The cache not updating on my Windows 2008 R2 servers is still a persistent =

I believe the problem may be related to IIS. Some background on what I've=20
been experiencing this week.
I have three servers running IIS 7.5 with the openafs 1.7.4 client. I have =
one website that is only served from one of these servers at a time. What=20
I've seen in the last few days is the web developers will inform me that=20
changes they have made to the website are not showing up. I checked the=20
active server and the content is indeed not showing up but it is available =
on the two stand by servers. I flush the cache on the active server and=20
everything is updated. The web developers then make more changes a few=20
minutes later and now the changes will not show up on any of the three=20
servers. Since I had just checked the two stand by servers this started up =
the application pools in IIS for the website on all three servers which is =
what leads me to believe this may be IIS related.
Could anyone provide me with ideas on troubleshooting and isolating this=20
problem?

RE: [OpenAFS] Strange AFS update behavior.
The problem resurfaced again on my servers running 1.7.4 today. These are=20
IIS 7.5 servers and the file in question was an aspx file.
Navigating to the the directory in powershell I see the file has the=20
correct time stamp. Opening the file in notepad I see the old file.
Performing fs flushv on the directory allows me to open the correct file=20
in notepad but IIS continues to serve the old file as if it hasn't=20
received notification of the file change.

Did upgrading to 1.7.4 fix this issue?
I have had reports on similar issues on our Windows 7 lab computers (with=20
1.7.1 and maybe 1.7.2). After upgrading to 1.7.3 I have not heard of this=20
but that might not mean that the issue is gone. I have never been able to=20
replicate it myself though. This and the next week we will upgrade to=20
1.7.4 and hope that it will perform even better.
