Client Access Disconnects

[Gary Kuznitz <docfxit@xxxxxxxxx>]

Client Access is disconnecting on a irregular bassis.  I have been putting up
with this for years and would really like to fix it.

1.  It's running XP Pro sp3
Client Access v5r1 with service pack SI11806
OS/400 v4r4 on a 150  (this is the last release a 150 will allow)
No XP firewall
ZoneAlarm is running.
These Ports are open.
23
449
8470-8476
ICMP Echo is allowed in and out

CHGTELNA
     TIMMRKTIMO  40
CHGTCPA
     TCPKEEPALV   120min
SYSVAL
     QINACTITV   *NONE
     QINACTMSGQ  *DSCJOB
     QDSCJOBITV   240min
     QLMTDEVSSN   0
On the PC the WS file has:
[Telnet5250]
KeepAlive=Y
All devises are assigned a name.

I don't want the workstations to time out.
It would be nice if they would re-connect by them selves.  (I've never heard of
anyone acomplishing this.) What happens is the session disconnects. The last 
job
is still active. 2.  I'd like to know how to get the job to cancel on it's own?
I end the job *Immed. The device ends up in a SignOn Display state. 3.  I'd 
like
to know how to make it go to a vary on pending state? I very off the device. I
very it back on to get it to very on pending. I re-connect the workstation.

Thank you,

Gary Kuznitz
