Exchange 2007 OWA problem

[mcloum]

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.

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.

All seems to be working now after removing last nights updates and re-installing them. cheers
