I tried to register new Windows hardware node by going to OA PCP > Infrastructure > Hardware Nodes > Add New Node > Windows Shared, but the error was shown after I entered IP address/password and clicked Next:
Error: Password should not contain '^'.
The inability to register Windows hardware nodes with '^' in passwords was implemented in scope of POA-76325
Update administrator password on Windows hardware node: it should not contain
^. This symbol cannot be used in command lines with
cmd /c due to limitations of command line parser.
NOTE: in OA 5.4 verification of passwords of Windows AD accounts was done only when registering Windows Shared hardware nodes, since OA 5.5 it has been implemented for all other cases too.
