We run SAMBA on a Unix box with case sensitive file naming (i.e. standard Unix usage). Relevant entries in smb.conf case sensitive = yes mangled map = (*.html *.htm) Using NT4 clients no problems are experienced in accessing files and navigating directories. Have a (small) client base using Win98SE which can map top level folders on the Samba server but cannot navigate. Problem is identified as Win98 sending filenames in upper case to Samba server which searches case sensitive and returns "not found". NT4 preserves case. Does anyone know of registry key to add/modify to cause Win98 to preserve case when using SMB? Win98 displays correct case when the initial mapping is done but requests for navigation (and/or properties) are incorrectly formatted. I have another (undesirable) fix available, which is to set the Samba server to be case insensitive but this leaves a gaping hole whereby two files differing only in case could be incorrectly retrieved (or worse the incorrect one overwritten). Any other suggestions as alternative to the two former?? Peter Tyers Tech Specialist Vic/Tas Network Services on secondment Phone 03 92536357 Mobile 0419 419 745 Fax 03 92536473
