Correct the problem with the VIP server on

For some reason the netscreen can't talk to it.

Copy in the logs you see relating to this, so that we can see what you do.

I would suspect that the VIP is not responding on the port/service that is being forwarded to it.

Double check that.

I've found that the NetScreen will pop that error in the logs ALL THE TIME. I just turn off "Server Detection" in the VIP setup and the alarm goes away. As long as you can do what the VIP is configured to do, don't worry about what the Juniper says.

just append manual to your vip statement via cli to turn off auto server detection

for example

set interface ethernet3 vip untrust xxx "xxx" manual
manual               turn off server auto detection
