I wastrying to configure exchange 2007 OWAwhen Icame across some issues withOWAvirtual directories. I tried to recreate the OWA virtual directories but the problem persists. Anyway I found and tried to implement the following KB: http://support.microsoft.com/default.aspx?kbid=320202 Unfortunately, after I removed the "client access" server role, the exchange refused to reinstall it. The following error occurred every time I try: ---------------------------------------------------------------- Summary: 2 item(s). 0 succeeded, 1 failed. Elapsed time: 00:00:41 Copy Exchange FilesFailed Error:Installing product D:\exchangeserver.msi failed. Fatal error during installation. Error code is 1603.

Fatal error during installation Elapsed Time: 00:00:41 Client Access RoleCancelled --------------------------------------------------------------- Any Ideas??

Hi Zuhair, First thing try to download fresh copy of Exchange 2007 SP1 from Microsoft website and try to install. http://www.microsoft.com/downloads/details.aspx?FamilyId=44C66AD6-F185-4A1D-A9AB-473C1188954C If fresh source of Exchange 2007 SP1 gives same error then check for the setup log file for further detail. Exchange 2007 setup logs and how to use them to troubleshoot setup http://msexchangeteam.com/archive/2007/05/07/438433.aspx

Is this server performing other Exchange roles or anything else? If not, I'd just use a fresh build of Windows. Outside of that, you'll probably have to get your hands dirty with IIS. When I first read your post I thought I could be more helpful! Joseph Durnal

Thanks for your help.. I tried to install a fresh downloaded Exchange SP1 and the same problem occurred. Also after checking the setup logs I found the following errors logged: MSI (s) (40:E0) [09:56:29:282]: Product: Microsoft Exchange Server -- The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2920. The arguments are: Microsoft.Exchange.Services.web.config, , DEBUG: Error 2920: Source directory not specified for file Microsoft.Exchange.Services.web.config. MSI (s) (40:E0) [09:56:29:282]: Product: Microsoft Exchange Server -- The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2920. The arguments are: Microsoft.Exchange.Services.web.config, , It seems that some files are missing from the Service Pack!! Waiting for your reply..

Hi Zuhair Is this a brand new installation? Is the Exchange 07 setup is on the same server as the AD or a separate server (Exchange only)? The best thing to do is if it is a new server then download the Fresh Setup and do the Brand New instllation. I never faced any problem during the Exchange 07 installation. regards Adnan

It is in a separate server than the AD. I need to reinstall the "Client Access Server Role" and get OWA working. Other roles are working just fine. any one guys??

Hi, i have same problemAnybody help us?

Have you tried installing from the command-line using setup.com? Also, are the source files copied locally to the server? Finally, the only other thing I can think of is whether IIS has been uninstalled/reinstalled before re-attempting the CAS install? I'm not sure you'd have to do this, but it's worth considering.

Hey , It may be difficult to install CAS role without the IIS virtual directories.Setup always fails. here are some suggestions 1) First remove all previosu entries for Exchange 2007 virtual directories. Remove-OwaVirtualDirectory "exchange (default web site)" Remove-OwaVirtualDirectory "public (default web site)" Remove-OwaVirtualDirectory "exchweb (default web site)" Remove-OwaVirtualDirectory "owa (default web site)" 2) If it is not getting removed using these commands. download the metabase explorer tool(IIS resource kit) and delete the above mentioned virtual directories from Metabase. 3) Reregister the ASP.NET version for exchange 2007 sp1 To run the 64-bit version of ASP.NET 2.0, follow these steps: Click Start, click Run, type cmd, and then click OK. Type the following command to disable the 32-bit mode: cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 0 Type the following command to install the version of ASP.NET 2.0 and to install the script maps at the IIS root and under: %SYSTEMROOT%\Microsoft.NET\Framework64\v2.0.50727\aspnet_regiis.exe -i Make sure that the status of ASP.NET version 2.0.50727 is set to Allowed in the Web service extension list in Internet Information Services Manager. Note The build version of ASP.NET 2.0 may differ depending on what the currently released build version is. These steps are for build version 2.0.50727. http://support.microsoft.com/kb/894435 4) Recreate the IIS virtual directories .Here are the commands To re-create the Outlook Web Access-related virtual directories, type the following commands at the Exchange Management Shell. Press ENTER after you type each command: New-OwaVirtualDirectory "exchange" -OwaVersion Exchange2003or2000 -VirtualDirectoryType Mailboxes -WebSiteName "Default Web Site" New-OwaVirtualDirectory "public" -OwaVersion Exchange2003or2000 -VirtualDirectoryType PublicFolders -WebSiteName "Default Web Site" New-OwaVirtualDirectory "exchweb" -OwaVersion Exchange2003or2000 -VirtualDirectoryType Exchweb -WebSiteName "Default Web Site" New-OwaVirtualDirectory -name "owa" -OwaVersion Exchange2007 -WebSiteName "Default Web Site" Once you have new virtual directories you can complete the CAS installation. Let me know IF you have any Queries.

Dont work1. I Have IIS installed2. I have 64 bit ASP.NET enabled and installed3. in IIS i can only create exchange and public directory. 4. New-OwaVirtualDirectory "exchweb" -OwaVersion Exchange2003or2000 -VirtualDirectoryType Exchweb -WebSiteName "Default Web Site"write this :New-OwaVirtualDirectory : 'MAIL' does not have the right Exchange Server version or role required to support this operation.At line:1 char:24+ New-OwaVirtualDirectory <<<< "exchweb" -OwaVersion Exchange2003or2000 -VirtualDirectoryType Exchweb -WebSiteName "Default Web Site"and when i try to install CAS Role i have now this error:Summary: 2 item(s). 0 succeeded, 1 failed.
