Networking Issue

[John Harris]

I have recently (the last week) had a number (5) of Vista PC's (mostly Home
Editions but two Business) turn up with network issues. The issues are that
they seem to lose their Internet connectivity. When I get to them they are
all using DHCP but have ended up with an APIPA address. When I run the
Repair and Configure wizard the issue remains. I have tried:
1. Running the wizard
2. netsh winsock reset (I know!)
3. netsh int ip reset
4. Manually configuring the IP (whilst you sometimes get a connection it is
very slow it doesn't always work)
5. Followed KB928233
6. Reloading the original NIC drivers (these are various NIC's ranging from
Realtek, Braoadcom, NVidia, etc and both wired and wireless)
7. Uninstalling the NIC and reinstalling
8. Trying different routers (both cable and ADSL - Linksys, DLink, Netgear,
Thomson, etc)
9. Running Malwarebytes and Spyware Doctor (full scans just in case it's
malware - but no majors found and no improvement)
10. Moving to a different network (my workshop and also another local
franchisees workshop)

Any assistance would be most appreciated

With Vista, you need to check the Scalable Networking Options settings. Some of
the options won't work with all routers, and will cause problems.

And there are 2 settings which affect DHCP, in Vista.

Hi Chuck,
Thanks for the suggestions. I will try these tomorrow when I go back to
work.
