    Since your pc is brand new I'm assuming your running XP. So use the following settings:

    DefaultReceiveWindow = 192512
    DefaultSendWindow = 16384
    DisableAddressSharing = 1
    InitialLargeBufferCount = 100
    InitialMediumBufferCount = 240
    InitialSmallBufferCount = 320
    LargeBufferSize = 81920
    MaxFastTransmit = 64000
    MediumBufferSize = 15040
    PriorityBoost = 0
    SmallBufferSize = 1280
    TransmitWorker = 32
    FastSendDatagramThreshold = 4096
    EnableFastRouteLookup = 1
    EnablePMTUDiscovery = 1
    IgnorePushBitsOnReceive = 0
    GlobalMaxTcpWindowSize = 64240
    MaxFreeTcbs = 8000
    MaxHashTableSize = 16384
    MaxNormLookupMemory = 5000000
    SackOpts = 1
    SynAttackProtect = 1
    Tcp1323Opts = 0
    TcpLogLevel = 1
    TcpMaxDupAcks = 3
    TcpMaxHalfOpen = 100
    TcpMaxHalfRetried = 80
    TcpRecvSegmentSize = 1460
    TcpSendSegmentSize = 1460
    TcpTimedWaitDelay = 30
    TcpUseRFC1122UrgentPointer = 0
    TcpWindowSize = 64240
    MaxConnectionsPer1_0Server = 20
    MaxConnectionsPerServer = 10
    DefaultTTL = 64
    DisableUserTOSSetting = 0
    TcpMaxDataRetransmissions = 6
    DefaultTOSValue = 92

    VERY IMPORTANT TO DO THE FOLLOWING

    1. Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need.

    2. Open IE and select tools - internet options - connections - LAN settings, make sure NOTHING there is checked.

    3. Make sure you have the latest drivers for your NIC from the manufacturer. Set your NIC duplex mode to 10mb half duplex for Cable, for DSL it is ISP dependent unless you are using a router, if so then set it to 100mb full duplex for both Cable & DSL (the instructions are in my Help & Tips link). If you are using a router make sure you have the latest firmware.

    4. Clear your temporary internet files.

    5. Power cycle your modem, unplug it for atleast 15 seconds.

    6. Download and update then do a scan with SpyBot, anything checked in red is spyware and safe to remove.

    7. Make sure you do the faster web page tweak in my Help & Tips link.

    For W2k try these settings in Cablenut:

    DefaultReceiveWindow = multiply your ISPs download caps in kilobytes by 1024
    DefaultSendWindow = multiply your ISPs upload caps in kilobytes by 1024
    DisableAddressSharing = 1
    InitialLargeBufferCount = 100
    InitialMediumBufferCount = 240
    InitialSmallBufferCount = 320
    LargeBufferSize = 81920
    MaxFastTransmit = 64000
    MediumBufferSize = 15040
    PriorityBoost = 0
    SmallBufferSize = 1280
    TransmitWorker = 32
    FastSendDatagramThreshold = 4096
    EnableFastRouteLookup = 1
    EnablePMTUDiscovery = 1
    IgnorePushBitOnReceives = 0
    GlobalMaxTcpWindowSize = 64240
    MaxFreeTcbs = 8000
    MaxHashTableSize = 16384
    MaxNormLookupMemory = 5000000
