Good morning Tim. I have successfully reproduced the share problem with Trans2SetPathInfo() FileEndOfFileInformation, using smbtorture (RAW-SFILEINFO-END-OF-FILE ) against both Windows 2008 R2 and Windows 7. This, of course, will allow me to dig deeper into the problem.

Interestingly, WordCount/ByteCount truncation against the Dos INVALID_LEVEL error problem (trans2setpathinfo_against_win7_2.pcap) you saw did not reproduce with my clients (who succeeded against the ); the only significant difference I see in the traces you sent and my test traces is that my Win7/R2 targets were using SmbSecuritySignatures (your Win7 client did not).

I have attached my network captures (in both Wireshark tcp dump & Netmon 3.x format).

I will retry with security signatures disabled and get back to you with the results.
