Subject explains it all. Built a brand new NW6.5sp2 server with nothing
optional on it for a new database server to replace a tired old server.
The install fails with the following message - never have I seen such a
poor install debug log:

[Local Workstation]
Pre-install steps completed successfully
ZENworks Desktop Management files copied successfully.
Post-install steps completed successfully
Install successfully completed on Local Workstation. However, you may
wish to verify that all installed services are configured correctly.

Pre-install steps completed successfully
XML Proxy Server components NOT installed on DHSZDB
Error: There was an error installing ZENworks Desktop Management on
DHSZDB. Error: Error copying files to server. Be sure that no ZENworks
Desktop Management files are open or locked.

How can any files be open on a server that has NO Zen on it at all?
