There are 50 computers in our office and 20 of these are having network issues. These issues did not begin until we did an office wide upgrade to Windows 7. We have 3 windows 7 enterprise x64 bit and the rest are 32 bit. We use all Dell computers - some have Intel Network cards and some use Broadcom network cards. All computers have updated drivers for both network cards. I used a command script to stop the offload. netsh int ip set global taskoffload=disabled This seems to help a little but slowly the computers have slow internet connection. We run a T1 using cat 6 connections and have checked our switched for functionality and the connections are live from the wall. Our temproray fix is to uninstall the network adapater - shut down the computer - wait a 30 seconds then turn the system on to reinstall. Again this is temporary and really troublesome when every employee calls you in the morning after they restart their system. Any suggestion that I may be missing... pretty please please!!!!
