5250 and 3270 Applets Do Not Find SNA Server

• Microsoft SNA Server, versions 2.11 (all SP), 3.0 (all SP), 4.0, 4.0 SP1, 4.0 SP2, 4.0 SP3
  on the following platforms: Win95, Win98

SYMPTOMS

On Windows 95/98 computers, the 5250 and 3270 applets may not find the SNA Server when the SNA client configuration is set to Local mode (locate servers by SNA Sub-domain). A TCP/IP error 121 may also occur.

CAUSE

Local client mode (TCP_IP transport) is unreliable on a busy network because the client does not wait long enough for SNA Servers to respond to its sponsor request broadcast.

WORKAROUND

Set the SNA client configuration to Remote mode (locate SNA Servers by name) and enter the sponsor server name (or IP address).

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.
