dhcp and dns defaluts getting changed

By nvgaa ·
Had my network up and running. Was moving a large file across the net when the entire net work went out. When I tried to access the network the network path could not be found. Internet explorer 6 could no longer access the internet nor would outlook express.

Checked all the settings all was fine. Called the isp the router was still connected and logged in. ran several virus software programs all but ms adware came up empty the ms adware found a toolbar program I removed it and ms adware asked if I wanted to reset the network defalt settings back to defalt I said yes. The network explorer and outlook all came back up ?alls well? tried to access the network and the whole thing went down again. Went to other computers on the network and none of them will access.

Something has changed my dhcp or dns settings or some other default in explorer or the dhcp system.

I tried reinstalling the network card drivers, setting the ip to a static ip changing the workgroup and reinstalling IE6 to no avail.

Ideas?

Note the network is set to workgroup connections with auto dhcp there is no one computer set up as the master as not all of them are used all the time.

Hi

What error messages are you receiving when you try to connect to the Internet, and what entries are in the Event Logs?

Sounds like your Winsock chain might be broken. You can try this fix here:

and this one here:

Often, spyware/adware will insert itself in the winsock chain. Removing the malware will therefore break the chain. Using either of these solutions should help.

Good luck

Check your hosts file, what does it look like? Often a virus or spyware will

Go to a command prompt and click run and msconfig press ok. Check in the startup tab and this will show you what is set to run when you start your computer. Anything unnecessary to operations can be unchecked - but your key files need to stay checked.

Run adaware (at www.lavasoft.de).

Download and run "hijack this". It will show you everything loading and running on your system. You will need to sort through what is legit and what isn't - but going forward running this every month or so will show you what's happening "under the hood" and will be easier to compare changes.

Sysinternals has a rootkit detector - but realize that it will show legitimate processes running as well.

There are lots of web resources on what each process does if I see one I'm not sure about I just google it.
