Samba 2.0.5b on Linux 2.0.36. Innoculan virus scanner up-to-date on WinNT4SP3HU and WinNT4SP5HU. On access virus scan has been enabled on all files. (OK, I guess it shouldn't, but it works more- than-less with NT servers). There are zillions of problems (eg. oplock breaks (oplock is now disabled); the client and server having different ideas of what files are open; multiple connections from the same client; losing connection on the middle of reading/writing files; etc.). Some of these problems I can reproduce. I can send smbdumps to whoever would be so kind as to investigate this problem. When opening whatever.hlp with winhlp32, the user gets a read error message after scrolling down. Some mystical (for me) events happen: The client sends SMBtrans2 with file=whatever.tmp.in2 and whatever.gid.in2. These get answered as SMBError = ERRDOS - ERRbadfile (File not found.) That's right. Then the client sends SMBntcreateX "whatever.gid" with the same tree id, and it gets "SMBError = ERRSRV - ERRinvnid (The tree ID (TID) specified in a command was invalid.)" I don't see why it became invalid. :( Some packages later the client gets "SMBError = ERRSRV - ERRbadpw (Bad password - name/password pair in a Tree Connect or Session Setup are invalid.)"
