I have done a few CRM 2011 installations and although the first part of the installation actually starts with making sure the servers are 64 bit and have enough power, the next stage is begging the IT person to give you domain administration privileges so CRM can create some active directory groups.
You have another small leap which is to log onto the clients servers and spend a few times trying to type in the tricky passwords.
You are now ready to set-up the prerequisites of SQL server 2008 installation (probably configuring reports server as well) and adding the pre requisites for the CRM server and making sure IIS is turned on and various other bits and bobs.
One big tip here is to make sure the SQL Server 2008 installation media is either in the DVD drive or available on the server otherwise you won’t be able to configure the SQL Server 2008 installation.
These is a critical part of the install, things not turned on and installed now can cause you hours of head scratching.
Luckily someone absolute hero
has created a fantastic picturetastic prerequisite installation guide. The whole installation guide is fantastic and you can find it here.
