Question : ActiveSync Mobile Not Working on SBS 2003 Virtualized in ESX 4.0

We had been using Activesync mobile on our SBS 2003 Exchange Server (SP2) successfully.  We then virtualized onto VMWare ESX 4.0 (P2V) successfully.  Everything worked except immediately all PDAs no longer could Activesync Mobile.  Deleted and re-created all Exchange VDirs. Set registry MAS Parameters to Exchange-OMA (tried both with and without "/" in front of entry).  Verified all ApplicationPools.  Still cannot browse OMA VDir (either internally within IIS Manager or externally), but can successfully browse exchange-oma VD, Exchange VD, or any other.  Receiving Application Log errors 1503, 3030 (even though I've already disabled Forms Authentication in HTTP Protocol within Exchange Manager.  Error when browsing OMA is:

Server Error in '/OMA' Application.

Collection was modified; enumeration operation may not execute.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidOperationException: Collection was modified; enumeration operation may not execute.

Source Error:

The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:

1. Add a "Debug=true" directive at the top of the file that generated the error. Example:

  <%@ Page Language="C#" Debug="true" %>

or:

2) Add the following section to the configuration file of your application:

<configuration>
   <system.web>
       <compilation debug="true"/>
   </system.web>
</configuration>

Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.

Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.
