I am unable to see the tree in the Application Explorer window on most
workstations. When I log into a Terminal Server as the same user and the
Terminal Server has the ZfDAgent installed, it works fine. The ZfDAgent
in all cases is from ZEN6.5sp2. The Application Explorer icon on the
desktop that isn't working is different. For lack of better terminology,
the icon has the "connecting" bar on each side. I have recently re-
entered the Proxy Username and Proxy Password entries in the registry on
the Middle Tier server. I've uninstalled and reinstalled the ZfDAgent on
the workstation with no change. The Middle Tier authentication seems to
work fine and I can authenticate to the Middle Tier using an LDAP
browser. On a side note, I am unable to reinstall the Middle Tier server
on this server and get the following error...

Web.w2K files NOT successfully installed because files are marked READ-
ONLY or files are IN-USE on <server> at E:\
Error: There was an error installing ZENworks Desktop Management on
<server>. Error: An error occured during file copy or configuration.
See above for more details and be sure that no ZENworks Desktop
Management files are open or locked.

As mentioned before, the ZfDAgent is working fine on some pc's (Terminal
Servers for sure) but not on the few workstations I've tried so far.

Thanks for your help,
