Network Hijacked??

By Regulus ·
I have a small in-house peer-to peer network using Earthlink DSL, Speedstream Dsl Modem, and Linksys DSL router. I have two 'serious' machines running win XP Pro, fully updated XP, Norton Antivirus & Zone Alarm Pro firewall. Others are 'sandboxes' and not routinely running on the net.
ISSUE: Machine #2 cannot connect to internet / p2p net. Zone Alarm reports 'New Network' with new IP of 169.254.16.227. Attempts to delete the New Network from Zone Alarm give Message 'Cannot delete active Server'. All attempts to reinstall p2p net fail. CAnnot ping out or in. Restoring to previous date ineffective. Unit apparently in server mode - will not interact with p2p.
NEXT: Machine #1 begins the same routine. SVChost attempts contact with 239.255.255.250, port 1900 on completion of boot. (I have net cable pulled). ZA Firewall 'Zones' completely empty. If I boot with net plugged in, I get 'New Network' at address 169.254.x.x, with 'x' being new numbers indicating possible DHCP assignment.
Shutting down 'Server' under services removes the pressence of the net, but then p2p still cannot be re instituted.
I have examined all start-ups in MSconfig etc and can find no program that could accont for start up in 'server' mode.
I do not wish to use Amnerica's (amost) biggest computer dealer's standard cure all of FFR (fdisk, format & restore)
I have been into Network Options and rebuilt p2p numerous times with no result.
Yes, I have run SFC.
Yes, I have MS Messenger svc fully shut down.
How do I shut down the invisible 'rogue' server and get back to p2p???
How do I shut down

Had a fellow admin get the same problem...

Hijacks are hard to track down manually, however, used www.lavasoftusa.com 's free adaware program (download to a cd along with updated Reg. file).

This program, after updated, will remove the hijack. After scan and removal is complete, reboot. Should be good to go.

Good luck

Hi,
Don't know if this will help, but the 169.254 addesses you are seeing are consistent with XP autocinfiguring an IP address. If the OS starts and is unable to get an addy from dhcp and one isn't specified then it will generate a random address in the 169.254 range and use that. running ipconfig /all will tell you whether or not the address in use is autoconfig'd or not. Autoconfiguration = yes means that autoconfig is switched on, whereas (and I'm going from memory) if an autoconfig'd address is actually in use you'lss see something by the IP address saying so.

Beer Monster, You got me the clue by which I was able to resolve the dilemna(sp?). Although my hardware 'seemed' to be working perfectly, your answer indicated that the results that I was showing indicated that I had an issue. Final resolution was disconnect and reset Router and DSL Modem, reinstall. Restart and go through the setup Net routine again. Yes, memyslfni1969@sbcglobal.net, I did this dozens of times. Then, after that, (still no connection) bring up the routers setup through IE and re-setup the router. Everything worked immediately!!! Strange thing was that I had one sandbox computer that always worked. It was running XP Home instead of XP Pro. But, if the router worked on one port and the others were not physically defective, the other ports 'should' have worked also. In this wierd case, the re-run of the router set up program shook the other ports back into action - or did they? I definately tried port swapping with no results!! I also have absolutely no idea about what initiated this issue. No results from Norton, Adaware, Pest Patrol or anything else pointed to any possible culprit. I thank all of you for your assistance. It is deeply appreciated

Thank you for response. Yes I tried updated Adaware and Pest Patrol, not effective.

Yes, that appears to be exactly my issue. But my problem is that I can't force the unit out of server / network mode, back to p2p. Any suggestions?

Have you tried system restore?
