Because of repeated network problems, the time service has not been able to find 
a domain controller to synchronize with for a long time. To reduce network 
traffic, the time service will wait 960 minutes before trying again. No 
synchronization will take place during this interval, even if network 
connectivity is restored. Accumulated time errors may cause certain network 
operations to fail. To tell the time service that network connectivity has been 
restored and that it should resynchronize, execute ?w32tm /s? from the command 
line.
