Slow to establish connection on all browsers on Windows 7
HI, I have been searching everywhere and tried numerous amounts of troubleshooting and am still stumped. I have a Virtual Machine running a fresh install of Windows 7 Enterprise 86bit, 1GB Ram, Intel Xeon CPU . The internet connection is fine, but the browser (tried Firefox, IE8) is slow to establish a connection on ALL new web pages. Once it loads after 10-25sec lag, the speed is fine and browsing fine. I have tried the following: - Removed IPv6 - Allowed only NTLM connections (trying to connect to a webpages on different infrastructures i.e NT4, Windows 2000, Windows 2003, XP) - Turned down internet security to low - Clear cookies, temp internet files, added website as Trusted site - No add ons installed or Anti Virus software, turned OFF windows firewall - Flushed DNS and confirmed DNS is caching entries - I can successfully 'tracert' all websites with no lags - I can ping the DNS and the default gateway - Checked Local Group Policy and nothing as a default seems to be limiting this - I confirmed the website can be reached from the same network at normal speeds from WIndows 2003, XP - Turned of Auto-Turning (turned back on with as it had no effect) - Turned off ECN If anyone has anymore suggestions it would be great. There is no issue once the page loads, but getting the page to load on any new internet window is ridiculously slow. Thanks

1. Are in workgroup or active directory? 2. If the problem is in ALL browsers, then my guess is that the name resolution plays the role. What DNS setting (NIC) do you use? (Try to insert IP address of web server instead of name and see if there is any change in delay.) 3. If 1 or/and 2 gives no resolution, the use process monitor and network monitor to find where is the longest delay (The forme is from Sysinternals, NM is either theof Microsoft or free Wireshart) 4. In every troubleshooting a look into event logs is the very first step as well as resolution possible problems here. 5. Try to do statistics between the response time and how far the server is. Chances are, that there is larger delay on the route.... 6. Not all changes that you refer to are bound to this problem. 7. Do your "forensic" with disabled add-ons and only one browser active.

Hi, Adding to Milos, please also let us know what platform do you set this virtual Windows 7 on, Windows Virtual PC, Hyper-V or others? And, please double check your virtual machines network settings. If you use NAT, please change it to Bridged Adapter and see how it works. Hope this helps. Jeremy Wu TechNet Community Support
