Good Day folks; I just installed WDT 5.1 yesterday & applied all the fixes from the web. I had 4.5.1 installed previously & uninstalled it first (no problems). I thought I would have to re-enter everything in the Comm Console & was happy to find everything stayed (only 2 servers so no big deal). Today (after turning the pc off last night) I got an "undefined server" error when I tried to evoke the editor from green screen seu (this was ok under 4.5.1). When I opened the Comm Console it was completely empty. I have entered the info & ended & restarted the daemon several times but I can't seem to save anything except the server address. The server name always reverts back to the system name & the libl's & other settings aren't saved at all. If I enter the tcpip address for the system name the server name always changes back to OS400A. Am I missing something? (BTW I tried IBM software support.) this is on a HP n5195 laptop(P3 700), Windows 2k sp2, 256M ram, about 9G disk free Tks...Fletch
