Windows 7 Machine Can't Connect to Network Share

Thunder plugin for iNews doesn't work in Windows 7 because Windows 7 machines can't connect or map a drive to a network share folder on a machine not in the domain.

Click the Start button and type secpol.msc in the search function.

Browse to "Local Policies" -> "Security Options".
Now look for the entry "Network Security: LAN Manager authentication level" and open it.
Click on the dropdown menu and select:
"Send LM & NTLM - use NTLMv2 session security if negotiated".
Apply the settings.

HP Pavilion dm1 Webcam Not Working After OS Change

After changing the operating system from 64-bit Windows Home Premium to 32-bit Windows 7 Professional, the internal webcam would not work. The HP MediaSmart Webcam software or Skype would give a error message saying:

HP MediaSmart Webcam cannot connect to your webcam (HP Webcam-50).
Skype can't connect to your webcam.

The drivers for the webcam were installed from HP's website and the Device Manager showed the webcam as working.

I found this info:

1. Open regedit
2. Browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{6BDD1FC6-810F-11D0-BEC7-08002BE2092F}\0000
(This should be the registry key for your webcam. If it is not, it may be at 0002, or 0003, etc.)
3. Add a new 32-bit DWORD value called "UvcFlags"
4. Set the data for this value to 10 (10 Hex, 16 Decimal)
5. Restart your computer and test the webcam


There was also a 32-bit DWORD called "KS" with a value of 1 on the original 64-bit Windows Home Premium installation.

After adding UvcFlags & KS and restarting, the webcam works fine now.

I have a 2nd HP Pavilion dm1 that I did the same OS change to & it had no issues with the webcam.

HP Pavilion dm1 Factory Image Restore After OS Change

After doing a clean install of 32-bit Windows 7 Professional on a Pavilion dm1 (dm1-2010nr) - replacing the original 64-bit Windows 7 Home Premium - I needed to restore the machine to its original OS. I did the clean install by formating the partion that contained the original OS, but left the others intact so that I could use the factory restore partition in the future. Unfortunately, I could not boot to the factory restore partition after the OS change. It ignored the F11 press during bootup (It actually displayed on the screen F11 - System Recovery, but then went on to boot Windows anyway). I had to go to the Windows Computer Management console (Start menu & search for computer management) & go to the section called Storage & then click on Disk Management. The Recovery partition shows up as the D: drive. Right click on that partition & choose "Mark Partition as Active". On the next reboot, the machine will boot into the recovery environment.

HP Netbook & Verizon HP un2420 Broadband Wireless Module

We purchased a number of HP Pavilion dm1 (dm1-2010nr) netbooks from Verizon which came with 64-bit Windows 7 Home Premium. We need 32-bit Windows 7 Pro for our software. After doing a clean install of 32-bit Windows (formating the partition with the original Windows install, leaving the other partitions alone), & installing the drivers & software from the HP website, the HP un2420 Wireless modem would not connect to Verizon using the VZ Access Manager software. The VZ Access Manager software recognised the card as an HP un2420, but couldn't configure it. Instead of displaying Mobile Broadband (EV-RevA), it would show an error message "Network registration denied". The Options menu in VZAM did not display an Activation option. Even restoring the machine with the Factory Image Restore did not restore functionality of the wireless card.

To resolve this, open the VZ Access Manager and go to Option>Network Selection & change the Network Mode to CDMA. Click Yes to the popup window that says, "Are you sure you want to change the network mode?". It should then be able to complete the configuration & display the "Activation" option under Options. Click on Options>Activation and complete the activation process.

BTW, pressing CTRL-T while in VZAM will bring up a terminal window that can be used to test whether the modem is working. The modem should respond to an AT command with OK & it should return a bunch of info to an AT&V command. ATDT#777 should return something like CONNECTED 3100000, not NO CARRIER.
