I can not connect to teradata database: "Connection reset by peer"

I installed DEMO databases, but I can not connect to It. I recieve message "10054 WSA E ConnReset: Connection reset by peer". I read that need to change Registry key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems\Windows" parameter "Shared section=1024,3052,512" to "Shared section=1024,3052,128". But it did not solve problem.
I tried to execute samples programm from DEMO istallation.
What must I do to connect to DEMO database?
