ESX/ESXi 4.1 Unable to install windows 2008 r2 sp1 since the windows is unable to find the installation disk (missing drivers)

Issue: When tried to install the windows 2008 r2 sp1 on an ESX/ESXi 4.x host it failed to find/see the disk due since it did not have the proper drivers to see the VMware virtual disks.
note: the scsi adapter selected was lsi sas controller. Tried to inject the vmscsi drivers from the floppy image but they were not recognized as the proper drivers. []

Resolution: There are 2 different windows 2008 R2 SP1 images of different size but with the same build number. The correct working iso is of 3.02 gb and the one which does not work is of 2.6gb.
working iso from msdn/technet:

VMs unable to ping the host (ESXi/ESX 4.1) after upgrading from 4.0 U1

Background: The upgrade of the esxi 4.ou1 to esxi 4.1 has been made on 2 hosts of the cluster and after that some VMs in the host esxi 4.1 cannot ping the host and some VMs in the same host can ping the host but otherwise every other network communication between VMs to VMs and hosts to hosts is proper.
What worked : Remove the nics from the VM in the VM settings and add them back after a reboot.
What did not work: updating the proper ip information in /etc/hosts and /etc/sysconfig/network
restarting the management agents.
