We have 5 NT Servers and 1 HP-UNIX box. 125+ users running Win98 with 3 remote locations using T1 and Frame Relay. When there is a "Hicup" in the Frame or T1 and connection is lost, the users who were conected to an application running on the HP-UNIX box, are then "Blind" to the UNIX box, meaning can't even ping the IP of the UNIX. All of the servers and other workstations can be pinged. Connectivity can be restored by either rebooting the HP-UNIX box or letting it time out (3 hours). Is this problem inherant with UNIX connecting with Win98 and is there a fix for it.
