Administrator node always couldn't reach remote node

dear all...

I install sjsws7 on three solaris 10 machine...

1 act as Administrtion Server an 2 other run Registration Node

registration node success...and I run 1 instance in two node say app1 and app2

but something bother is AS server always say's couldn't reach

app1 and app2...

I check on the app1 and app2 already listen in 8989 port...

if I need to add/modify configuration on I must stop and start the admin-server on the AS server...and then deploy-config or something...

after about 1 minutes the AS server couldn't reach the app1 and app2

so i need stop-start activity to do anything...

admin log always say this:

1. Are you saying that you are able to create/delete/deploy to app1 and app2 for 1 minute after the admin server comes up and after 1 minute it keeps giving the "..unreachable..." error?

2. Could you send me the access and error log of the agents on app1 and app2?

3. Did you access the GUI?
