I have remote users that are using Citrix 8.0 client. When we install the
ZfDS 6.5 agents, Citrix client no longer functions. Reinstalling Citrix
client fixes the problem.

What I would like to know is what is ZfDS 6.5 doing that breaks Citrix
client? If I know that, I can fix it with the ZfDS install and not have to
reinstall Citrix.

(I would re-install Citrix via ZfDS, but Citrix is vital and the timing
just isn't right.)
