Case: VPN works on one computer but other one

This is a good case. It doesn't work for you because you are using the same IP range as the VPN. These search results may help,

Can someone tell me how I can begin to troubleshoot this problem? Both
my colleague and I are connected to the same VPN. There is a server
within this configuration with local (private) IP 192.168.0.60. My
colleague can ping the server fine, but I cannot (my requests
repeatedly time out) although my Internet is otherwise working
normally. This is what I get when I run "ipconfig" from cmd:

Ethernet Adapter Local Area Connection:

Connection-specific DNS Suffix: : abcd.co.comcast.net
IP Address: : 192.168.0.100
Subnet Mask: : 255.255.255.0
Default Gateway: : 192.168.0.1

Ethernet Adapter Wireless Network Connection:

Media State : Media
disconnected

PPP Adapter (what I named VPN network):

Connection-specific DNS Suffix: :
IP Address: : 192.168.0.121
Subnet Mask: : 255.255.255.255
Default Gateway: : 192.168.0.121


This is my colleague's ipconfig output while connected to the same VPN:

Ethernet Adapter Local Area Connection:

Media State : Media
disconnected

Ethernet Adapter Wireless Network Connection:

Connection-specific DNS Suffix: : austin.rr.com
IP Address: : 192.168.15.104
Subnet Mask: : 255.255.255.0
Default Gateway: : 192.168.15.1


PPP Adapter (what she named VPN network):

Connection-specific DNS Suffix: :
IP Address: : 192.168.0.152
Subnet Mask: : 255.255.255.255
Default Gateway: : 192.168.0.152


Thanks for any advice, - Dave

Hello,

I have LAN A and LAN B. From computer A I can ping computer B with computer
name but when I use Search option or \\computername, it doesn't find it.
What could be the issue?

Thanks

Do you have WINS ?

Yes, WINS, DNS & DHCP.
Its XP firewall issue. Turned it off. Working good.
