Very strange:

--8<---------------cut here---------------start------------->8---
19:29:40.987633 tramp-smb-maybe-open-connection (6) # smbclient //win2k/C$ -U 
nicolas -s /dev/null --option client min protocol=NT1
19:29:49.233560 tramp-search-regexp (1) # Quit: "Quit", ""

Try "help" to get a list of possible commands.
^[[?2004hsmb: \>
--8<---------------cut here---------------end--------------->8---

Very strange. There are ANSI ESCAPE sequences prior the "smb: >" prompt,
which are unknown to Tramp. I can reproduce the problem locally.

The appended patch fixes this for me, could you pls test?

Best regards, Michael.
