I am considering starting over from scratch with my 2 servers. I can't
get patches to download and have a number of other issues with bundles
and such. I had thought that I could rebuild the one server (2k3) and
that would get patch working but it doesn't appear to be the case and
now that server won't even update to 10.0.1 so it seems to have been a
waste of time.

What I'm wondering is: Can I uninstall ZEN from my primary server but
keep the CASA stuff so that the certs are the same? If not, what will I
have to do to get my 90 clients communicating with the primary server again?
