SYMPTOMS
After you upgrade from SNA Server 3.0 to 3.0 Service Pack 1 (SP1), TN3270
users who are assigned multiple LUs to their IP address (to support
multiple sessions) are only able to open a single session. This problem
affects TN3270-only clients (not TN3270E).
When attempting to open a second session from the same TN3270 client,
the TN3270 emulator receives the following error:
PROG 505
TN3270E Service Error 511 Telnet negotiation failure: client did not
send a valid configured TN3270 terminal type.
CAUSE
This problem was introduced in SNA Server 3.0 Service Pack 1, by the
addition of TN3270 server support for multiple ports.
STATUS
Microsoft has confirmed this to be a problem in SNA Server version 3.0
Service Pack 1. This problem was corrected in the latest SNA Server version
3.0 U.S. Service Pack. For information on obtaining this Service Pack,
