Thanks for the comments My answers below. Yes both DHCP servers are on the same broadcast domain at the hub site. I have two helper addresses on the same interface(remote site, thinking redundancy, but it may not be as effective as I thought it would from your comment). What's weird is that when I manually release/renew the lease from win95/98 machines, it works just fine. It's just not automatic. The machines at hub site does this automatically without any problems.
