Default Web Services Stopping For No Apparent Reason 1

[votequimby]

I'm running IIS on an NT 4.0 server, and Default Web Services keep stopping without warning some 10 times per day.&nbsp;&nbsp;There is no degradation of performance prior to the event, and there is no trace of a problem in the Event Log.&nbsp;&nbsp;Simply re-starting Default Web Services solves the problem until the next time.&nbsp;&nbsp;Has anyone encountered this before?<br><br>Thanks!

Not seen this but if your MDAC and SP's are in conflict this could certainly produce a similar result

The problem turned out to be caused by a defective version of aspchart.dll .&nbsp;&nbsp;The technical details are Microsoft's secret, but whenever a user would request a page that called aspchart.dll, Default Web Site would stop.&nbsp;&nbsp;This explains why there were no warning signs in the NT Event Log or Performance Monitor.&nbsp;&nbsp;As soon as we replaced the dll and updated the registry accordingly, the outages stopped happening.
