OWA 2003 slow to authenticate

I've had an SBS 2003 server running for the past 4 years. It has Exchange SP2 and all the upgrades required by SBS Sp1, including Server 2003 SP1.

Lately, when logging in to OWA, it's very slow to authenticate after entering the username/password. It takes 1.5 to 2 minutes. Once it authenticates, it's OK. Also, once you've logged in once, if you log on again from the same computer, it's fine. It's just that initial authentication.

This happens from everywhere, even inside the LAN.
