RFC Error RFCIO_ERROR_SYSERROR in abrfcpic.c : 2105
I am getting the following error when I test RFC connection from XXX to YYY R/3 systems( Windows 4.6 C and kernel 4.6 D - 2297). but I am able to test successfully from YYY to XXX. I verified windows services file and every thing looks correct. RFC Connection XXX to YYY is still working if I use Load balancing(sapmsYYY). This problem started after we reboot the server. Also I am able to connect from every other server except this server.
