Hello, I have two ISPs coming into my building, cable and dsl. The dsl is a backup line. Today the cable line failed and dsl picked up the work. however, nslookup, run on client or server, did not reliably resolve domain names. I have four forwarders set up: CABLE DNS1 DSL DNS1 CABLE DNS2 DSL DNS2 It seemed like since the first one failed that our DNS server did not continue with any other forwarders... I had to rearrange them: DSL DNS1 DSL DNS2 CABLE DNS1 CABLE DNS2 to get nslookup to work. Any ideas?
