How to get a standalone Windows 7 installation to synchronise time (NTP)

Question

I am trying to get my Windows 7 Professional machine to synchronise time correctly. This laptop is not a member of any Windows domain.

If I try to go to the clock settings, Internet Time tab, and click on "Update Now", it tells me that an error occurred. Misc. commands / output from my system is below.

What else can I try?

w32tm /monitor /domain:time.windows.com

GetDcList failed with error code: 0x8007054B.
Exiting with error 0x8007054B

w32tm /query /configuration

Warning:
Reverse name resolution is best effort. It may not be
correct since RefID field in time packets differs across
NTP implementations and may not be using IP addresses.

Solution

Mine works fine. The only real differences I could spot if I ran w32tm /query /configuration was that I don't get anything with (policy), and rather than type nt5ds, I get ntp.

Sorry, I don't know much about how to fix it, but hopefully that may be a starting point.

Wow, just wow... That is exactly the information that I needed. I've been looking for an answer for so long, I had given up. Thanks so much. Just to be clear as to how I resolved this: technet.microsoft.com/en-us/library/bb490845.aspx Default options - NTP. Used on computers that are not joined to a domain. - NT5DS. Used on computers that are joined to a domain. For some reason, mine was set to NT5D5, not NTP. I changed it in gpedit.msc > Computer Configuration > Administrative Templates > System > Windows Time Service > Time Providers > Configure Windows NTP Client.
