http connection failures after installing C2960G switches
I have seen this at two sites now: after migrating the site T1 to 10-Mbps Opt-E-MAN and replacing old 10/100 switches with 10/100/1000 switches, users frequently get http connection errors. The error goes away if the user reloads the page--sometimes they have to reload more than once. They never had this problem before.
I thought it was due to the large number of 5-port desktop switches infesting the networks (I'm getting rid of them as fast as I can) but it happens even on a PC directly connected to one of the new GigE switches. It does not happen when accessing internal web pages.
It looks like a DNS failure -- but nothing has changed in our DNS setup, except that users have a fatter pipe to our DNS servers.
Any ideas? How do I explain to users that giving them a faster network breaks their web browsing?

Found the problem : I'm an idiot. I set the default route as GigE0 -- the int itself. It worked, but the arp table was enormous! I reconfigured it to use EIGRP and all was well. Embarrassing, but I'll leave it up for the edification of others.
