Generic Host Process for Win32 Services

Hey all,

Zonealarm keeps alerting me of this process when i first boot up. So I let it do its thing, whatever, I don't care. Then when I try to use IE, it wants to access the internet. If I refuse it access, then it won't let me surf. What's up with that. Why is this a required process? I'll try installing netscape or opera to see if they depend on it to.

Any insight?

Cid

Do not allow Zone Alarm to start up automatically. Once your machine has booted, manually start Zone Alarm. If I tell ZA to start automatically on my machine, I have no net access (cable) once I boot. If I start it manually after the machine is booted, it works fine.

Sure you care, that's why you use the ZoneAlarm in the first place. Before XP, Microsoft couldn't get info from your computer (to send back to HQ's) unless you told your firewall to allow it. So, to get around that, XP (Microsoft) has been designed so if you don't give firewall permissions to its SPY s/w (Generic Host Process for Win32 Services), it won't allow your IE or Outlook to work. Once again, it's play my way or you can't play.

Someone said to start the firewall s/w after loading XP, not during... and this problem will not appear. Is this explained because XP's spy processes have been given time to start up and get a foothold?

I'd love to hear from anyone who knows more about this issue.

Crikey what's going on here then..sounds like Big Brother! It can't be really that bad can it? What information do they gleam from my PC for example..?

If it's 'play my way or you can't play' am I to adopt the attitude 'if you can't beat them join them' and learn hacking too?

For each internet session Generic Host Process tries to start up twice, once to handle outgoing and once for incoming. You onlu need the outgoing for web surfing. If you're running ZoneAlarm Pro (I don't know if the following is available for regular), deny the access for the server, but allow for the connect. And everything runs fine.

I found that if you set internet explorer to connect through a proxy, it works fine, even though you have disallowed "Generic Host Process for Win32 Services" access to the internet. F**K spyware.

I figured this was part of their new "Spy Ware". Anyone up for a class action law suit against Micro s--- for invasion of privacy? among a few other things?
As far as the recommendation above.
Only one that will work is using a firewall to let it connect but not act like a server (IE not allowing it to send any info ) Using this will allow everything to connect , NOT just IE. Like ICQ , AIM , VONs , etc.
Im going to be researching how the Generic Host COntroller works to see if it can be rewritten etc. IF so I will post it here.
Anyone else who has any ideas etc , be sure to email me.
Also I've figured out the "copy protection" they implemented on XP. You will laugh here. It's only a javascript that auto connects and confirms or denies. All I had to do was copy CD to hard drive exctract. rewrite , and replace this file.

If you disallow it to be a server and then scan the port it opens ( 5000 ) you'll find it is still open.Very tricky that. Now do this, scan every port on ya computer all 65535 of em and you'll be suprised how many are open even if you block all server access to the net. I'd like to know whats going on here

Look on Website www.windowsxp.nu

There is a XPAntiSpy.exe for download..

Also tweaks and optimizingtools...

Maybe that can solve the problem, cuz I have it too and I don't like it. But I want to use XP without letting a company know bout my whereabouts. I'm looking, reading articles and I've noticed that through the security-site www.grc.com there is allways a port open (also protected with Zone-alarm)..

that sucks fellows.. Don't know how to fix it, but it all has to do with this Win32 services for host processes..

Email your comments !

Greetz, dirty04

I found a way to completely block Generic Host Process for Win32 Services in ZoneAlarm (both incoming and outgoing), without affecting the ability of other apps to access the internet.

It has to do with stopping DNS Client. Go to Control Panel->Administrative Tools->Services, and right-click on DNS Client, choose Properties, and in the General tab, choose Disabled from the Startup Type combo box. Reboot.

I'm not the person who figured this out, and I'm not sure what the significance or possible adverse effects may be. Use at your discretion. But I can say I did this two days, many uptime hours, and many boots ago, and everything seems peachy.

Now if someone can enlighten us on why it works....

I have the same problem, found this solution: Go to Control Panel >Administrative Tools>Services.
Here you can find a list of services that are running, most of these (the ones you don't need)can be turned off by right-clicking on them and then selecting properties...
Many of these services run on svchost.exe which is causing the problem.
Example:
Automatic Updates => turn that sh!t off!!!
(be sure to check for dependencies)

Read all the foregoing messages and decided to experiment. It appears that the automatic updates is the culprit. Go to Control Panel > Admin Tools > Services and right click on Automatic Updates and click on Stop. It solved the problem for me.

The response by Daveo (No, 10) is the only one that works.You can set then Zonealarm to block Generic Host and you can still check Email, newsgroups, and surf.

Ialso would like to know what is going on here!

You cannot disable DNS without experiencing a lot of problems. Use Xp Antispy (a free download, find it using Google) to close most ports. Close some more by disabling Universal Plug and Play: regsvr32 -u upnp.dll
Then install Tiny Personal Firewall (find it with Google). Tiny is freeware, works on the same principle as Zone Alarm (no access, unless explicitly granted), but has no problems under XP. ZA does have problems, no matter what it's manufacturer claims.
You will still have some ports open, but only about five of them. And they are guarded by Tiny.

Good luck, Piet.

Like #10, I've found a way to have ZA block incoming and out going traffic on Generic Host without affecting IE or other apps., but without disabling DNS. Go to start, control panel, system, advanced, error reporting, and disable error report option. If you don't want auto updates you can disable that too in system. Then block out Host Processes altogether, reboot and you should be good to go. Adam

Using the search engine at http://www.google.com/ I entered "Generic Host Process for Win32 Services" (Quotation marks included) and Google found about 130 possible links. Among them was the link http://www.burningissues.net/cgi-bin/ikonboard/topic.cgi?forum=27&topic=8

If you would like to be really worried, then have a look at the page,
http://www.burningissues.net/cgi-bin/ikonboard/ikonboard.cgi?s=3c73c092485affff;act=ST;f=13;t=31,

If this link will work for you then you will need to go to http://www.google.com and enter "Generic Host Process for Win32 Services" (Quotation marks included) in the search panel, find and use the link. Then click on Security Issues under Off topic,and click on the icon to the far left of:- I believe MS is capable of this.


Among the various statements on this page are

"As a former employee of Microsoft in the know,"

"Microsoft has been compiling a massive database of names, registration codes, product keys, and linking them with data pulled from e-mail addresses stored in Outlook, Outlook Express, etc. as well as the serial numbers that can now be easily obtained from any Pentium-III CPU."

"Needless to say, anyone who hasn't disabled RPCSS.exe as mentioned above, has already been added to the database,"


The question now is:- Is RPCSS.exe related to Generic Host Process for Win32 Services trying to contact Microsoft?

Hey All,

This may not answer anyone's questions, but I've managed to find out how to get the list of what services SVCHOST.exe is running and I think ( once someone tells me what all the services are for ) that we may be a step closer to figuring out what is sniffing and what really smells.

Firstly, type "cmd" into the run dialog box, or open command promt from the start menu.

Then type "tasklist -svc" into the command promt ( obviously without the quotation marks ), then you should see a list of services. On my clean installed XP machine I get 4 instances of SVCHOST.exe running, with a total of 29 services running under them.

Heres the List:

SVCHOST.EXE Contestant #1 : ( PID : 824 )
Running : RpcSs

SVCHOST.EXE Contestant #2 : ( PID : 984 )
Running : AudioSrv, Browser, CryptSvc, Dhcp, dmsrver, ERSvc, EventSystem, FastUserSwitchingCompatibility, helpsvc, lanmanserver, lanmanworkstation, Messenger, Netman, Nla, Schedule, seclogon, SENS, ShellHWDetection, TermService, Themes, TrkWks, uploadmgr, W32Time, winmgmt, WmdmPmSp, wuauserv, WZCSVC.

SVCHOST.EXE Contestant #3 : ( PID : 1200 )
Running : dnscache.

SVCHOST.EXE Contestant #4 : ( PID : 1212 )
Running : LmHosts, RemoteRegistry, SSDPSRV, WebClient.

Now, I can see what some of the services are, but I don't know what all of them are, but i guess research will tell, and I noticed that RpcSs ( Which Is Mentioned In The Above Follow Up ) is running on its own SVCHOST.

I also have no idea what PID values are, but im trying to find out that too.

Anyway, there are some Follow ups on :

http://computing.net/windowsxp/wwwboard/forum/8400.html

I also posted what I found there, to see if anyone can help us all
