Avocent DSR 4020 Configuration Guide - Using the Serial Port like a boss

How to Configure The Avocent DSR 4020 The Avocent DSR 4020 is a legacy/old skool keyboard video, mouse (KVM) server with a network management interface, and a DB9 serial port based management interface.  Unfortunately, the remote console feature requires Java JRE 1.6. (6u45)  It has 16 ports.  The bank of RJ45 jacks on the back are NOT network jacks, instead you need to use DSIQ dongles to connect them to video and USB ports on your servers.   You can also get DSIQ dongles with PS/2 connectors.  Both network and serial interfaces can be used to configure the KVM.  The serial interface is a closely guarded secret.  If you bought a used KVM from ebay, you can use Serial to reset and wipe out the password.  The Avocent manuals do not explain this port.  We will explain how to use it.  If you need assistance with your Avocent, call us, we can help.  Consider hiring a real IT pro to properly install your KVM.

MSSQL+CRM2011 FUD: The instance name must be the same as computer name

while installing MS CRM 2011 or 2013 you get this stupid message and all activtiy grinds to a halt:
"The instance name must be the same as computer name" it happened because you took a virtual machine template and cloned it, and renamed it, and then started to use it immediately without any consideration of the SQL server within.
You have to rename the MSSQL server.
use these commands one by one: in the master database
to query the binds  SELECT @@Servername
to drop the invalid name  Sp_dropserver 'OLD_SERVERNAME'
to add the correct machine name  Sp_addserver 'ACTUAL_MACHINE_NAME',local 
These command are case sensitive, so be careful.  Finally, restart the MSSQL services, and close and reopen the MSSQL studio.
This KB tidbit applies to MSSQL 2008 R2 Enterprise, Windows Server 2008, MS CRM 2011
