at 16:48
    
Reporting back, so far I can see that the working (i.e. the one that can read the files in the drive) Windows 7 that does mount (home) uses a variable $IPC in the samba messages a lot more than the non-Working windows 7 professional. It's not significant that home works and not professional. They should both work but I think it is some other factor. That's as far as I can ascertain at the moment. I'm not a SAMBA expert so can't deduce much at the moment. But mysteriously the Windows 7 professional began working after a windows update yesterday evening and after some tweaks i tried. –  therobyouknow Jul 15 '11 at 14:21

Use the Wireshark packet analyzer. It has special support for many protocols and can help you with debugging issues by decoding SMB messages.

+1 accepted answer. I will report back -- if it helps me find the root cause of my unsuccessful mapping network drive in windows 7. –  therobyouknow Jul 9 '11 at 16:48
    
reported back in question above, as promised. –  therobyouknow Jul 15 '11 at 14:27
