Cannot Ping Laptop on network

Posted on 2006-03-30

I cannot ping a laptop on the network or do any remote administration to it. The laptop operates normally for any user of the machine. You can see and access any network resource. This laptop is windows 2000 professional and does not have any installed firewall other than Black Ice which is set to manual and not in a started state. Any suggestions?

    1. Are u able to ping any server from that laptop?
    2. What do u get when you type ipconfig? Is the IP valid?
    3. What is the subnet mask? Is it the same as the others?
    4. Are u using dynamic or static IP?

    1. I can ping any server or workstation from the laptop
    2. The IP is valid with the propper subnet and gateway. I have moved the laptop to other vlans and switches with the same result
    3. the subnet information is correct
    4. Dynamic IP

    Like I said I moved the laptop to various locations to remove the switch or port from beiang a problem. The machine recieves a new IP at each location without any issue. This seems to be an inbound only problem.

    Found the issue. It was a corrupt Cisco VPN client service. Thank you for your time.

    Seems like you're not using standard private IP range, anyway if you have found your problem then go ahead to close this. Cheers.

    Private IP range
    For Class A network, - (10/8 prefix) range (For big network that requires a huge pool of 16 million private IP addresses)

    For Class B network, - (172.16/12 prefix) range (For medium-sized network that requires 65000 private IP addresses)

    For Class C network, - (192.168/16 prefix) range (Commonly used IP range on smaller network for easier addressing of 254 IP addresses. May not necessarily be smaller network but network managed in smaller blocks.)
