Hello Experts!
very happy new year !!

One of our customers uninstalled a program they had for several months its called "FACEBOOK BLOCKER."
Now they need to access facebook for some of their activities so they uninstalled that software

Problem is still they cant access...

although it's not our responsibility they do rely on us for these little things...

I have reset internet options but still, Facebook is blocked...
What else can I do here?
Regards,

Do they have a firewall in place?
RGuillermoProject ManagerAuthor Commented:
checking that..

If they ping facebook.com does it resolve?

Maybe check c:\windows\system32\drivers\etc\hosts file to see if there is a manual entry.

What web browser?  All web browsers are blocked or just some/one?
Installed on the computer?  On a UTM?
What exactly happens now?  just can't find Facebook?  A message says facebook has been blocked?  What?  SPECIFICS really help a lot.  Screenshots can say 1000 words (or more).

I had to wait for user lunchtime, sorry.

Brian, yes it resolved when pinging www.facebook.com

Usmad I disabled the windows firewall... still can't access facebook

Lee,

this is the image in all browsers
Please see attachment.

Could it be something in the registry ?

Just a hunch, but you could try www.fb.com instead.

Other than that, we need to narrow down where the problem is located. Next step would be check the network firewall and see if the request is getting there and if it is going through. Are other users working okay? Those answer will tell us if the problem is the PC or the firewall.

Can you please try these commands in CMD.

IPconfig/release
ipconfig/flushdns
ipconfig/renew

Brian,
www.fb.com does not work, the Same message.
the block is on all machines in the LAN

this is a remote pc LAN for me so IPCONFIG /RELEASE got me out of the station,
now I am waiting for somebody t come back from lunch to restart that machine.

You could try toggling between https and http in the url to see if both are blocked.

It could also be a restricted website under their internet options. In Windows, this can be checked by clicking on the window start button, clicking control panel>network and internet> internet options. Click the security tab in the internet options panel, click restricted sites then the "sites" button and see if facebook is showing up here. If it is simply click on the site you wish to remove and click the remove button.

If this doesn't work, you could try a portable proxy browser that may allow them to access restricted websites. KProxy is one I would reccommend. I linked a free download of that product.

So if all machines are doing this, you might be looking in the wrong place by trying to fix one machine. Not that it isn't possible, but check the *network* firewall first to make sure that facebook isn't being blocked there.

-On Elevated CMD enter netsh winhttp show proxy and see if a proxy is set at that level, (Should say Direct Access in most cases)
-Check your NIC for DNS settings. Perhaps it is using some random DNS server.
-Try running netsh winsock reset from elevated CMD and reboot
-Uninstall your NIC from Device Manager & re-detect it. Some odd protocols might have been added
-Check browser extensions.
-Temp disable AV solution if this has a build in firewall
-Look for program remnants in add/remove programs.
-It is possible that you need to re-deploy the app, enable FB access inside the app, then remove the app.
Sometimes when setting an app to block stuff, then removing the app, it leaves the blocks in place.

If none work perhaps try to find out which application was deployed for more accurate advise :)
BillDLCommented:
Does your customer recall whether the Facebook Blocker application or browser add-in was able to toggle from "blocked" to "unblocked"?

It sounds to me as though the application or plugin was removed while it was set to "blocked", and I am wondering whether it might be a good idea to reinstall it and set it to "unblocked" before uninstalling it again.
Brian BEE Topic Advisor, Independant Technology ProfessionalCommented:
I assume this was installed on all systems. Do you have any indicators left on any of the systems about what the program was called? There seem to be a lot of apps advertised that do this.
