Within Windows NT Explorer, after mapping a network drive to a Directory File System (Dfs) share, the drive letter for the associated connection does not appear in the drive listing. Refreshing the window causes the connection to appear in the drive listing.
Also, Dfs mapped drives may fail when setting them to the current drive from a command prompt.
This problem occurs because the Dfs connection type is not automatically refreshed.
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update. For information on obtaining the latest service pack, please go to:
