on Netware 5.x and 4.x normaly it is:
Error: "Login-4.21.14-430: The following drive mapping operation could not be completed.
[ROOT s16:=.mymap.myorg:\. The error code was 8875."
Error: "Login-4.21.15-430: The following drive mapping operation could not be completed.
[ROOT s16:=.mymap.myorg:\. The error code was 8884."
Error: "Login-4.21.14-430: The following drive mapping operation could not be completed.
[ROOT s16:=.mymap.myorg:\. The error code was 8804."
Error occurs when executing a MAP command from a login script of a 4.11 File Server using Novell Client for NT v4.51.1029.
--------------------------------------------------------------------------------
Cause
The command in the login script that returned the error above was:
MAP ROOT S16:=.MYMAP.MYORG:\
The syntax used in the MAP command in the login script contained a colon ":" (the one after MYORG in this example) but the directory map object referenced in the map command did not point to a volume root. Instead, it pointed to a subdirectory below the root. The NT client is behaving correctly to produce an error in this situation.
NOTE: With the Novell Client for WIN95, executing the same map command as above, will not produce an error, regardless of whether or not the directory map object points to a volume root.
--------------------------------------------------------------------------------
Fix
Unless the directory map object referenced in the MAP command actually points to a volume root, do not use a colon ":" (the one after MYORG in this example) in the syntax of the map command.
