Vista 64 Network Performance issues.

    I am using a Gateway DX4600-09 Computer:
    Athlon Phenom X4 9300e processor
    4 GB ram
    Ethernet - cat-5 to a 100 Mb switch.
    There are 9 other computers on the LAN (mix of XP, Vista and Linux)
    Performance starts out fine but will take a nose dive after a day or so
    connected.
    Right after boot:
    Machine to machine copies (mapped drives - to or from the 64 bit machine)
    will be in the 4 MByte per sec range.
    IE 7 works fine.
    Printing to a networked printer (has it's own IP address and is connected to
    the switch) works fine.

    Eventually:
    Machine to machine copies (mapped drives - to or from the 64 bit machine)
    will be in the 70 KByte per sec range.
    IE will stop loading web pages that were no problem before - it takes an
    extemely long time for a error to come up - usually an "unable to open page"
    error.
    Printing to the network printer slows from 30 PPM to about 1 PPM.

    This is not a gradual slow down - it will be fine on one IE access then fail
    on a reload just seconds later.

    Memory usage is ok - last time it was at 64%.
    Networking usage in task manager show no usage at all.
    Other than IE 8, Windows Update tells me I am current. (This problem has
    been occurring from day one).

    I do not have this problem on any of the other computers on the LAN.

    Where (and how) would I start looking for a cause?

    I would recommend trying these 2 changes. One or the other might help.

    1. Disable TCP auto tuning.
    In an elevated command prompt run
    netsh interface tcp set global autotuning=disabled

    2. Disable Remote Differential Compression
    Control Panel / Open Programs and features. / Turn Windows features on or
    off.
    Uncheck Remote Differential Compression.
