When I log on a wireless configuration message pops up - Notification dll has not been registered, program will not work correctly.  I did register the hardware with Lynksys and verified it on line.  I am still getting connectivity to the wireless router but not sure how resolve this message.

What wireless application are you using?  I have Windows 7 on an IBM Thinkpad and I search through Program Files, Program Files (X86) and all of c:\Windows and subfolders and do not find notification.dll.

does it name a specific dll file?  A dll is usually a file required for a program to work, it is short for Dynamic Link Library.  

If it names a specific file that it says is not registered you can register it manually, though you shouldn't have to.  It should have been registered when you installed the software.

Here is an explanation on how to register the file:

You would likely just need the first 4 steps.

the error message is notification dll - no periods, so am wondering if the dll file is for notification?  I am not sure how to answer the question about which wireless system - I think its linksys

Ok from the sounds of it there is no DLL named, its just a notification window telling you that a dll file has not been registered... hmm.

Could you post a screenshot of the message maybe?  

Are you using a laptop with a built in wireless card or is there something you plug into the computer to connect to the wireless?  If so, is linksys the brand on it?

Thank you for clarifying.

With respect to which wireless application, my Windows 7 system has Windows Wireless (which works) and Access Connections (which also works very well). But neither of these provide any errors about a DLL.

That all sounds about right. The message does not arise from the router.  So two things:

1. Per RaithZ please post a screenshot of the error.
2. Go to the Dell support site for your laptop and download the newest wireless driver and wireless application.
3. Uninstall the Dell wireless application, update the wireless card and then reinstall the new wireless application.

See if the error persists. ... Thinkpads_User

Did you recently reformat your computer by chance?  Or did this just start happening out of the blue one day?

Try this:

Open the control panel and double click administrative tools, from there double click 'Services' and look for the following 2 services:

COM+ Event System

COM+ System Application

If either of these are set to disabled, you should double click them and change them to Manual startup.  Reboot and that should fix the issue.

No clue how to post a screen shot of the error and it only occurs at login.  However, I will try the driver reinstall.  Thanks for the help RaithZ and thinkpads user!

Commented:
What I posted above came from a dell community forum, where it looks like a few dozen people have had this same error.  Let us know how it goes, but I would suggest at least checking whether those 2 services are disabled before reinstalling the driver.

Is this a work laptop? And has the GINA login been replaced? GINA = Graphical Identification and Login.

No single answer was a complete fix - several of the responses were irrelevant

Commented:
I have actually resolved this.
- I went into MSCONFIG (from run),
- then clicked Services.
- I deselected the check box for Broadcom Wireless LAN utility. This may differ depending on your actual Wireless card manufacturer.
- Apply
- Rebbot

When I rebooted the error was no longer there. Some people say it is related to malware but this was a fresh install of O/S and drivers. All fixed!
