Using Windows 2008 Standard 6.0.6002 Service Pack 2 This webserver used to have both a website and a SQL 2008 instance on the same box. Site would often become unresponsive. We then setup a separate server for the database on 2008R2 The issue is communications between the webserver and the database server. This is done over a private LAN. When first started everything is zippy fast but over time performance degrades. After a reboot using Query Analyzer from the web server I can run a query selecting the top 1000 rows of the product table and results will return in less than 1 second. Most often around .4 So let the server run for a while and time of this query slowly creeps up. Also it takes longer to transfer files between the servers over time. Reboot the server and all is good again. I would like to eliminate this issue and browsing around I see a few suggestions. Is this a common issue. This is not an application issue I do not believe since I am testing strictly though query and file transfer. So far the only thing I have done is disable IPv6 on the web server network. Other sugestions I have seen are From a Microsoft Windows Command Line, disable Autotuning as follows from the Windows Command Line: netsh int TCP set global autotuning=disabled From a Microsoft Windows Command Line disable Receive Side Scaling (RSS) as follows: netsh int TCP set global rss=disabled From a Microsoft Windows Command Line disable TCP Chimney Offload as follows: netsh int TCP set global chimney=disabled Disable IPv6 for any network adapters connected to an IPv4 only network. To disable IPv6 perform the following steps: Click Start , Settings , and Network Connections . Right-click the network connection and click Properties . Disable the checkbox next to "Internet Protocol Version 6 (IPv6)" and click OK . All of these options are enabled by default in Microsoft Windows Server 2008. Note : Ensure that TOE is disabled on the on-board 5709 NIC ports. This is the default setting. ------------------- netsh interface tcp set global autotuninglevel=disabled netsh int ip set global taskoffload=disabled Are these worthwhile to try? Any other information needed please let me know. Thank you for any suggestions.

Suggestion: New drivers for Intel network adapters ?! I had a lot of problems with a server - Intel mainboard S32xx series, two built in Intel network adapters, originally insttalled drivers from the mainboard OEM DVD. The problems was solved with newer drivers for the network adapters.
