Hi Steve,
This is really weird because I have created numerous companies over the years and never had this problem.
I just retried the operation on a local drive and the only way to make it work was to do your trick.
I have done a full backup of one of our systems including an integrity check and then tried to create a new data set once again but with no success.
What do I need to fix so that this issue is corrected? i would hate to be caught in a position down the road where we cannot add data sets and then we need to get the heavy weights in to "tap the fridge in the right spot"!
<grin>...
As always, thank you and,
Cheers, JK
