I have good reasons for wanting to use 2012 R2, but this is pretty frustrating. Are any of you wonderful folks on Neowin aware of problems like this? Or, even better, solutions? :D

This is kinda driving me nuts - network speeds are clearly okay on the whole, so it leads me to believe I just have something configured incorrectly - Windows Server 2012 obviously doesn't come configured for workstation use out of the box, so I'm thinking I probably have some issue with security policies that I'm just not aware of. For what it's worth, the behavior is also time sensitive - if I don't do any web browsing for awhile, even pages on the same domain load slowly again. Firewall on/off also makes no difference. At first the peculiar issue with domain names (pages on the same domain load fast after the initial slow loading) lead me to believe there was a problem with the DNS cache, but the behavior is unchanged by DNS cache flushing. Now that I'm running Windows Server 2012 R2, I have this problem. I also ran the Windows 8.1 Preview on this machine with no issues. This machine had no problems when it ran Windows 7. Other computers on the same wireless network have no issues, but these machines are running either Linux or Windows 7. I have confirmed that this problem occurs for Chrome, Firefox, and Internet Explorer. Strangely, download speeds and speed tests reflect my connection (about 20 mpbs down, 5 or so up) accurately, and the problem is confined to web browsing. loading takes ages, but further Google result pages load quickly). If I restart the browser, the problem is back (i.e. Initially loading a domain takes a very long time (about 20 seconds), but other pages on that domain load at an appropriate speed. I'm connected to my router wirelessly (using a Linksys WMP54G NIC with Ralink RT61 drivers), and web browsing is initially very, very slow. At the moment I'm running a copy of Windows Server 2012 R2, but as a workstation. I cannot seem to find any solution to this problem, even with extensive searching. I'm returning to the IT forums, admittedly, out of desperation. Hi Neowin! I haven't posted in quite some time, but I still lurk.
