Nant failing with bad permissions on build server

Question

Total newbie question. I am trying to run a Nant script on a build server (very basic script, not doing anything), and it\'s failing with the error

This problem is caused by Windows setting the files' "Zone.Identifier" metadata in NTFS to "Internet" (or to another zone which you have to explicitly unblock to gain access).

To not cause file security metadata to be written when you copy files or, in my case, unzip from a zip file on a network drive, either copy the zip file to a local folder before unzipping it, as previously suggested, or run the "streams.exe" tool from Sysinternals to remove that metadata.

For example, if I run streams.exe on exe's in my Downloads folder:

streams.exe *.exe

Streams v1.56 - Enumerate alternate NTFS data streams

C:\Downloads\jre-6u27-windows-x64.exe:
   :Zone.Identifier:$DATA       26

Normally, streams.exe wouldn't display any metadata information if the files all originated from a local folder. If you do see these ":Zone.Identifier:$DATA" metadata (stored in NTFS as an alternate data stream), then you should also see an Unblock button in the files' Properties dialog.

To unblock the files in bulk, run "streams.exe -s -d *.*" from your problematic folder.
