Strange behavior when try to access share on W98 client if nobody is already logged on

Hi,

I have a Windows 98 Se clients connected to a Domain controler Windows
server 2003
The microsoft clients are set to connect on a domain.
The clients are also set to retreive users and groups list from domain. One
share is made on the W98 clients and domain admin have full access on it.

I f any user are already logged on the W98 client, domain admin can access
the share and everything works well.

But if the client is not logged (the machine are at the loggin window)
domain admin receive an error message and cannot access the remote share.
Also after this nobody can log on the machine. We have to reset the machine
to have access to it again.


Thank you for any help
