Great concept, poor execution guys.

Ok, I have seen the demo killl a box 6 times now. After seeing all the other software removed and just isapi r/w, I found it stopped responding to any type of traffic, including no ping, no termservcs, nada, zip, zilch, dead... This has occured on a fresh installation twice within 15 days of using the demo. Yes, a couple of times after uninstalling it, it took out other windows components thus killing the box, again... I no longer have the patience to reinstall windows at the USC datafacility for a 7th time.

I am not gonna mention that at first it works fine, a day goes by and the jpgs I had protected and swapped with spacer.gif. Oddly enough surfing my own site, I was seeing my logo vanish and get replaced by the spacer.gif.

Now, yeah, I can clear my cache, but what about my users that are not web savvy? The log files reveal nothing.

You guys have a lot of work cut out for you before this is anything remotely stable.

Must say I haven't seen anything like this using W2003 Server serving over 10 million pages a month with the software.

You'd better to check your system and application first before complaining on ISAPI_Rewrite.

It is very easy to say 'user error' but I am talking fresh installs. 10 million pageviews is hardly anything to even flinch at. I serve gigs of images perday and the no hotlink feature is what I wanted. I suspected a memory leak, and I even went as far as fresh installs of 2k. It seems that on a few occasions, the uninstall of the demo has been the achilles heel, so in one case I installed the demo and never uninstalled it and it was fine until I had to wipe and retask the box. Earlier versions form circa 2003 were fine, more recent versions have eaten it.

Perhaps it has to do with the speed at which the images are requested as hotlinks to my images numbered over 10k (per day) at a peak last year, and httrack has been sent after my site so many times along with spoofed referrers.

I run and admin 20 servers located at USC and have been running 2k since the day it was delivered I my cages, sh*t happens, but not that often to me, nor as clearly inconflict with certain apps. I think that in one instance SecureIIS and the app were at odds, another time iMail. And certainly Helm hates the app.

All I am to do is save my own personal bandwidth transfer issues.

And it is very easy to say "ISAPI_Rewrite error". As I have already told, you could expirience problems with OS itself and fresh install will not help here. 
 
>I serve gigs of images perday and the no hotlink feature is what I wanted.
 
So, your server handles more than 1000000000 requests per day? Sorry, but it look improbable. It is more than 11000 requests per second. I have never seen software server capable to process such number of requests per second. If you are talking about traffic then traffic is not a measure here. Only number of requests is important.
 
>It seems that on a few occasions, the uninstall of the demo has been the achilles heel, so in one case I installed the demo and never uninstalled it and it was fine until I had to wipe and retask the box.
 
That also seems improbable. Installation/deinstallation of ISAPI_Rewrite is a very simple procedure. It does not affect any system components except a few records in the IIS metabase.
 
>Earlier versions form circa 2003 were fine, more recent versions have eaten it.
 
I do not understand what do you mean here. What is "earlier version form circa 2003"? And what has been eaten by more recent versions?
 
Sorry but I could not provide any constructive response with such "information". If you really want to troubleshoot the problem (and not just to complain about our product) please be more specific. Describe your hadware, OS version (including SPs), ISAPI_Rewrite version number, configuration files and exact problem symptoms.

In most cases all the services stop and will not restart, and once you have that, I uninstall Ir/w and whammo, no response from the box, it takes out some windows component.

Ok, I have images that are up tp 2 megs in size, and I have video, as well being served. It is very easy to serve gigs per day, as a site I helped build in 2000: www.vipmodel.com can attest. For more than a year, in the search engines I was the first listing for ferrari videos as an active member of the club, also top ten in models, playboy casting, many many trade specific related terms and names of celebrities as well.

The servers coming into my racks have had fresh drives shipped from IBM, Dell and personal installs. Hard to think that we all have bad installs. I am trying to help you perfect your product, not thrash on it.

I am sure I am not the only person getting the error, but perhaps the only one posting to the forum.

Isapi Rewrite known conflicts: Helm, SecureIIS, iMail, Xcompress. Everytime Isapir/w and any of these apps are on the box (default, no customizations) they conflict. They do not conflict with one another, and not immediately with Isapir/w, but after a load test by running them live for about one-two weeks. The only known immediate death without making it go live is having any of these apps, and trying to uninstall isapi rewrite.

Well, that is the first reason why I do not believe that it is the ISAPI_Rewrite's problem. ISAPI_Rewrite could not affect anything except IIS. If you are expiriencing problems with other services then the problem is almost surely inside the system components.
 
>Ok, I have images that are up tp 2 megs in size, and I have video, as well being served.
 
As I have already told object size means almost nothing here. Only number of requests is important. ISAPI_Rewrite takes part only in a very small part of request processing. And data transfer is beyond its scope.
 
>The servers coming into my racks have had fresh drives shipped from IBM, Dell and personal installs. Hard to think that we all have bad installs.
 
No, I am trying to say that this could be an OS problem (MS bug or "feature"). Have you tried to search MS KBs or conferences?
 
>Isapi Rewrite known conflicts: Helm, SecureIIS, iMail, Xcompress.
 
Sorry, but I have never seen these apps, so I even could not imagine how they could conflict with ISAPI_Rewrite.
 
>The only known immediate death without making it go live is having any of these apps, and trying to uninstall isapi rewrite.
 
Are you trying to say that if you have one of those apps running along with ISAPI_Rewrite and trying to uninstall ISAPI_Rewrite you will get a dead system? ISAPI_Rewrite installation itself could not produce such effect.
