Limited or no connectivity

[Guest]

Hi

I have the devilish "limited or no connectivity" problem.

Here's what I did (may or may not be relevant).
Networking from my PC to the wireless router was working (via ethernet cable).
Trend Micro firewall showed an unknown machine on network so I blocked it.
It may have been this desktop PC.
I turned off the router and went home.
Came back and turned on the router and my laptop (wireless) and 2 Macs
(wired) obtain their IP adresses from the DHCP in the router and can connect
to the router and on to the internet.

The desktop PC (with the trend micro) now gets the limited or no
connectivity error.
I can not connect to the router (192.168.0.1) nor the other boxes.
I get the weird ip 164.x.x.x from ipconfig.
I ran the XP-SP2 patch and registry update - no help.
I tried the repair connection but get the can't connect to DHCP error
(sorry, I'm at work and cant reproduce the errors at the moment)
I found windows firewall on (I thought it was off) so I turned it off - no
help.
I turned Trend Micro personal Firewall off (at the same time as windows FW
off)- no help.
I can't get back in to Trend Micro view WIFI connections because "network
does not support WIFI" or something like that.
Followed TM help on how to re-activate service after blocking a WIFI
connection but could not find any "blocked" exceptions only "allowed" ones.

As soon as my wife gets back in the office I'll post the ipconfig /all
output and I'll attempt to talk her through setting up a static IP address.

In the mean time, Any Ideas?

Hugh

BTW, I just tried to get my wife to check the DHCP messages settings in the
registry and found that
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\DHCP does not exist
(it does up to VxD but no DHCP)

I also recall, just before everything going pear shaped, an IP address
conflict on this machine.

Could this be the issue?

i'm far from being an exper. but..

I got limited or no connectivity once when I connected 2 comps with a
crossover cable. It meant no itnernet access.

In your case this is clearly different. I'm not big on wireless. But,
do you have a bunch of comps connected with Xover cables and then one
cmop connected to the router?

On my wired system I have a bunch of comps connected to the router. My
Router does the DHCP.
If you have a simlar set up to this then
Maybe you're telling windows to do DHCP and that's the problem.
164.x.x.x might be windows assigned DHCP.
