# This computer is unable to establish a trust relationship with the server.

• ### Question

• More SBS2003 to SBS2011E migration issues.

This is a windows XP machine with all available patches installed. It's been part of the domain since before the migration. My new server is named "Alpha" and I've successfully run the command "net time \\alpha /set /yes" to make sure that my time is synchronized with alpha.

"Cannot connect this computer to the network. This computer is unable to establish a trust relationship with the server. Verify that the computer’s date and time are accurate and try again."

The log declares:

I've not been able to figure out what the invalidcert issue is, or more importantly what I need to do to fix it.

• I found this thread, which mentioned this article and was able to get the machine to join the dashboard properly. I added the local machine administrators group to the security permissions with full access on the C:\Documents and Settings\All Users\Application Data\Microsoft directory. "Everyone" already had access to that directory, but the change seemed to fix things along with the fact that I was logged in with a LOCAL machine administrator account to install the connect software.

I've got the backup running for the first time now. When it completes I'll be a little bit more comfortable that the network is configured correctly.

• I think looking at this - it may still prove to be a time issue.

Can you confirm the time zone the server is in? It defaults to pacific.

• Both machines are set to central time zone, and even if they weren't the "net time" command properly deals with the time zone issue when used to force synchronization.

Still trying to figure out the issue with this machine.
