Hello Cory,

Thanks and good luck !



well i appreciate the links to these knowledge base articles
but I think I have read every single article on this
it still does not answer my questions

Is there a problem when installing WSUS 3.0
on a MS Server 2008 using virtual iron
all the web updates have been done
I am using the windows internal database
I am using E drive to install database on
I have met ALL the prequesites
why does it error out during that part of the install
what is it trying to do when it fails
I have looked everywhere for some help on this
and tried everything everyone has mentioned
except tampering with the registry

You general help on the WSUS does not help either

Do you need anything else to help with this???
