NFS and Service for Unix 2

[Reuber]

Hi
When I set Service for windows 2.0 on our W2k server to lower case letter (changes in Registry), I only can see files and dirs saved original in lower case letters with our hp ux 10.20 over nfs. upper case named files are not found:

ls on nfs drive looks like this:

./source not found rem (orig. saved = SOURCE)
./util not found rem (orig. saved = UTIL)
drwxrwxrwx 2 root root 64 Feb. 14 13:03 daten

whats wrong ??
regards reuber
