Question
Outlook Web Access (OWA) shows Unspecified Error on Small Business Server 2003, Event ID 2050 in Event Log
I have a client with SBS2003. We have Exchange installed with OWA on the same server.
When they browse to the default site that has the Exchange Virtual Directory for OWA, they are prompted for username/password.
When we enter in the correct credentials, it acts as if the mailbox is
loading, however, we get an error, "Unspecified Error" when friendly http
errors are turned off.
We are also getting event ID 2050 in the application log of the server. The
description is as follows:
MSExchangeDSAccess ID:2050 The shared memory heap could not be created.
We also get this each time:
DAVEX ID: 101 Davex to be shutdown. Version 6.5.6944.4
Any Help would be greatly appreciated.
Thanks,

I ended up rebuilding the Exchange Virtual Directories that are needed for OWA and reset the permissions per this MS KB article:
http://support.microsoft.c
Then after that I checked event viewer and noticed that I had numerous FRS errors within Event Viewer also. So I went ahead and rebuild the FRS Jet database by doing the following:
1. Open a CMD prompt on the domain controller and stop the NetLogon and Ntfrs services:
net stop NetLogon
net stop Ntfrs
2. Type:
del %systemroot%\ntfrs\jet\Ntf
del %systemroot%\ntfrs\jet\Sys
del %systemroot%\ntfrs\jet\log
del %systemroot%\ntfrs\jet\log
del %systemroot%\ntfrs\jet\log
3. Type:
net start NetLogon
net start Ntfrs
4. Check the FRS event log for expected warning 13514 and 13520.
5. In five minutes, recheck the FRS event log for informational messages 13553, 13554, and 13516.
After I did this, I went back into IIS manager, reset the Default Website Vir Dir permissions to allow anonymous access only and tested OWA... it worked perfectly.
Thanks for the response though.
Yikes... that's a nasty KB article... too complicated for my taste....
If you follow this one, http://support.microsoft.c
Just follow that with running the Configure Email and Internet Connection Wizard (CEICW -- which is linked as Connect to the Internet in the Server Management Console > Internet and Email)
A visual how-to is here: http://sbsurl.com/ceicw and a full networking overview for SBS is at http://sbsurl.com/msicw
Within that wizard you'll see a "more information" button on each screen that has invaluable help in deciding which options to select.
Be sure to check those out as well.

HI, you may need to reinstall some things. But first can you try to put in DOMAIN\Usersname format on the username field and see if that makes a difference.
By the way in future support requests should go to the SBS topic area.
