+:!: If you  get the error **''The computer did not resync because no time data was available.''**, try a reboot of the DC and **check that NTP traffic is permitted in the firewall** (UDP/123).
 If your time is off by too much (more than 3600 seconds), you'll have to set the time manually with the Date and Time applet.

 ===== Virtual Machines =====
+FIXME Need verify this statement:
 The most accurate way to keep guest operating system time synchronized with real time is probably to use the **VMware Tools** or **XenServer Tools** time synchronization functions.
+==== Citrix ====
+FIXME Need verify registry entries
+{{ :networking:windows:vm_time_sync_disable.reg.zip |Citrix Registry Entries for PDC}}
+These registry entries disable time sync to the virtualization host (drift) when using Citrix Tools and allow NTP to work normally.
