VERY VERY strange one here. One ISP Time Warner Telecom. Two T-1 Lines. Out of their data port they hand off to me. I have a Zyxel Zywall 2 router in place. I setup so that the public x.x.x.2 goes to the 2000 server and the public x.x.x.3 goes to the 2003 server. These two different servers server two different networks with two different companies. Both servers are running exchange and DNS. The public x.x.x.4 address resolves to the workstations on the internet. From the router output to a switch and then to the servers and workstations
With that said we have problems with any yahoo website. Finance.yahoo.com , travel.yahoo.com, movies.yahoo.com and sports.yahoo.com. Any of those are just so slow it takes five minutes to finally load and then it doesn't load pictures. What is very strange is that before about 9:00 AM it is smoking fast without problems and then it goes to nothing. Sometimes it is fast but there isn't any consistent pattern except that it is slow and frustrating.
Time Warner tells me we have a DNS problem. Both 2000 and 2003 DNS servers forward to their DNS servers. All clients point to their correct servers for DNS. Cnn.com or msn.com or msnbc.com are smoking fast.
I have heard about EDNS and I dumped that. Still having a ton of problems. Do you think it could be throughput with the router? Thanks,
