Advanced Sharing button --> Admin has blocked you --> Class Not Registered

Hi,

VERY odd issue.

Windows 7 Pro
Using Advanced Sharing Button when trying to Share a Folder (normal Sharing works ok) I get a popup saying:
"Your administrator has blocked you from running this program" and in smaller test it says  "Class Not Registered"

Normally, when you click the Advanced Sharing button here, it opens the manual "Advanced Sharing" sharing window, NOT to be confused with the Network & Sharing Center Advanced Sharing page...

I know it used to work, so I must have done something in my recent tweakings to mess this up.

1) System restore doesn't go back far enough to correct this.
2) I would rather not do a re-install.
3) I can not re-register NTSHRUI.dll as it errors out about an entry point or some such, presuming this is the DLL that is executed when you click the Advanced Sharing button.
4) All the googling I have done has not turned up any useful info, other than my own post in Technet Forums.

5) Related or not, SFC /scannow chronically terminates at 18%

6) The rest of windows seems to run pretty well.

Any ideas ?

Thanks in advance !!

Hi,

So last night I got antsy about this problem.....   I created a system restore point, then I exported my entired registry, and then I rebooted into my other win 7 "clean" partition I have for testing things and exported its entire registry.

Then I rebooted back into my normal partition, the one with this issue, and imported the entire registry from the clean partition.....  Stupid yes, but it was the only way to see if I could fix this odd issue without a re-install.

Amazingly, it fixed the problem....  well that is until I restarted and tried to go back into this partition.....  Not unexpected, I could not get into it, even in safe mode....

Restarted off my Win7 DVD and ran Startup repair & restore....took it quite a while, but when I came back, it had put my partition back into a bootable condition.  However my odd issue had returned.....

grrrrrr.....

Hi,
Thanks for the reply.

I have 2 other user accounts, and
both show the same behavior. One is older
and the other is about a week old.

Very odd that it came back after a repair install.

In fact you fixed it twice then it came back. The "Class Not Registered" is normally an error that it cant find a dll or oc file it needs. And that info is stored in the registry, which you resotred twice. It seems like something is removing the reg keys for the file it needs.

I use to have a copy of this

It was how I would find any registry changes.

I would make a snap shot of the registry, then go change what I wanted (Like a Windows setting) then take a new snap shot and have it compare and it would show me all keys that where changed.

It is how I find what reg keys are used with a lot of things :-)
