Alright gang, OT because it's not a pure Cisco question... I use a sniffer everyday & I am looking for a good book(s) to assist in analyzing CIFS/SMB network traffic. I am looking for something that would help me be able to more effectively troubleshoot/UNDERSTAND the following (for example): SMB: R transact2 - NT error, System, Error, Code = (52) STATUS_OBJECT_NAME_NOT_FOUND OBVIOUSLY, the object was not found...but what is an "R transact2" ...and then there are things like: SMB: R NT create & X, FID = 0x6002 So I am looking for a detailed book on SMB... I did the usual search engines, but I wanted to know what my fellow guru's use/recommend. TIA!
