We have a network working with 7 machines (same configuration), NT 4.0,    Sybase System XI and Power Builder 5.0.   Our Sybase was configured with TCP/IP protocol but we had to change  to Named Pipe, because it was causing Windows GPF's in our Power Builder applications.   And what is the problem now?    There are machines that works properly and there are others working slowly, I mean,  the connection with the Sybase.
 When I reboot the slow machine sometimes it returns working slowly and sometimes working properly.

 It would be very thankful if somebody could give me some solution.
