Network discovery turned off by mistake, can't resume!

I turned off vista network discovery by mistake, then no more internet. I tried to resume it, but failed. Since the option screen disappeared. Please help!
Thanks a lot in advance!

Hello. go to start button> type services in the search pane. then open up services, and check the network services, you can re-start them by right clicking, properties, set to auto, auto delayed, or such from there, when done, restart computer, check if enabled at this point, Post back if this worked please.

Thank you so much! Yard Dog, I'll try it tomorrow.

Good morning! Yard Dog and Everyone,
I tried what you suggested, but failed. When I opened up the services, it shows commercial network services, such as: DSL/Cable, Broadband Phone, AOL , etc. My computer has university broadband connection, so nothing to do with the commercial network services.
I know my internet disconnection was caused by mistakenly turning off the network discovery.
It suppose very easy to solve the problem by just turn on network discovery. But the problem is the “network and sharing center” window no more shows the “turn on/turn off” options! I got very frustrated by this problem.
Does Vista have the function to resume network setting? Maybe you have other methods to fix the problem. Many thanks!

Some information about the computer bellow:
Windows Vista Home Basic
Service Pack 2
Computer: Compaq
Model: SR5010NX, Processor: Intel® Celeron® D CPU 3.46GHz 3.47GHz
Ram: 1.5GB
System type: 32-bit Operating System

Hello, i meant the window services. Not those, i am thinking in windows services you have disabled one of those. Type “services.msc” in the Run box without the Quotes , then you will see what i mean.

Hello Chicagojin and welcome to the forums

Yard dog has had to pop out for a few hours and has asked me to step in to get you up and running as soon as possible I think the easiest way out of this mess is to do a system restore point to a date before the problem started:

Let us know how it goes!

Hi, Tom and Yard Dog,
I followed Tom's suggestion and opened the SystemRestore folder, but I didn't do anything. Since the problem started yesterday and the system already passed the default Point: 12:00AM. I searched SR Properties/History (see bellow):

Hi Chicagojin,

Can you download the attached VBScript and run it please? It will check your system restore points and output that to a text file, then open it. Please copy and paste its contents into your next post for us

Tom

Hi, Tom,
I downed it, but my computer can't run it(I downed it to a flash drive, then tried to use the problem-computer to run it, but failed). Please direct me how to run it. Thanks!!

Hi Chicagojin,

Tom

Hi, Tom,

I give up with the system restore, I have no idea what's going wrong

Yes, give those fixes a try next

Tom

I agree with Tom, i was gonna go with dns flush and ip reset next. Lets see how those work out. Post back results please.

Hi,

What AV & Firewall are you usiing?

These can takeover control of the network device viewing in Network & Sharing, well Norton 360 does. Cus I have that!

Hi, Yard Dog and Tom,[FONT=&quot]
[/FONT] [FONT=&quot]I tried the solution. When I put “netsh winsock reset catalog, it shows: "the requested operation requires elevation." So I think maybe I need to reinstall Vista or windows 7?[/FONT]
[FONT=&quot]I'm leaving the office now, I'll try something tomorrow.[/FONT]
[FONT=&quot]Thank you so much for your great help!
[/FONT]

Hear ya, on the going home , Tomorrow, do this. Flush the dns using elevated command prompt , Start, all programs, accessories, command prompt ( right click this ) This opens up command prompt for admin if you right click and select run as admin. Then do this : type in ipconfig /flushdns
Once that is done, then type this in. type in ipconfig /renew.. notice the spaces. this will reset your ip connection. After you do this. Post back results please.

Good morning! Yard Dog,
I did that as you instructed, here is the results:
[FONT=&quot]C:\windows\system32>ipconfig/flushdns[/FONT]
[FONT=&quot]Windows IP Configuration[/FONT]
[FONT=&quot]Successfully flushed the DNS Resolver Cache.[/FONT]
[FONT=&quot]Windows IP Configuration[/FONT]
[FONT=&quot]The operation failed as no adapter is in the state permissible for this operation.[/FONT]

[FONT=&quot]what should I do next?
