Problem: Intermittent Authentication / Authentication problems for specific users

Solution: In my experience, Kerberos (the default authentication protocol for Windows 2000 and later) is the cause. Firewalls, Proxies, and possibly other network components can block Kerberos tickets causing authentication problems for certain users, intermittent authentication problems for all users, and authentication problems in certain circumstances (i.e. VPN).

While I'm certain that many Microsoft advocates, security advisors, and other administrators would sneer at this advice, I suggest you just get rid of Kerberos authentication on your web server. I want the most secure solution that works, but if it doesn't work, screw it. I rarely have problems with NTLM. The following command will get rid of it, but you will need to open a command shell, and navigat to the admin scripts folder (c:\inetpub\adminscripts in windows 2003 and IIS 6):

Problem: IIS Logfiles in wrong format for WebTrends Reporting Services:

'==========================================================================================
'= Program:  WebTrends Logfile Fixer for IIS
'= FileName: ConvertLogFiles.vbs
'= Description: This script searches a directory for ex*.log files and converts them to
'=              ex*c.log files.  This conversion process simply inserts a date field if
'=              none is present.  This script was written to address compatibility issues
'=              with our IIS logfiles and WebTrends.
'=                  This script recurses through all subdirectories, so make sure that you
'=              Have adequate disk space for all related logfiles.
