Microsoft Remote Connectivity Analyzer

Life was simple with Exchange 2003 but as life goes on, newer versions of Exchange have appeared and what was once simple has become a bit more complicated.

One of the first gotchas you notice with Exchange 2007, 2010 and 2013 is the increased security and the challenges of connecting to Exchange remotely.  One tool that I find to be invaluable is the Microsoft Remote Connectivity Analyzer which can identify various issues with your configuration.

Apple Keyboard Shortcuts

I bought a Dell tablet and I really liked it except for when I really needed to get some work done which is when I started hunting for a bluetooth keyboard.  Since I'd already purchased the nifty aluminum keyboard from Apple for my iPad, I connected it to my tablet.  All was well in the world until I started looking for my favorite Windows keys.  Stumbling upon this site, I found that 'some' of the combos work, others not so much but I still think it's helpful nonetheless.

The one that really drove me nuts was the Windows delete key which can be had by simultaneously holding the CTRL and D key.

Remotely Enable RDP

Did you forget to enable RDP to only discover your mistake after you were remote to the machine?  Me too.  If you can get on the network, you can launch the registry editor and then point it to the remote workstation.  Change the following:

HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\fDenyTSConnections

Set the value from one to zero.

One Time Email Address

You go to a web site, you want to download something and you're required to give an email address, possibly to confirm you're a real person.  In most cases, I create an alternate SMTP address on my mailbox, acknowledge their message and then delete the address from my mailbox.  As an alternative, this site enables you to create any email address and receive messages which can be viewed through their site.  Be warned, EVERYONE can access this email so I would only use it in cases when the received mail is meaningless.

Disable Windows 7 Firewall

Really not much to add other than I sometimes feel the need to remove the Windows Firewall from the equation when trying to troubleshoot a problem.

Launch a command prompt as the admin (right click, select run as administrator) and enter the following:

netsh advfirewall set AllProfiles state off
