Dragging a robot into the archive and redistributing does not work.
This is general information applicable to most UIM versions.
Most likely, an INVALID OS is being used on the target Robot for the given package being distributed.
In general, when you create a probe template the distsrv probe uses the source OS for the OSType/OS fields in the probe package. The OS field filled in when you drag from a Windows 2003 server, is Windows 2003. This is not a valid OS name.
To correct this issue edit the probe package in the archive and change the OS to win32.
