Outlook Web App didn't initialize
Hi guys, I've this problem when accessing OWA Exchange 2010, I've got 2 node CAS and doing a NLB for both of them. Then suddenly this error happen : OWA Web App didn't initialize, and the weird things are it happen both of the nodes. -.-" I've already check the configuration, web.config, it's already correct. Then I went into event viewer I found a clue there's something wrong with the /owa virtual directory authentication : Event ID 30 So I reset the authentication according to this link : http://technet.microsoft.com/en-us/library/bb218557(EXCHG.80).aspx node1 and node2 show the event ID 30 at different time , several hours different, my question is How can it be the OWA authentication changed but no one changes it ? Is it a bug ? I need to know that it will not going to happen again. node1 : Exchange 2010 RU4, Windows 2008 SP2 node2 : Exchange 2010 RU4, Windows 2008 R2

Per my research, there’s no bug that shared the same symptom Please check the other events before the event 30, see if there’s related ones with IIS configuration You can enable IIS Configuration Auditing on the windows server, and then monitor the changes on the IIS Resources: IIS 7.5 – How to enable IIS Configuration Auditing?Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
