Solved Can't access "Network and Sharing Center" nor "User Accounts"

newbie · Oct 17, 2008

The control panel opens fine. I can access all items in the control panel
except "Network and sharing center" and the "User accounts" (I can't access this sections via the taskbar either).

What happens when I open one of the two items is I get a popup saying the
following; WINDOWS EXPLORER HAS STOPPED WORKING.

I used to be able to access these items. And one day, I just coulodn't anymore...

Anyone knows how to solve this? Thanks.

I'm using Vista Ultimate x64

Hello Newbie,

See if running a sfc /scannow can find and fix bad system files that may be responsible for this.

Hope this helps,
Shawn

Thanks for the reply. Unfortunately, after doing that, no errors were found...

If it has not been more than 90 days since the problem, you can also see if doing a System Restore using a restore point dated before this problem can fix it.

I tried running sfc again, on an Administrator Console. I get the following error: "Windows Resource Protection could not start the repair service."

As i said in NBR Forums , you can try this

Some Windows Vista functions may not work, or Windows Vista may stop responding

OK. Instead of running an administrator console from a shortuct (that made the first path of the console be C:\Windows\system32), I've run the console from the Start Menu (that goes to C:\Users\<myUserName>).

Running sfc \scannow from there worked...

According to the log, the file "shigna.dll" is corrupt:

Code:

Although there are four entries, am I right to assume that the error is in only one "shigna.dll" file?

re: Can't access "Network and Sharing Center" nor "User Accounts"

I have the Vista Ultimate with SP1, so here is a copy of that file from system in a ZIP file if you wish to replace yours with a clean copy of it.

You will need to save the ZIP file and extract the shgina.dll file to your desktop first. Afterwards, you can Copy and Replace the shgina.dll file to it's default location at C:\Windows\System 32.

Hope this helps,

re: Can't access "Network and Sharing Center" nor "User Accounts"

It worked.

YAY!! Thanks for the help. One final question: to overwrite the shigna.dll I followed the takeown \f -> GRANT ADMINISTRATORS:F steps. How can I protect shigna.dll again (make it like it was before)?

Thanks.

Brink · Oct 18, 2008

re: Can't access "Network and Sharing Center" nor "User Accounts"

Your welcome,

When you took ownership of the old copy, it will not affect the new copy. The new copy should have the default owner as TrustedInstaller automatically.

newbie · Oct 18, 2008

re: Can't access "Network and Sharing Center" nor "User Accounts"

I thought so too, but I was able to overwrite the newly pasted shigna.dll with the old one, via Copy-Paste (through Windows Explorer).

But before, I couldn't (an error message appeared, saying I didn't have permission).

newbie · Oct 18, 2008

re: Can't access "Network and Sharing Center" nor "User Accounts"

I'll follow your guide.

Brink · Oct 18, 2008

re: Can't access "Network and Sharing Center" nor "User Accounts"

You can just check to see what it has listed as the Owner. If it's anything other than TrustedInstaller, then you will just need to change it to TrustedInstaller. I would not think that you would need to though.

newbie · Oct 18, 2008

Even after following the guide, I can copy-paste and replace the file/delete it.

And TrustedInstaller is the owner.

Brink · Oct 18, 2008

Great news.

I'm happy to hear all is ok now with it. :geek:

newbie · Oct 18, 2008

The problem's that even TrustedInstaller being the owner, the Administrator still continued with Write, Full control and Modify permissions.

But I've manually removed those permissions. Probelm solved.

Brink · Oct 18, 2008

Good deal. I added a note at the end of the TrustedInstaller to help remind folks about also changing the permission level back to.

Thank you,
Shawn
