Persistent Route ignored on XP pro when destination network is unavailable

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance


Hi

I currently have Windows xp Professional workstation(89.2.80.) that
have persistent routes used to connect to a private network(192.168..)
through a gateway lying on the same LAN(89.2...).

I add a persistent route to connect to 192.168.0.1

H:\>route add -p 192.168.0.1 mask 255.255.255.255 89.2.40.135 metric 1

H:\>route print

This works fine till 192.168.0.1 pc is up.
But when 192... is shut down and we try to ping that machine the
gateway The temporary route if changed as shown below.

192.168.0.1 255.255.255.255 89.2.40.135 1

hence forth we are not able to connect to client 192.168...

Does anyone know why it is defaulting to the default gateway when
the persistent route loses connectivity?

Does anyone know how to prevent this default gateway fall back
(registry or network properties setting)?

thanks in advance
