Network and Sharing Center Freezes, Taskbar icon broken

Two things, whenever I attempt to enter Network and Sharing center it usually comes up blank for awhile, and then eventually (maybe 5 or 10 minutes) the information will show up but I can’t select anything and there’s no way to exit the window and it just remains on my taskbar unless I restart.

Also, the system tray icon in the bottom right corner always shows disconnected (even when I am) and also if I right click takes a few minutes before responding to my click, all during this time my being able to use my computer freely but eventually the menu will pop up. If I hover over this icon it just says:

Connection status: unknown

Server execution failed

But, I am connected to my wireless network and can access the internet etc.

I’m not sure if this is related, but Windows Update always comes up with an update for Microsoft SQL Server Service Pack 2 or something, and I’m pretty sure that it never successfully installs, because it says that it does, but every time I ‘Search for new updates’ it’s still there.

Thanks for the help, this isn’t usually a big problem but I’m trying to alter some of my network stuff and it’s becoming a huge pain and I can’t do a single thing with it. Thanks a lot!
