why is vpn slow when establishing secure connection?

Hi I have two win2k servers in the same active directory domain with single nic's configured for vpn access. They are both configured the exact same way but when I try to connect to the first using a winxp pro computer vpn connection it takes about 60+ seconds to connect, the other takes about 2 seconds. The problematic one displays "establishing secure connections to x.x.x.x" for about 60 seconds. After it finally resolves it works fine. Event logs don't seem to indicate any problems. I've also tried using a dns name and get the same result. What might be causing the delay? Thanks, Aaron
