Jeff - Disable service called 'DW WLAN Tray Service' through msconfig. This Dell Wireless tray service is set to automatically run at start up.Regards, h9ck3r.

Hello, Recently we purchased 160 Dell latitude 2120's, to use as classroom computers. I installed windows 7 pro x86 SP1, and ran sysprep/ghost to image the netbooks. After several weeks the computers would fail to boot , and choosing "Last known good configuration" would yeild "Windows Wireless Configuration" Notfication.dll is not registered and the program could not start. I can't boot into safe mode, I can't boot at all. I tried using Dart to analyze the dump file, it finds nothing. I also tried to register Notification.dll, it's not found. I have also tried to find this file on a known working system, it's not there. In addition these machines have been checked for viruses, we have a barracuda and we run Microsoft Security Essentials. This is a huge problem for us, and I'm out of ideas. Does anyone here have any suggestions? Thanks in advance! Jeff

I think you might be on to something. I'm in the process of building a new image, with the DW WLAN service disabled. However, you need to go into services and disable the service even after disabling it in msconfig. I'll post back when I get the new image and push it out to see if this resolves our issue. Thanks!

sure go ahead...Regards, h9ck3r.

is this error coming up on all the laptops ???Regards, h9ck3r.
