To Index or Not To Index or How To Index Hello, I was wondering if someone knows a better way to explain how different indexes work. Such as, is it better to have an index with int type or char or varchar etc? Is it better to have composite indexes or indexes with individual columns? How does optimizer handle different indexes and what can we do help it? Indexes are very efficient most of the time but they can be quite detrimental to server's performance, if abused. Perhaps you know of a good article about indexing that you could share with us. Or, perhaps Mr. Rob Verschoor would like to issue an article in his very usefu...

When I let the prog search for index.dat, it also comes up with a file whose name contains index.dat, in my case C:Team17WORMSB~1Datagmindex.dat I do not want that one to be included, so I deselect the file from the results list. However, the generated batch file still contains a del for this (and as I have noticed, other) excluded file(s). Hm. Anyone noticed this too? I have Windows XP Home SP2.

The explanation says that ZA has blocked access to Port 53 on a DNS server. Why would ZA block this? As far as I know, it has never requested permission to access this server and I have never denied such permission. I use a Netgear router, and in order to make it work with my system, I was instructed to configure the DNS Configuration of the TCP/IP Properties of my network card and add 4.2.2.2 as one of my DNS Servers.
