  • Computers not Connecting to the Internet

    The machines are Pentium III-1100Mhz, 128 MB Ram, 20 GB Hard Disk!
    Windows XP Profesional with service Pack 2, Office XP with Service Pack 3 installed,McAfee 8.0 is up to date, and Internet Explorer 6

    Problem is that some computers won't connect to the internet when i switch them on, but they ARE connected to the network because they can see other computers on the workgroup!
    After maybe an hour, they'll be connected without me doing anything!

    The last time i had this problem, the forum suggested that i download all the latest service packs and updates. I downloaded them like you suggested and it worked for a while!
    I checked whether there are other programs that have been installed but nothing! I even tried using the Microsoft Malicious Program Removal Tool i found but to no avail

    Any more suggestions will be highly appreciated!!

    How many PCs? Workgroup or Domain?
    How do they connect to the Net, direct, proxy, ICS etc?

      25 Computers!
      Registered on a self-created workgroup(not on the domain)
      They connect to the Internet using Proxy server and i i've checked the proxy settings more than 10 times. IPCONFIG /RENEW worked but...

        Do you have any Firewall appliance like sbox or something like that ?

        check to see if it has a limitation on the amount of the outgoing connections.

        some appliance checks the mac address of the source and count them and if it reaches the limit it blocks the rest of the connections.
        Good Luck

          Ok, teeth pulling time.
          What is the proxy server?
          What does
          IPCONFIG /RENEW worked but...
          mean?
          Any switches involved in this setup?
          Do any of the machines have shares enabled for other machine/users to access?
          Post Ipconfig /all screen capture.
