Not able to PING Windows Server 2008

Most of network issues might be easily overruled by performing a simple PING test to the problematic device or to specific network devices.

Not receiving a PING REPLY does NOT necessarily mean that there is a cabling or IP Addressing problem, simply because PING could be blocked either on the receiving end, on the sending side, or on various network devices between those two points. This is mostly done due to security related issues involving PING (or better say – ICMP, the protocol behind PING).

In Windows Server 2008, the default setting is that the windows Firewall is configured to block ICMP.

In order to configure Server 2008 to allow ICMP replies, follow these steps:

Enable ICMP Replies via the local Command Prompt
On your Windows Server 2008  machine, at a command prompt, type the following:
 
netsh firewall set icmpsetting 8

This will allow you to ping the Server Core server from a remote machine, and receive a reply.

You can always run the following command in order to disable this option:

netsh firewall set icmpsetting 8 disable

SQL Azure Error - 40544

If the size of your database reaches its MAXSIZE you will receive an error code 40544. You cannot insert or update data, or create new objects (such as tables, stored procedures, views, and functions).To fix this issue either increase your database size or delete data. For increasing/decreasing SQL Azure database size, you can use this command on the Master database. Alter DATABASE database_name MODIFY (MAXSIZE = {1|5|10|20|30… 150}GB); example: ALTER DATABASE sampleDB MODIFY (MAXSIZE = 5gb);

Hardware DEP (Data Execution Prevention), NX, XD & EVP

A processor can be instructed to designate regions of memory as non-executable. This means that the memory can be used to store reference data to be read and written, but that the processor cannot treat the contents of the memory as program code to be directly executed. Intel calls this capability in their newer processors XD for “eXecute Disable” and AMD refers to it as NX for “No eXecute.” AMD's marketing materials also sometimes refer to this capability by the term EVP for Enhanced Virus Protection.
As a hardware capability of modern processors this addition is important, but its use depends entirely upon support from the operating system. So when Microsoft introduced support for this into their operating systems, they termed it Hardware DEP for Data Execution Prevention. Support for hardware DEP was introduced into the 32-bit versions of Windows XP with Service Pack 2, into Windows 2003 Server with Service Pack 1, and has always been present in Windows Vista. Hardware DEP does …
