Solidworks 2013 is being prompted for the Vault server login 2013.

Only one of my user when logging into Solidworks(2013) is being prompted for the EPDM Vault(2013) server login.(And it doesn't recognized the vaild vault server).  He is able to open via EPDM explorer without issue.  Any help or suggestion is very much appreciated.
