I have the same problem. It began after a blue-screen crash when I had just run (unsuccessfully) Norton 360's Internet backup for the first time. Has anyone found a fix?
I just purchased a new Sony Vaio laptop a couple of days ago.Its running the Windows Vista Home Premium program that was pre-installed on it from Best Buy. I hooked up high speed interenet on it via comcast cable connection. Everything was working fine on it the entire first day that It was hooked up. Internet worked fine through the Ethernet cable connection the whole time. I uninstalled the Norton Internet Security that was pre-installed on it and then I installed Mcafee security instead.Well the next morning I log onto the computer and everythng is working fine for a few minutes. Then I get this message in the lower right hand corner sayinng that a program from windows was trying to connect to the internet. I don't recall the message completely suffice to say that is said something about a UPnP client service or something. Mcafee asked me if I wanted to allow it to conncect to the internet though it was unrecognized. I didn't know what it was so thinking that it may have been something harmful I had McAFee block the access to it from the internet. Just then after I blocked it. Another box came up and said that windows was upgrading a one time change and would need to restart the computer. I was on the internet while it did like a two minute countdown to restart the computer. There was a lil green load bar in the box so I figured it was ligit. It finished counting and restarted the computer then when it came back to windows again I tried to get back online. It would not allow me to get online.
The small connection incon with the two computers on the lower right hand side of the toolbar on the bottom has a red X to show that it is not connected and the message that I get when I move the courser to it says
connection status: Unknown
Dependecy service or group failed to start
Also whenever I start the computer now. I get this little yellow lock symbol in that toolbar section and a box with a yellow triangle with an eclamation mark inside of it and the message says:
Failed to Connect to a windows service
windows could not connect to the System Event Notification Service. This problems prevents limited users from logging on to the system.As an administrative user, you can review the System Event Log for details for why it didn't start.
I'm unfamiliar with Windows so I'm not sure how to access the Event Log either. but ontop of all that when I look at the connectivity. It shows the Ethernet connectio as being enabled but not connected. I talked to the comcast internet service provider and she attempted to help me troubleshoot the issue over the phone but nothing was working.
when I attempt to connect to a Network I get a message saying that Windows cannont find any Networks. Even when I attempted to use a wireless router connection at my job to see if that connection would work instead it still says that its not accessing it. All the diagnostic test that windows does just ends up leaving me with the message; Windows cannot resolve the problem, please contact your network administrator or Internet Service Provider.
Then ontop of that when I attempt to click on the connect to the internet icon in the control panel it just gives me a message saying that the Wizard cannot continue:
The wizard is unable to continue and needs to be closed. You can try running it again later. If problem persists, please contact your system admin or tech support. when I click for more details it gives me this:
Error:(0x8007277B)< The error message could not be found>.
Failed to detect Internet connectivity
I have no Idea what is going on with my connectivity cababilities. Seems like everything was working fine up until that automatic upgrade that restarted my laptop happened. I don't know if me blocking that program that wanted to connect to the internet caused it or what.Even now while I'm writing this I just got a message on my laptop saying that there are multiple security issues with my computer. I clicked on it and it says that my windows firewall and automatic updating is off. I am unable to turn them back on...I'm so confused whats going on with my computer. I didn't get online until I was sure to have my security up and running so I don't see how it would be virus related and I've only had the laptop for like two days now.
I can't turn on the Windows firewall because it says that its not running and windows can't do it either...
The only thing that I can think of is somehow completely rebooting my laptop to start everything over from scratch. If you happen to have any input or suggestion that would help please reply to this....I have seen anyone with a post that was similar to my problem yet but hopefully someone can help...thanks
