Customer using Active directory integration function in 4.1. the user logged in is DOMAIN/user_name, and since the user is not in the sudoer file, they can not view logs

You can add AD groups into sudoer file
for example, you have a domain called "MYDOMAIN" and the group call "ESX Admins" (or MYDOMAIN\ESX Admins)
you add this under group %wheel:
%MYDOMAIN//ESX/ Admins ALL=(ALL) ALL
Note: if it did not prompt for password, you may need to restart the server, and everything will work from here)

Some times customers may want to change the virtual hardware version back from 7 to 4, there is a way to do this

the first is the VM's vmx file
the part you need to change is:

virtualHW.version = "7" you change this to
virtualHW.version = "4"

No need to change config.version = "8" since ESX 3.x already using this version

Next what you need to change is:
scsi0.virtualDev = "lsisas1068"

this is default for version 7 of the virtual hardware. Version 4 will not understand this virtual controller

You can change to
scsi0.virtualDev = "lsilogic"

The next step is change the .vmdk file of the VM (pointer file)
ddb.virtualHWVersion = "7"

you need to change this to
ddb.virtualHWVersion = "4"

and after that, you should able to power on the VM as hardware version 4

(please note, this is not supported by VMware)
