Exchange 2003 reinstall over damaged installation

I am running Exchange 2003 on a Windows 2003 Server box.  Last week one of my co-workers deleted the Default Web Site in IIS. We are trying to get the Microsoft Direct Push and OWA, Exchange ActiveSync, etc working.  I have read that this is impossible with out this Default Web Site that Exchange creates when installed? Is this correct? I need to get that site back now.

I have followed the steps in this article: http://support.microsoft.com/kb/883380 to no avail. I heard from someone else say that I could just reinstall Exchange over the top of my current install (sort of repairing) the installation. This is outlined in this article: http://technet.microsoft.com/en-us/library/497127b0-7283-4c69-9a34-27185978bb07.aspx 

My question is, if I follow the procedure in the article above, will it delete my stores? I am confident that I have a backup just in case it destroys it, but will it delete, corrupt, overwrite my current stores?  I am scheduled to do this today so please get back to me soon. Thanks for the help.

I am not convinced that reinstalling would recreate the default web site, although it might.  Reinstalling Exchange doesn't delete the stores, but you may find that you need to reinstall IIS to get the DWS back.  If you do, then Exchange must always be reinstalled after IIS.

It may be easier to recreate the Default Web Site.  The Default Web Site is just like any other, but it has an ID of 1, instead of a random number.  I would suggest creating a new Web site in IIS Manager, name it 'Default Web Site', then click on the Web Sites container, and note the ID in the left hand pane - it will be something like 8000xxxx .  Then look at the properties of the server, and enable Direct Metabase Edit.  Then find you Metabase.xml file in C:\Windows\System32\Inetsrv and make a copy of it (important). Open it in Notepad, and do a search and replace.  Replace the 8000xxxx number with 1 .  Save it back, and restart the WWW service.

I've never tried this, I hasten to add, but I think it would work.


So I should be able to reinstall IIS and then Exchange and my web site should return. Do I need to dismount the stores before reinstalling?

a resinstall of exchange will stop and restart the exchange services. this will also dismount the stores


The IIS and Exchange re-install worked great. Thanks
