NT warns you when you create a share name which is inaccessible to DOS-based
PCs. What you may not be aware of is this includes DOS, Win3.x, Win95 and Win98.
Clients with these platforms can not access shares with names greater than 12
characters. NT clients have not problems with such long share names. The length
limitation for DOS-based clients is a design problem and will not have a fix
(except upgrading clients to NT workstation).
Bottom-line: don't ignore the warning about inaccessible share names if you
have DOS-based clients such as Win95 or Win98.
