D3Std/WinNT4: Invalid address in DCC.DLL

When starting Delphi3 Standard (German version) under WinNT4 as a
non-administrator-user, I encounter an
>Access violation at address xxxxxx in module 'DCC.DLL': Read from

address 0000000< after a while.
I don't have to do anything but waiting to get that error. Delphi
doesn't die, but is unuseable
Does anyone know this problem and has a solution?
Thanx in advance.
