That's a windows error code. 1265 means ERROR_DOWNGRADE_DETECTED, the officiale error message being: The system cannot contact a domain controller to service the authentication request. Please try again later. I can reproduce this problem, but not on all machines. It occurs on W10, on 2012R2, on W8.1, but it does not occur on W7 or 2008R2. I found a workaround: The Windows call for changing the password used by the passwd tool is ret = NetUserChangePassowrd (server, username, old_pwd, new_pwd); The server is usually the logon server, prepended by double backslash, as in the variable $LOGONSERVER, and this is how passwd uses the function. However, while this still works fine on W7 and 2008R2, it fails on the newer systems with error 1265, ERROR_DOWNGRADE_DETECTED. The workaround puzzles me slightly, but it seems to do the trick: If I use the domain name (as in $USERDOMAIN) instead of the server name when calling this function, it works as expected, also on W7 or 2008R2. I applied the workaround which will be in passwd of the soon to be released Cygwin 2.6.0.
