Chris -
I have seen this lag as well in dial-up connections. My guess it is simply a NetBIOS issue over a dial-up connection. Windows is using NetBIOS to find and display these connections. KiX is simply providing an easy method to have Windows perform this step. KiX script execution speed is not material to the ability of a Windows system to find/display drive mappings.

Since you state the mappings are taking effect, no real problem exists here except for the time delay. To my end users I would say: Yes, it is slower because you are on a dial-up line, nothing will speed this process up except the end-user having a faster connection to the internet (or ISDN dial-up lines), you will have to learn to live with it, and dispose of this issue.
