Our infrastructure team have bigger things to worry about right now than the network time being 2 minutes out (2 mins slower than external reliable sources). However, the time being wrong really bugs me and the more anal retentive members of our department.
Can we fix this? Yes we can! I know we can because I've done it before. My machine currently synchronizes to "time.nist.gov", i think. At least that is the value in the registry under HKLM\SYSTEM\ControlSet001\Services\W32Time. What I know for sure is that it is within a second of several reliable time servers. My colleagues machines match the network.
After I last rebuilt my machine (approx a year ago) I made some changes to get the time synching correctly but can't for the life of me remember how!
I know this is pretty similar to this question, however I have a slightly different angle on it. Maybe a little reverse engineering of the syncing machine will help us?
Background: I (and my anal-retentive colleagues) are all members of the Domain Admins group and have local admin right to our boxes We cannot change the Domain or DCs in any way. We each have unrestricted access to the internet.
So far tried: Cloning the registry HKLM\SYSTEM\ControlSet001\Services\W32Time to the other machines - this failed
