Anyone know what svchost.exe NETWORK SERVICE is? It uses 100% cpu and it first uses about 6,000k of memeory and then it just uses more and more the longer it runs. It also freezes everything so nothing works, not even notepad.

Three svchost.exe are running when I use Task Manager. If I close this one everything is fine. So if I close this one two more svchost.exe are running.

Anyone know how to fix this?

In about 5 min it uses 28,000k of memory. Once I close it everything is fine.

Thanks,
Will

it's normal for it to be multiple copies and for it to use a large amount of ram, svchost.exe is a generic process name for a lot of network services, if one of them keeps using up a lot of ram then try messing with your services and see what happens, but it's normal for there to be more than 1 and for them to consume 28 megs of ram, at least

FYI - I have three running - total 23 mbs of RAM, that's normal.
Explorer.exe takes over 34 mbs of RAM.
What I worry about is the CPU figure for the processes, especially
iexplorer.exe.

Well its really ignoring becuase I have to close it every time I restart.

Closing network connections in services does not help either.

I had a similar problem a while a go when I was installing beta builds of Windows XP as they were being released and then the final without reformating and even after that it was still doing it. I think it must have been the order the processes started up. I tried messing with the services for a bit but it didn't help. After a reformat it all worked again though.
I spent a while working out what was wrong because when I started the computer it would seem to have started then I would launch something (happened with almost everything) and nothing would happen. If I just left the computer then after a very long wait it would sudenly come back to life and all the programs would suddenly start up.

After it got stuck if I checked one instance of svchost it would be using all the cpu. After ending 2 certain instances of svchost and then explorer and then ran explorer in the run box it would then usually come back to life straight away so I had to do this everytime I restarted.

I did make the problem go away for a while by optimising the registry which must have changed the order things started up in
Don't know if this problem is related but I thought it might help B)

I have 5 of them running in mine at a whopping 29 megs total RAM.

But War was not refering to the amount of RAM it was using. If I read his first post correctly, he was refering to it sucking up CPU.


FYI, the reason I have 5 running is because I also run VMware and that has 2 more network connections.

did you install Tiny firewall 3.0 prior to this happening?

bringing up an old thread back to life...

Hello everyone,

i have a question related to this svchost.exe.

Beta Spanky says: I have 5 of them running in mine at a whopping 29 megs total RAM. FYI, the reason I have 5 running is because I also run VMware and that has 2 more network connections.

well, i am not running VMWare. but i have 5 svchost.exe running. :huh:

SVCHOST.EXE: 1.95 MB
SVCHOST.EXE: 16.9 MB
SVCHOST.EXE: 1.29 MB
SVCHOST.EXE: 1.37 MB
SVCHOST.EXE: 1.38 MB

i just want to know if it is normal. two suspicious things occured in windows during last week, so i am curious.
thank you very much. :)

btw Will, i am 99.9% sure you are not running the same windows u had on September 2002 and hopefully u don't have your problem now.
me correct? :D

You have scanned for trojans?

Yea I dont have that problem at all anymore. Plus I only have two running now.

@.unicorn, no mate. won't they scanned by Norton AntiVirus 2003 Professional? i have that installed.
@Will, cheers!
@all, i just want to know if having 5 svchost.exe files is normal or not. anybody having the same #?

thanks for your replies! :)

I don't know if its normal or not but i have 5 instances, check the screenie

I have 4 running, is that normal??

Well lets just imagine that every service is running ok and they all show up in task manager.

Well then you would have a lot more than 5. So however many you have is because of what services you have running. Exspically if they are on automatic.

Here is a whole list I just created that uses the svchost.exe file.

Alerter
Application Management
Background Intelligent Transfer Service
COM+ Event System
Computer Browser
Cryptographic Services
DHCP Client
Distributed Link Tracking Client
DNS Client
Error Reporting Service
Fast User Switching Compatibility
Help and Support
Human Interface Device Access
Internet Connection Firewall (ICF) / Internet Connection Sharing (ICS)
Logical Disk Manager
Network Connections
Network Location Awareness (NLA)
Portable Media Serial Number Service
Remote Access Auto Connection Manager
Remote Access Connection Manager
Remote Procedure Call (RPC)
Remote Registry
Removable Storage
Routing and Remote Access
Secondary Logon
Server
Shell Hardware Detection
SSDP Discovery Service
System Event Notification
System Restore Service
Task Scheduler
TCP/IP NetBIOS Helper
Telephony
Terminal Services
Themes
Universal Plug and Play Device Host
Upload Manager
WebClient
Windows Audio
Windows Image Acquisition (WIA)
Windows Management Instrumentation
Windows Management Instrumentation Driver Extensions
Windows Time
Wireless Zero Configuration
Workstation

So each one of though services can make a svchost.exe file appear in task manager. Which ones, well I am not going through every single one just to find out.

But I will say these two on my system are the ones that casue svchost.exe to be dispalyed in task manager, that I am sure of:

Telephony
Network Connections

the machine i'm on at school right now has 3 running....

of that list above, the ones that i think that would cause it to run would be:

Alerter
Background Intelligent Transfer Service
Computer Browser
DHCP Client
Distributed Link Tracking Client
DNS Client
Internet Connection Firewall (ICF) / Internet Connection Sharing (ICS)
Network Connections
Network Location Awareness (NLA)
Remote Access Auto Connection Manager
Remote Access Connection Manager
Remote Procedure Call (RPC)
Remote Registry
Routing and Remote Access
Server
SSDP Discovery Service
Task Scheduler
TCP/IP NetBIOS Helper
Telephony
Terminal Services
Upload Manager
WebClient
Windows Time
Workstation

but, some services can use the same process as others, so, even if you have all of these running, you may only see 4 or 5 svchosts listed in task manager, which is also why each of them use different amounts of ram
