Event ID 5722 in SYstem logs on Windows 2008 R2 domain controller

Hi All

We have a single domain with a number of a 2008 R2 DC's, we also have 1 2003 DC still floating around so we are still at windows 2003 DFL.

On one of my 2008 DC's I am seeing a number of errors for netlogon (pasted below)  I had a quick Google and it implied it was when you have a trust with NT 4 domains which we do not.

The machines referenced in these errors are all Windows 7 Pro in the same domain

Anyone have any idea why these are happening?

You have to  update you domain functional level to Windows 2003 native mode(from the mixed mode)
Try running
Nltest /server:ComputerName /sc_query:DomainName

Based on the fact you indicated these are win7 domain members it is likely the machine account may need to be reset by rejoining the member computer to the domain.

The abaove log indicates that secure channel of the cleint computer is broken and you need to rejoin the client computer to domain to fix the same as suggested by becraig.Also ensure correct dns setting on DC and client as this:http://abhijitw.wordpress.com/2012/03/03/best-practices-for-dns-client-settings-on-domain-controller/
