Hi,the fail of the installation of an update, made all services of exchange startup typeto be set as "Disabled"..Could anybody provide me a list of default exchange services startup type? Automatic-Manual-Automatic (Delayed) etc..Really thanx a lot!

Check this out to find which all are required services based on the Exchange server roles which you installed on your server. Services Installed by Exchange Setup http://technet.microsoft.com/en-us/library/aa998342.aspx Amit Tank | MVP Exchange Server | MCITP: EMA | MCSA: M | http://ExchangeShare.WordPress.com

it's useful but it doesn't tell me the startup type of services..

Did you attempt the installation only once and failed? Or it failed and attempted installation more times also... If you attempted only once, failed and you have all services disabled, never attempted more time then runServiceControl.ps1 -AfterPatch in Exchange Script installation folder which will set all services to their default state which they were before you tried to install update...

Too bad you didn't get an answer to your question, since this is the first page google turned up when I asked the same question. Some $245 Microsoft Exchange monkey changed all my Exchange services startup types, then didn't put them back after he decided he couldn't solve the problem. In my experience, you have about 1 chance in 10 of getting a decent answer to a question when selecting social.technet.microsoft.com from the search results. The rest of the time somebody answers your question with another question (often, like "why do you want to do THAT"), imparts information that does not answer your question, or sends you off to a link that is a waste of time. If I do find the answer, I'll come back an post it for the next person who gets sucked into thinking there's a real answer here.

I don't see one documented for 2007, however... When Exchange 2007 in installed with HUB, CAS and Mailbox server roles. Services and their default start up modes are listed in the following table. Service Name Default Startup Mode Microsoft Exchange Active Directory Topology Automatic Microsoft Exchange Anti-Spam Update Automatic Microsoft Exchange EdgeSync Automatic Microsoft Exchange File Distribution Automatic Microsoft Exchange IMAP4 Manual Microsoft Exchange POP3 Manual Microsoft Exchange Mail Submission Service Automatic Microsoft Exchange Mailbox Assistants Automatic Microsoft Exchange Information Store Automatic Microsoft Exchange Replication Service Automatic Microsoft Exchange Search Indexer Automatic Microsoft Exchange Service Host Automatic Microsoft Exchange System Attendant Automatic Microsoft Exchange Transport Automatic Microsoft Exchange Transport Log Search Automatic Microsoft Search Exchange Manual Microsoft Search Monitoring Manual James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com
