We are getting a semaphore timeout when trying to join any Windows 8.1 computer to a Windows 2003 domain. The interesting clue is in the sniffer trace. The Windows 8.1 computer tries to negotiate an SMB2 protocol request over port 445 on the domain controller, and the domain controller never replies to that request.
Does anyone have an idea what might be going on here? I gather a Windows 2003 DC would not implement SMB2?
I find instructions for turning off SMB2 on the *server* for Windows 8.1, but I have no idea how to affect the behavior of the Windows 8.1 client to just use SMB1 instead of SMB2?
On the Windows 2003 DC, is there anything we can do to get it to negotiate this request properly?
