I already posted this in the networking forum, but I guess very few people monitor that forum and this may be a XP problem as well, so I am reposting this here and will delete the other one.


Hmm this seems to be a strange problem.

I left for vacation last week, did not touch my laptop, came back and now it will not connect.. it seems.

I originally was unable to obtain DHCP automatically, was getting limited or no connectivity. So I was confused, I ran xpwinsock fix and no go. So I changed to a static address, and was able to fully connect. Well, thats what it says. I open internet explorer or firefox, they are slow to open, and they do not show pages, just, canot find server messages.

So I began to think, maybe we have a problem with COMODO or NetPeeker. So I disabled both, still nothing. Ran LSPfix to locate problems, everything seemed fine, ran malware bytes, spybot, and nod32, all clean.

We did no changes to our network here, and I made no changes to my laptop.

HOWEVER!!!

On my last day before my vacation I was getting hit HARD with SYN flood attacks, thousands of attempts. Thankfully NetPeeker does a pretty good job at blocking these. So it may be possible that a problem could have occured there.

I have tried everything I can think of, any other suggestions???

If you are using a router, disconnect from the net, reset the router and give it a strong password.
You might want to run some virus scans Look for DNS trojans
Try Mbam if you'd like
-----------------------------

Please download Malwarebytes Anti-Malware and save it to your desktop.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
  • MBAM will automatically start and you will be asked to update the program before performing a scan. If an update is found, the program will automatically update itself. Press the OK button to close that box and continue. If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
  • On the Scanner tab:
    • Make sure the "Perform Quick Scan" option is selected.
    • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
  • Back at the main Scanner screen, click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes, they may alert you after scanning with MBAM. Please permit the program to allow the changes.

I already ran malware bytes and spybot and nod32, everything was clean.

However, last night I tore into it some more and removed COMODO, and deleted all the rules set by Net Peeker and rebooted the machine, and sure enough, it all works fine now.
