An unexpected error has occurred and a Watson dump is being generated: Access t

Problem: When doing an Unattended setup for Microsoft Exchange 2007 using the setup.com command and switches you receive the following error message:

An unexpected error has occurred and a Watson dump is being generated: Access t
o the path 'X:\Setup\ServerRoles\Common\64' is denied.I had same problems as some of you indicated, where X is the drive letter for your DVD ROM drive.

I was installing Exchange 2007 from Production Copy DVD of Exchange 2007 Standard. Here is the strategy that I took after receiving the errors on multiple occassions.

Background:

We have 1 Win2K SP4 DC and 1 Win2k3 R2 DC, so installing Exchange 2007 from GUI is a NONO, atleast according to all the readings that I have done. So the only option is to install from command line using the Unattended setup (Setup.com) with various different switches. You can not use Setup.exe with switches.

When I was receiving the error message of:
"An unexpected error has occurred and a Watson dump is being generated: Access to the path 'X:\Setup\ServerRoles\Common\64' is denied.", I was installing all the roles at one time using the following command line:

setup.com /mode:install /r:h,c,m,t /t:"d:\program files\Microsoft\Exchange S
erver" /DomainController:DCNAME /EnableLegacyOutlook /LegacyRoutingServer:
LegacyExchangeName /EnableErrorReporting

and I would receive the error message.

I then tried to install all the roles seperately using the following command lines one at a time and every thing was successful.

Solution:

PS: Please replace DCNAME with the name of your Win2k3 SP1 DC and LegacyExchangeName with your E2k or E2k3 Exchange Server.

1. Client Access

setup.com /mode:Install /r:c /t:"d:\program files\microsoft\exchange server"
/domaincontroller:
