New Notes Workstation Installation

Installing Notes 6.01 on a new workstation. After installation when filling in setup screens it gets to User Name & Domino Server Name dialog. Fill in info. & it tells me Certificate Has Expired for the user.id. It never asked me where to look for the id file but see it is checking the Domino Directory. When I check the properties of the user.id in her person document it does not expire until 2005. What am I missing???

Any input or help is as always appreciated.
