Windows 7 loses network connection after reboot. Disable/Enable network card gets back on.

Hi

This problem occurs on a Windows 7 computer, every time it is rebooted it looses the network connection.  Disabling and enabling the network card resolves the issue until the next reboot.

I have looked around and found some possible solutions involving turning off the Bonjour services on the computer.

I have not tried any solutions yet as most support is done remotely. Rebooting is obviously not a good idea as I then cannot get back on.  I will try a few things when on site.  It would be great if anybody has some further input or ideas regarding this issue.

uninstall old network driver install new one (not newest one) - then go to windows update and install windows network driver - had that in some of my computers - they wont support original network drivers - have to be windows network drivers - other then that if you have something like firewall (comodo) uninstall it and have a look if that helps - maybe insert another network card in the box and have a look if this one drops connection also

Bonjour services can cause issues but I am with janpakula's suggestion, the network drivers are often updated and resolve these issues.  What's the network card make/model?  Are you on Windows 7 32-bit or 64-bit?

Delaying the Bonjour service appears to have solved the problem this time.  I agree with the above and have found that to be a good solution on other computers.  Thanks for the suggestions, it all helps when troubleshooting.
The other suggestions did not work in this case.
