There is a lot of posts on http://forums.iis.net related to network performance.  Actually, there was two today!.  The problems can be different, but the common thread seems to be network performance.  Windows Server 2008 (and R2) enabled a new network feature by default which has been referred to as “Scalable Networking Pak”.  Some people refer to the feature as TCP Chimney Offload.  Either way, in my experience this feature causes more issues than it solves.  If you are having a network related issue or performance, this is a easy setting to check and verify if disabling portions or all of them can resolve the issue.

I strongly encourage test these changes in a non-production environment before making changes to your production systems!

I’ve seen a few posts asking “How do I harden my IIS 7 machine”.  Frankly, Microsoft IIS Team has done an excellent job making a IIS Admin’s life much easier and doesn’t require nearly as much as IIS 5 days ?  Here is a thread though that discusses some other techniques.  Thought I’d pass it along.

I had a person contact us that used MailEnable (http://www.mailenable.com).  They were looking to use IISLogs 2.0 to manage their logfiles.  Here is an article discussing this more.

UAC  was introduced in Vista and in my personal opinion was not done very well.  With the introduction of Windows 7, Windows Server 2008 R2, Microsoft did a better job with UAC.   The jury is still out if it’s universal setting that stays enabled.  ?  I wrote an article discussing how to configure IISLogs 2.0 with UAC enabled.

I had a co-worker ask me about using WinSCP for automating SFTP puts to a remote host.    I personally have never setup a SFTP server nor use SFTP client (or it’s been a while :)).   There is a thread on http://forums.iis.net that has great information.   I included the link to the post.  The one thing I used for my test was FreeFTPD, which was real straight forward.  It seems to support NT Authentication.  I tried a couple of times, seems to be lacking a easy feature to extend to an entire Active Directory environment.  For my testing, it was very good.    I setup on Windows Server 2008 R2 with no issues.  I’ve setup FTP over SSL too and it’s a different solution.  Depends on your requirements.
