I have just created a 2000 server and it was working well. This company uses Quattro pro 4 for DOS in a BIG way for their process mgmt, inventory control and timesheet entry.
The problem occurred when I added security to a directory and suddenlyQuattro pro thinks the directories are now files (leaving them inaccessable). Removing the security I added had no effect. Apparently there is some kind of attribute that is attached to directories when security is applied that makes them inaccessable from old DOS programs. The only way I found to reverse the problem was to copy the directories in question across the network to a workstation, then back to the server and apply NO security. When security is applied the directories become inaccessable again but ONLY to these old programs that are so CRITICAL to the operation of this company. Has anyone heard of this problem? Microsoft was no help. Is there a way to change the directory attributes back to their defaults without the copying process I described? An answer to the latter question is worth a 1000 points!

If they are dead set on using such an old app then it would be better to maintain the files on a FAT partition. Even though W2K attempts to simulate the DOS environment for the app it is still implementing NTFS file structure and trying to convince the app it is FAT. If Quattro insists on FAT specific formatting on its file structure then W2K is probably not convincing it otherwise.

Remeber that although MS claims backward comp. they are really pushing away from DOS and W2K is 'less forgiving' of old 16 bit apps.

Previously this system was run on a Netware 4.11 file server with no issues. Converting to a FAT partition would allow me share permissions control only. Thanks for the info.

You should be able to access the directories from a Windows NT 4.0 Workstation and apply Everyone with full control permission.

I have changed the permissions to everyone which is how it was originally. This is not a permissions issues but changing the permissions causes the directory attribute to change! Thanks.
