0518E

Explanation
Packets sent between the host and the NetWare server
contain signatures to verify the packet originated from the correct
function. If a signature that is received does not match what is expected,
then a communications error has occurred and the connection to the
host will be dropped.

System action
Connection to the host is dropped. The program
on the NetWare server tries to recover from this error.

System programmer response
This problem may occur if the user
on the host is using subchannels for communications and does not use
the LANRES LINK command to change the set of subchannels used for
communications. If the problem persists, contact an IBM® service representative.

User response
The user on the host should enter a EWXCONN LINK
command to establish a new connection with the NetWare server.
