G'day guys,

DCOM was unable to communicate with the computer COMPUTER.domain.local using any of the configured protocols

Having all issues resulting from a migration from SBS 2003 to SBS 2011. The problem is that it was working fine, a couple days ago, last night I updated to SP1 and today some users are complaining of not being able to access VPN's or emails aren't coming through or what not.

Something big must have stopped working.

I don't know where to start, I found that DCOM in event viewer is spitting out errors like this all the time.

Help would be muchly appreciated.

Steve

I have errors on VPN connections stating that no logon servers are available ...

Something big is broken,

I have run the best practices on Exchange and that comes back fine, few minor issues...
I have run the network connectivity fix and that is fine
Services are all started and working...

Stressing :(

Which DCOM error are you referring to, is it Event ID 10009 or 10016. Please be more specific. However I would suggests you to check this link which is applicable to SBS 2011 as well.

Sorry for the delay guys,

Error is 10009

I'm not well versed in Windows, so tell me what you need and I will find it.

Cheers,

Steve
