We just recently got a second server and we have it watching the first server to see if it's crashed or not
How we do that is the first server calls a taf on the second server every minute and that taf inserts a timestamp in a table. IIS crashed on the first server so that it wasnt serving pages but witango was still operating so the second server was receiving the taf calls every minute so everything still looked ok even though it wasnt which confused me a little. I was just kind of confused as to what was going on but have it cleared up now hehe. ----- Original Message ----- From: "Scott Cadillac" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, June 25, 2004 11:48 AM Subject: RE: Witango-Talk: crontab file > Good question Alan, > > I doubt the webserver is involved.
