oma not working

[cstarkey6]

Hi- Win2K3 w/ Exchange 2K3 - try to open OMA and get a blank page with event log showing the following 1503 error.

An unknown error occurred while processing the current request:
Message: Type 'OmaAdapters.OmaXhtmlMultiLineTextBoxAdapter,Micro soft.Exchange.OMA.UserInterface' used as adapter not found. (D:\Program Files\Exchsrvr\OMA\Browse\web.config line 102)

Any ideas?

Silly question but did you enable OMA in the first place? Did it ever work? One server? Front-End?

We need info.

Sorry, more info - never did work. OMA is enabled. RPC over HTTPS works fine. This is a single exchange box setup - RPC-HTTP back-end server. Also, followed your instructions for creating a secure OMA virtual directory. The server has it's own ssl cert which works fine.

Using Internet Explorer on your desktop (not on the server or handheld), turn off Show Friendly HTTP error messages in the options.
Then browse to OMA. It should throw an error in the browser window. What does that error say?

As you are using SSL, make sure that you do NOT have require SSL enabled on either /exchange, /oma or /microsoft-server-activesync virtual directories. That doesn't stop you from using SSL, just stops you from forcing the SSL connection.

IE gives me just a blank page - no errors and a URL string that reads: https://nts1.*********.com/oma/(nren...peqg)/oma.aspx.

Fixed this! I ran the .net 1.1 update again (per another post on this site) and it resolved the problem. Thanks.
