Outlook 2003 remote to Exchange 2003

I have a remote outlook 2003 client that can't connect to the exchange server 2003, even though another client same configuration can.  Also, when I checked the ports everything is ok.  The only error that I can find is a certification problem.  Any help would be appreciated.

can you check that the name the certificate has is the same as the FQDN or short name you use in your DNS server i.e

if the certificate is mail.organisation.com then your address you connect to should be mail.organisation.com and this should be in your DNS.

I know you said it works on other machines, so either 1) this machine cant resolve the address, 2) the address of the server this client connects to is different or 3) the client cant verify the certificates authenticity (i.e the certificant authority isnt on its trusted list).

Also.. check the time on the client is correct :).
