[Exchange 2010]ASP foutmelding bij openen OWA.

[FreakNL]

Een leuke dit, waar ik al een paar dagen mee aan het stoeien ben;

Case;
Exchange server gecrashed vanwege crash op virtuele host. Databases waren kaduuk, en services wilden niet meer... Meeste is al opgelost, en bijvoorbeeld Outlook clients kunnen "gewoon" weer connecten.

Ik blijf echter problemen houden met mijn OWA omgeving;

1) Als ik de OWA pagina open, krijg ik netjes een inlogscherm
2) Als ik dan inlog worden mijn gegevens ook netjes gechecked (bij verkeerd wachtwoord komt login form terug).
3) Bij correcte inlog krijg ik de volgende error voor mijn neus;

code:

Server Error in '/owa' Application.
Could not load file or assembly 'Microsoft.Exchange.Clients.Owa' or one of its dependencies. Strong name signature could not be verified.  The assembly may have been tampered with, or it was delay signed but not fully signed with the correct private key. (Exception from HRESULT: 0x80131045)
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.

Assembly Load Trace: The following information can be helpful to determine why the assembly 'Microsoft.Exchange.Clients.Owa' could not be loaded.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Custom event details:

Wat ik al geprobeert heb;

1) C:\Program Files\Microsoft.NET\SDK\v2.0 64bit>%SYSTEMROOT%\Microsoft.NET\Framewo
rk64\v2.0.50727\aspnet_regiis.exe -i
(om asp.net opnieuw te registreren
2) CAS rol uninstallen en opnieuw installen
3) Met sn.exe aan het prutsen geweest om Strong Name Validation uit te schakelen. Ik kom daar echter niet verder mee, en denk ook niet dat ik daarmee op de goede weg ben.


Is er iemand hier die een tip voor mij heeft? Ik loopt een beetje vast... Er is ook bar weinig op Google over te vinden. Wel over strong name dinges in zijn algemeenheid, maar niet met betrekking tot Microsoft.Exchange.Clients.OWA ...

[FreakNL]

Nou, dat was uiteindelijk vrij simpel. Ter latere referentie;


Microsoft.Exchange.Clients.Owa.dll gekopierd vanaf de Exchange 2010 CD en in de originele map (D:\ExchSRV\ClientAccess\Owa\ Bin\) de andere overschreven.

Hij was waarschijnlijk corrupt geworden tijdens de crash.
