Question : how to delete route in xp

have tried to use the route delete command to remove the routes in xp. However it seems unsuccessful.
The following is the route table in my pc.

Active Routes:
Network Destination        Netmask          Gateway       Interface                 Metric
          0.0.0.0                   0.0.0.0              192.168.0.1   192.168.0.103         25
        127.0.0.0                     255.0.0.0        127.0.0.1       127.0.0.1                 1
      169.254.0.0          255.255.0.0      169.254.241.150  169.254.241.150      30
  169.254.241.150  255.255.255.255        127.0.0.1         127.0.0.1                30
  169.254.255.255  255.255.255.255  169.254.241.150  169.254.241.150      30
      192.168.0.0    255.255.255.0        192.168.0.103   192.168.0.103             25
    192.168.0.103  255.255.255.255        127.0.0.1       127.0.0.1                  25
    192.168.0.255  255.255.255.255    192.168.0.103   192.168.0.103           25
        224.0.0.0        240.0.0.0  169.254.241.150  169.254.241.150                 30
        224.0.0.0        240.0.0.0    192.168.0.103   192.168.0.103                   25

  255.255.255.255  255.255.255.255  169.254.241.150  169.254.241.150      1
  255.255.255.255  255.255.255.255    192.168.0.103   192.168.0.103       1
Default Gateway:       192.168.0.1
===========================================================================
Persistent Routes:
  None

When I try to delete the route , e.g.

route delete 192.168.0.0 mask 255.255.255.0 192.168.0.103

it always prompts the error "The route specified was not found."

I have no such problem in winme. It's only happened in win xp.
As I will have the VPN connection, after connected to VPN, all the internal network connection or internet connection can't be accessed. I will use the route command to make the active route in winme before. However it's unsuccesful in winxp. Would someone help pls?
P.S. I am using Nortel VPN Client for the vpn connection. After connected, I want to delete some routes to make the internal network working, but it seems unsuccessful.

Answer : how to delete route in xp

I think I have found the solution..

It seems the bug in winxp. Now I want to change my question, and will give the same point to the solution provider.

After connecting to the vpn, I can route add or route delete to change the route table to access my local networking. As  the vpn gateway is dynamic,  I need to type in the route add or route delete command manually after every login the vpn. e.g. if this time the vpn gateway is 10.0.0.1 ,  I need to type the command , route add 10.0.0.0 mask 255.0.0.0 10.0.0.1 manually .If the gateway is static, I can write a batch to do so.  Is there any method I can add or delete the route related to the vpn gateway automaically?

thx
