    Exchange 2007 OWA problem

    Hi all,

    My Exchange OWA is stuffed after installing some windows updates last night. The server is acting as a OWA server only with the mailbox role being on another server. Event log is showing this error over and over again.

    Code:
    Event code: 3008 
    Event message: A configuration error has occurred. 
    Event time: 02/07/2010 12:10:30

    Custom event details:
    I have googled but nothing is showing up about the error line "Could not load file or assembly 'Microsoft.Exchange.Clients.Strings" The only articles i can see are to do with Sharepoint being installed but we dont have sharepoint.

    Any one got any ideas?

    I have even removed the Client Access Role and re-installed it with no success.

    Cheers

    From the log I've picked up an Is Authenticated: False. Looking at the previous lines this gives an invalid argument with a number
    0x80070057

    Put that into a Technet search and there are a number of items listed. Not been through them all but they might be useful. Also have you looked at your Certificates, are they valid?
    Just some thoughts hope they help.
