Local Network Service Memory Footprint And Services


I've just upgraded from windows xp to windows 7 and i'm examining what has been installed and trying to remove things which i dont use.

For example i have removed all drivers i dont use or need (like qos) from the network device.

Yet i have services like ssdp running - strangely enough i know exactly which devices i have on the network and the computer is directly attached to all of those and should in theory not need to have any discovery services running.

How can i manage which services are running and control what exactly ia being run on my computer network ?

I notice the local network service has a foot print of around 100mb regardless of wether i'm connected to the internet or not - i cannot understand why this service has such a large foot print. How do i control what is being run in this service, is there any way to stop the service from running and only start it if i need to use the network ?

I also wish to stop tcp/ip helper service from starting as there is no reason why anyone shold need echo requests from my computer, i could disable this by uninstalling the driver, is there anyway i can do this ?

As far as i understand i dont need ssdp, ntfs, tcp/iphelper, dtc, fdphost, grouppolicy client, homegroup provider, network list, nla, ftp server, windows connect wifi (i dont use wifi), windows media network sharing, .

Some of the other services look doubtful to me as well.

How can i reduce these services which i certainly dont need at the moment ?

Error - Local Printer Spooler Service Is Not Running

"local printer spooler service is not running" error; any attempt to add a local printer (usb or bluetooth) fails. I cannot add a printer (usb or bluetooth), as it always returns a printer spooler error. I've tried restarting the print spooler, and making sure that "local system account" and "allow service to interact with desktop" is selected. I've also removed all old printer drivers, restarted, checked the rpc locater is active, and tried everything else i can think of.

This worked fine in vista x64 on the same machine just yesterday, but the upgrade to windows 7 x64 seems to have broken something. The printer, an hp c5500 series, works fine on a virtual machine running the same os. (I'd rather not have to run a vm just to print, of course. ) Running rtm x64 on a dell xps m1530 that printed fine from vista just before the upgrade to win7. Suggestions?

Error: Local Print Spooler Service Is Not Running

Since upgrading from vista to windows 7 on my toshiba laptop, i have not been able to add any printer to my computer. I get an error that says "local print spooler service is not running". I haver run the built in troubleshooter and gone in manually to turn the spooler on. Everytime i do this all printer icons stop responding and when they do finally respond, the spooler is "stopped" again. What can i do?

Can't Open Add Printer - The Local Print Spooler Service Is Not Running

"windows can't open add printer. The local print spooler service is not running. Please restart the spooler or restart the machine". I am running into the same problem on an emachines et1331g.initially, i wanted to print to an older dell - found the driver was not windows 7 compatible so installed my canon px100 successfully and used it for over a month with no problems.

Then i needed to move the computer to a different desk and install a driver for an epson nx415. Using "add printer", the message says "windows can't open add printer. The local print spooler service is not running. Please restart the spooler or restart the machine". Restarting the machine does not resolve the problem. In control panel/admin tools/services/print spooler, the spooler is set to start automatically and will sometimes show started, sometimes not.

If i start it and then go back to devices and printers, the epson will show that it is installed and ready. But if i then try to print something, it says "before you can perform printer, you must first install a printer". If i logout and return later, i will find the spooler no longer running.
I have tried the latest 64 bit drivers from epson with no success. I am running windows 7 home premium 64 bit. Any ideas?

Re-enable The Virtual Machine Network Services Driver

To fix this problem, re-enable the virtual machine network services driver on one or more ethernet adapters or reinstall virtual pc. Upon opening the freshly downloaded virtual pc 2007 from the windows orb, i was presented with a caution-virtual pc dialog box. After reading the short warning i proceeded on trying to find solutions. I've uninstalled installed virtual pc a couple of times. I cannot find anything about virtual machine network services drivers. Can you help me?

Media Player Network Sharing Services Issue

Right after i go on line media player network services grabs 2gb of memory and 70 percent of the cpu usage, and the hard drive usage light comes on solid - this makes using the internet almost impossible since the clock is on for several minutes at a time - this computer is only used by two 'users' and only has a limited amount of stored music, no videos or tv shows - how can i shut off the service - or restrict it's ability to consume resources. This is an acer aspire 5532 with 3gb memory and a 160g hdd.

Unable To Connect To Local Network

For a few days now, i have been attempting to resolve this problem where i cannot connect to the internet via ethernet cable. This computer does not have wireless internet. When i run the network diagnostic tool, i get the message:"the 'local area connection' adapter seems to be experiencing driver or hardware related problems. "To attempt to fix this, i downloaded the most up to date network drivers for the adapter, i have an asus m2n-sli deluxe motherboard, aka nvida 570 sli amd.

This did not solve the problem. With further reading, i have tried several things, disabling then re-enabling the adapters, shut down the computer, unplug the ethernet cable, and plug it back in once it starts up, and disable internet securities. Interestingly, i have also noticed that i am unable to run my mcafee anti-virus scan. Has anyone experienced this issue and/or know a solution to fixing it?

Media Player Network Sharing Service

After upgrading to a larger hard drive i reconnected my xbox 360 to my home network and began re-sharing my media on my main computer to it. I don't leave it hooked up all the time because the cable has to stretch across the floor. The odd thing this time is, i came in to use my computer the next day and it was slow, very slow. When i looked at the gadgets it showed my ram usage as 94-97%! 

When i started up the task manager and had it show all processes, the windows media player network sharing service was eating up that much ram. I shut it down and within minutes it had started up again and began eating ram like it was candy. It only took it about 3 minutes to once again eat up nearly all 3gig of memory. I have to  go in and shut it down manually at least 3 times a day.

User Profile Service Service Failed The Logon - Login Problem

When i return to my computer after being away it says 'locked' under my username. And i think once i logout it keeps me from logging back on. We just last week purchased a dell xps 8000 with windows 7 installed. Some nice features but also it's share of bugs, such as random freezes. And this one; the second day i noticed the word 'locked' next to my username. I am an administrator, if that matters. Some time later i logged out and at my next login i got the error message "user profile service service failed the logon". The end result was that a dell tech. Did a system restore, which got me back up and running. I didn't log off last night and when i first looked at my screen this morning it says 'locked' again by my username. I am working with no problems now but i'm scared to logoff. Why is this happening and what can i do to fix it?

Services Settings

I have been trying to maximize the performance of my rig since i only have 4 gigs of ram and my ancient 1 year old mobo can hardly cut it with windows 7 (sarcasm intended). So, i have been fiddling with services but i occasionally mess things up and i end up painstakingly trying to reset those service back to their defaults, one at a time. How hard could it be for the services panel to have a ‘default" or "reset" button? So when people like myself (i’m not very smart) mess up a setting, we can simply click "reset" and the ole’, comfy, default services fix my screwup. Are there other ways to do this other than the aforementioned "by hand" method. Software? Utilities?

Interactive Services Detection Error

On bootup this morning i have been bombarded by a 'interactive services detection' dialog box - i've never heard of the program and am unsure what to do with it. Closing out the dialog box will make it disappear for roughly 10 or so mins, on which it will then return. I had a bluetooth detection warning or error this morning as well(i didn't see what it said before it went away).
 
I'm running win7 x64  on an alienware laptop - i ran mcaffee as well as some other security programs  and nothing popped up with an security issues - so i'm guessing that this is actually a windows program(although i have not heard of it). I went through google and a few of microsoft's sites and have yet to find any information regarding what the parent program is, what it does, how to disable it, etc.
 
I bought this laptop new, around 6 months ago and this is the first time i've ever encountered this particular error/dialog box - i did not install, download, or change any programs recently(within the past week, minimum). So i'm a little stumped as to why this is coming up now - with no changes to my system. So if anyone could provide some help/literature  on what this program, it's parent program, and anything connected to it does, is, etc and if this program is in actuality a virus or just a program, and to what i should do with it(delete, repair, etc) would be greatly appreciated.
 
>Win 7 x64
>Alienware laptop
>Most if not all drivers, updates, etc downloaded and applied
>Wireless router, bluetooth printer/fax(not connected to this laptop)

Repartition Memory Stick / Memory Card

How to repartition a memory stick or a memory card? So, i bought an 8 gb memory card and figured i could create a couple or a few partitions on it; perhaps exfat and fat32 ones. I fired up the disk management program only to find out that the flash memory disk has the shrink/extend/delete volume controls greyed out. I did manage to shrink the volume using the disk-part command line program but couldn't use it either for creating new volumes.

Where does this seemingly ridiculous and pointless restriction stem from? I only found a couple of instructions on how to partition a memory stick using some shady third party programs.

Terminal Services Default Printer Issue

In this message, the user is having trouble in windows 7 losing the default setting on a printer. Alan morris from microsoft chimes in noting that this is an "old" terminal services issue. I believe i am having that terminal services issue. I use remote desktop to my office workstation. I have my home printer's driver loaded on this office workstation so that i may print to my home printer when remotely connected to my office pc from home.

When i break that connection - usually by just closing the mstsc window - my office pc does not return the default setting to my typical default printer. Either my default setting is lost entirely (no setting at all) or the quickbooks pdf printer gets set as the default. Can anyone help? Especially since this might be an old issue related to terminal services?

Active Directory Domain Services Unavailable

I'm running windows 7 and after the last set of updates (4/15/2010) i can no longer access the print servers (version 2003). It gives me the message: active directory domain services unavailable. I have verified that dns is set up properly and have tried without the firewall active. I have also tried doing a system restore but that failed to fix the problem. I suspect a registry issue as i have the same problem regardless of what problem i try to print with.

I am also now having a problem with adobe and am getting the error message: unable to print: no pages were selected to print. I noticed that these patches are for patches. I am also unable to use the diagnostics program because it says i do not have the "download a file periodically that helps determine system problems" box " checked even though i do. My computer is a tool that is useless with out this ability.

Active Directory Domain Services Not Available At This Time

I know this has come up before but i am at my wits end and i seem to have tried everything. I have a dell studio laptop running windows 7 connected by wireless to a bt home hub. It is connected, i thought locally, to a hp laserjet 1100 printer. Recently, suddenly, it refused to print out of word 2007 (and excel 2007)and the error message above has been displayed. I have tried re-installing the printer, both as myself and as administrator. I have tried troubleshooting, but this reconnects as a network printer and nothing happens.

I am not expert enough  to start doing professional things. Is there a fix or will i have to but a new printer? The annoying thing is that my imac works fine, but for some things i need to communicate via windows.

Services Explorer.exe Don't Work

I have windows 7 32 bit home edition installed, when i start my computer after logging in there is a message that says "c:windowssystem32system profile desktop not accessible, check user-name and password. " In the middle of the screen and my desktop is all black with no icons. In the lower right hand corner a bubble that says something along the lines of "could not connect to user profile service, this may prevent normal users from logging in" pops up as well. Anything i try to run either does not respond or says "the server process could not be started because the configured identity is incorrect.

Check user name and password.initially i did a clean boot and it brought back my desktop and allowed some programs to run (such as eclipse, skype, calculator and others) but i was still unable to get explorer.exe to run. However this no longer works although this functionality will come back seemingly randomly at times. The only thing i can think of to fix my computer is to re-install win 7 but i don't have a disk, i only have the download on my computer and last time my desktop came back i tried to run it but i got the "this service cannot be started" message. Safe mode works, there doesn't appear to be anything wrong with it other than the fact that it is safe mode and doesn't have full functionality.

I can't do a system restore as it seems i accidentally turned it off at some point and there are no restore points. I have tried sfc /scannow with no success. I tried looking for problems with registry keys but i haven't been able to find instructions on how to fix possible problems related to this in win 7 and seemingly similar problems in xp/vista don't seem to have the same structure for registry keys. Does anyone have any ideas as to what i can do? I'm at a loss and can't think of any thing else to try.

What Is A Local Administrator?

Background to problem: i just bought a dell inspiron lap top, it had windows 7 64 bit. In an attempt to run a old xp program i updated to windows 7 pro. Xp mode doesn't work because my computer doesn't support hardware assisted virtualization.

The question: now when i open windows i am told i have to upgrade microsoft network or it will not run. When i try it tells me i have to be a local administrator to upgrade. I am logged in as an administrator. How do i get the computer to shut up and stop with the big box. I don't really want to run ms network.

Installed Memory Versus Available Memory

I have installed windows 7 64 bit as a clean install on a second disk in a system with windows vista 32-bit running on the 1st disk. The install went fine, and the system is running well. However, when i check the system resources i am told that there is 4 gb of memory installed but only 3. 49 gb available. Is this because i have the windows vista disk in the system. The mbr shows both systems are bootable, and the windows boot file and winload.exe are located on the vista disk drive.

This leads me to believe that i have inherited the 32-bit memory restriction on windows vista. On another system, a new laptop that came with windows 7 64bit pre- installed, also with 4 gb memory, the system resources show that there is 4 gb of memory, without any restriction on what is available.
