IIS 64bit / IIS 32 bit == Differences between running .net applications?

We have a web based application that runs in IIS6.0 on windows 2000/2003. A
client wants to know if it would be possible for us to load our application
on a Windows 2003 64 bit server. Would our application still work? Are
these knows incompatabilities between the two?

Thanks!

 

I mean, it says this on MSDN:

"Windows Server 2003 x64 provides high performance for both 32-bit and
64-bit applications on the same system. The underlying architecture is based
on 64-bit extensions to the industry-standard x86 instruction set, allowing
today's 32-bit applications to run natively on x64 processors. At the same
time, new 64-bit applications are executed in 64-bit mode, which processes
more data per clock cycle, allows greater access to memory, and speeds
numeric calculations. The end result is a platform that leverages the
existing wealth of 32-bit applications while also providing a smooth
migration path to 64-bit computing. "

" for both 32-bit and 64-bit applications on the same system"... so, both
should work, right?

 

Yes, both work, except to use the 64-bit side and your application uses
..NET, it must be version 2.0, as it is the only one with a x86 and x64 bit
version, otherwise if it uses 1.1 or 1.0, you'll still be in x86 mode on
IIS. That said though, the underlying workings of the OS/IIS is still x64,
which can utilize more memory and is more robust. You'll also have to set
IIS to run for x86 applications and have at least 2 websites, one in x86
mode and one in x64 mode, that is if your app supports x64 bit.

 

Hi !

Yes and no ;-)

If you need client posting capabilities, you'll usually need something
like "FrontPage Server Extensions" and/or "Windows Sharepoint Services".

I do not know, if "FrontPage Server Extensions" are available for "x64
standard". On "x64 R2 standard" only Sharepoint services are available
and they are 32 bit !!!!!!!!! If you install it, they configure you IIS
to only use 32 bit mode and your 64bit abilities are lost. They also
install a 32 bit SQL Server Express DB. This also seem to setup a 32bit
provider for VSS, which prevents backup completely from running. I
solved this problem by removing "Sharepoit Services" and everything is
fine, except, that VS canot post solutions!!

If you are using "Windows Server 2003 x64 Standard Edition" I would
please you to look for the availability of "Frontpage Server Extensions"
in your setup(Controlpanel, Software, System components). I would like
to know that! I was on the road to install this, just to find this out ;-)

Thanks so far and
best regards,
Manfred

 

I don't have personnally a 64 bit server but it looks like that many ODBC
and OLEDB drivers won't work in 64 bits mode; as I had to put the IIS on 32
bit mode for one of my client (the only one with a 64 bit machine) to make
my stuff work.

 

I have not looked into this for a while, but the last time I did, Front
Page Server extensions will only work in 32 bit.

In order for them to work properly, you must step IIS down to 32 bit
mode by running a script...or command line...I don't have it handy, but
will try to find the KB article and post it.

Hi !

Anyway, thanks. Hmm, I am wondering, why I did'nt make a search on MS's
"extended search query" .....

It just now gave me the link to the download of the "FrontPage Server
Extensions 2002 for Windows x64":

http://www.microsoft.com/downloads/...F9-3C78-44BB-8A72-6F8ED2AA0E8E&displaylang=en

Hi !

After reading: http://support.microsoft.com/kb/891314/en-us
I am completely disappointed, due to:

To run FrontPage 2002 Server Extensions for Windows x64 editions,
Microsoft Internet Information Services (IIS) must be configured to run
in 32-bit emulation mode.

What a mess!

Best regards,
Manfred

 

I wish Microsoft would have made the extensions compatable with true
64bit, but sadly they have not yet. A 64 bit server running IIS in 32
bit mode should still handle memory better correct?

Does anyone know of any problems on production servers using the front
page extensions?
