Thank you all for your comments!
True, this is not a true hash but I needed something to title the article. I'll be more careful in the future.
I also use the DTSRUNUI property sheet which is much more flexible. There are too many options though to describe in a short article so forgive the omission.
The use of the /E option is another way to do this but is against our security policy to use trusted server connections. Several of you made a good point regarding the use of the "hash" is only good for a point in time run. If ANY change is made to the DTS package, the process must be re-run to get a new string.
Again, thanks for your input. I'll be writing frequently and welcome all your feedback!
