Re: [Condor-users] Windows encrypt on disk for execute nodes ofjob files

     I just did some testing on W2K server which is what I am running. It looks
like by default Windows is adding the administrator's key to the keyring for all
encrypted files. This will mean that administrator will always be able to read
encrypted files. From the other discussions on this I would guess that XP
doesn't do this. But it looks like it was working all the time.

Thanks again for your help.

Cheers Paul

I'm not Todd, but I'm pretty sure that he was referring to EFS support.

No, Windows 2000 should work fine. Here's two things to check:

1. Verify that you've correctly spelled


in your config file, and that this setting is reflected on your execute

2. While a job is running, if you can get an administrator shell
started, you should find a hidden Desktop.ini file in the execute
directory (the dir_#### directory underneath EXECUTE). The file should
contain two lines:


if the file isn't there, or doesn't contain those two lines, check the
starter log for error messages.

Assuming all goes well, you should be able to do a 'dir' on the execute
directory, but attempting to read the contents of the files should fail
with Access Denied. Only the person that created the execute directory
(in this case, probably condor-reuse-vm1) should be able to successfully
read any of the files.
