OWA ask for 2 user prompts with 2 mail servers in 1 domain

I just set up a second mail server in my domain and I did a transfer form the old server to the new server. When I access the account mailbox via OWA it prompts for user name and password for both the old and new mail server. Both server are running Exchange 2003 on Windows server 2003. Has anybody run into this before???
