For ESX and ESXi 4.0 hosts

The Scsi.UWConflictRetries parameter for ESX/ESXi 4 Update 1 hosts have a default value of 1000. This increases the time spent enumerating LUN and VMFS volumes.
To resolve this issue and to speed up the boot process, modify this value to 80.
To modify the Scsi.UWConflictRetries parameter from the GUI:
  1. Go to Host > Configuration > Advanced settings.
  2. In the Advanced settings window, select SCSI.
  3. Change the Scsi.UWConflictRetries value to 80.

For ESX and ESXi 4.1 hosts

To resolve this issue in ESX/ESXi 4.1 hosts, you must modify the Scsi.CRTimeoutDuringBoot parameter from the GUI.
To modify the Scsi.CRTimeoutDuringBoot parameter:
  1. Go to Host > Configuration > Advanced Settings.
  2. Select SCSI.
  3. Change the Scsi.CRTimeoutDuringBoot value to 1.

Unable to uninstall the old version either.

This is an issue with Microsoft Windows Installer and does not affect all Windows 2008 systems. The problem can occur when the original install path from the older version of VMware Tools is invalid

To correct this issue, you must perform a forced uninstall and re-install of VMware Tools.

To uninstall and re-install VMware Tools:

1. Right-click on the virtual machine.
2. Click Guest > Install/Upgrade VMware Tools.
3. Open a Console to the virtual machine and log into the guest operating system.
4. Click Start > Run, type cmd, and click OK to open a command prompt in Windows.
5. Change the drive to your CD-ROM drive. For example, D:\.
6. Type setup /c and press Enter to force removal of all registry entries and delete the old version of VMware Tools.
7. In My Computer, double click the CD-ROM that contains VMware Tools.
8. Select setup.exe to install if Auto-Run doesn’t start.

To fix it, add the following line to the /etc/vmware/config file in the VMware ESX Service Console:

” vmauthd.server.alwaysProxy=TRUE “
