5250 Emulator Won't Connect Even Though Sessions Are AvailableLast reviewed: March 19, 1998Article ID: Q166875 |
The information in this article applies to:
SYMPTOMSWhen connecting to an AS/400, the 5250 applet shows Not Connected in the lower left corner. SNA Server shows that there are sessions available for the LU-LU pair the 5250 applet is attempting to use. However, some of these LUs on the AS/400 are in an Active - Detached state, thereby preventing the request for conversation from succeeding. The same thing will happen with other 5250 emulators. However, the message displayed in the emulator may be different. NOTE: There are various situations in which you might see a Not Connected 5250 status. This article documents one possible situation. For other possible situations, see the following Microsoft Knowledge Base article:
Article ID: Q150796 Title : 5250 Emulator Displays a BlackScreen Then DisconnectsCAUSE The exact cause of why the AS/400 sometimes shows sessions in an Active - Detached state is unknown.

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them.
