By the way...

Try following: - Right click powershell and “Run as Administrator”. This worked for me because my user already had dbo rights to SharePoint_Config database.

Go to Central Administration>Upgrade and Migration>Convert License Type> check the current license under Current License. Enter new key to upgrade to new license type.

At first, I thought I cannot connect VPN before logging in to Windows Server 2008 R2. But then I figured out that there are a couple of things one must do to use the dial-up connection before login. 1. Create a VPN connection and during connection setup, make sure you have selected “Allow other people to use this connection”. 2. After log-off from current user, hit “Switch User” button and look at the Right Bottom of the screen where you should see a button. Click that and it will ask you VPN credentials. Enter credentials and that’s it! You are in!

To install and enable WiFi on Windows Server 2008 on Dell Studio L501X, I had to follow the steps below: 1. Go to  Start > Administrative Tools > Server Manager… 2. In the Feature Summary, click Add Feature, and check “Wireless LAN Service" and Install it. 3. Download WiFi driver from Dell’s site OR locate it on your “resource disk” comes with the laptop. Mine was “R273603” driver for the adaptor. 4. Well, running the driver package won’t install it, so just let it extract it to “c:\dell\drivers\R273603” folder (or your driver name folder). 5. Now go in “c:\dell\drivers\R273603\drivers\” folder and execute “DPinst64.exe”. 6. RESTART the system and should be all set!
