Installation lansweeper on Exchange Server 2007 - Exchange IIS now don't work

[Christian]

Hi,

I have made a big mistake, I have installed the lansweeper on an exchange 2007 server (sp1) and now (after the deinstallation, too) the OWA doesn't work.......I think It could be a problem with the .net framework....lanswepper installed an older version or 32bit version, does it!?

What can I do?

What do the lansweeper installer "really" .What do it in background.....

....SQL Express 2005
.... .NET 32BIT????
...add virtual Directory to the ISS (ISS 7.0 support - does ist crash my ISS after install/deinstall)
....many files
.....an the lansweeper service....

what else?

Thank you for your support

Did you install Lansweeper website in the default website or as a virtual directory?

I have found the answer by my self.

By the installtion the lansweeper installer installed an 32Bit Version of the .NET 3.5
Then it change the runlevel fom 64bit ti 32bit or through the .net installation.

A Exchange 2007 Server with 64Bit is then diabled or the iss is the not usable.

But how I fix it......magic -->

Change IIS to run in 64bit mode <http://blogs.sharepointace.com/post/Change-IIS-to-run-in-64bit-mode.aspx>

If you are running a 64bit OS, IIS by default will be running in 32bit mode. This will be a problem once you start going through the install process for MOSS 2007.

The command you want to run to change the mode on IIS is:

cscript DriveLetter:\inetpub\AdminScripts\adsutil.vbs set w3svc/AppPools/Enable32BitAppOnWin64 0

If you have previously installed .NET 2.0 framework and it is enabled in IIS, you need to uninstall it first. The command to do this is:
Framework\v2.0.50727\aspnet_regiis -u

Then, install and enable the .NET framework for 64bit using this command:
Framework64\v2.0.50727\aspnet_regiis –i

Once you do this, you should not get the message that ASP 2.0 is required and should be set to “Allow” on IIS Web Service Extensions.

Christian's link to the proposed solution resolved my problem. I have SharePoint (WSS 3.0) running on a Windows 2008 64bit server. I slapped LanSweeper on it and it LanSwept my working SharePoint site away. After following the instructions posted earlier (quoted below) I now have WSS 3.0 back and LanSweeper workking like a champ.
I use LanSweeper in a 32 bit environment for another company and LLOOVVEE it. I always feel like I'm griping when I suggest something. So please LanSweeper gurus don't take it that way. But, with the growing commonality of SharePoint (or OWA) in 64bit environments perhaps you could have a separate 64bit package that takes care of these little issues during the install process or a package that detected 32 or 64 bit IIS.

We are aware of the problem, new installer is on it's way, only windows7 64bit support is not yet ready.
