It is highly recommended that you restart all Exchange services to correct this issue.

Can you let us know what SQL and Exchange are doing on the same server?Is this default installation of IIS or some changes has been done on it? Have you updated your Anti virus recently. Can you disable the AV for a while and then try to restart the IIS services?Raj

Thank you for your repose Raj, Yes, default installation of IIS 6.0, AV Trent micro is updated on today only, I will check with my server without AV services.

Hi, Even we have disabled the AV services also, but still we are getting the same error.

Hi,As my understanding,after you have apply kb 895407, IIS Admin service cannot start,is that ture?Then I'd like to know what areother application thathas been installed on the Exchange Server?Please check event log and post the detail error event which is related to IIS service.Also please check task manager to see if memory has been in high usage.Regards,Xiu
