Question: Did you try this out on WinNT4.0 SP4,SP5,SP6 running IIS 5.0? Fact about dataloss: I think even if it restarts automaticly the bug MUST be fixed. On large servers with couple of hundred clients doing downloads a restart would still mean abort of data transfer. 2 processes watching each other is not new to me, but the main point is still a stable server, another process for watching is extremely usefull but no way out. Microsoft should prepare a fix for IIS5.0 . I would be glad Microsoft to make a statement about the past 2 bugs and prepare fixes (or service packs as they call ;-} ) for "ida" and "idq" extension and built on that basic my Access Violation produced with help of the URL structure "domain./.......//......ida". Danger: The fact at this point is that it is possible to crash IIS 5.0 and the process must be restarted what means data loss at all clients connected. On a CreditCard transaction / Stock Systems it would mean dramatic financial loss. The main danger is not, that a website with few hundred visitors will become unavailable for some seconds, but if it is a SSL System which handles transactions get's interrupted while datatransfer. Imagine you sell shares for 200.000$ and your order get's interrupted you may loose a _lot_ of money. Most transactionsystems are Unix but in the past more and more NT Systems have been used for this kind of business. greets Lark Lizerman > > > <SNIP> > >I have 2 screenshots where 2 of the messages are displayed. > >The system I have tried it out is a cluster where each backups the other on > case of failure. > >Because of that reason I can not guaranteed say if the process dies or not, > because I got redirected to another server. > > <SNIP> > > IIS5 on Windows 2000 has a resilience system built in where if the > inetinfo.exe process crashes it will automatically restart - the program > that does this is %systemroot%\system32\iisreset.exe with a /fail=failreason > option.
