Question : Current time on computer and current time on network are different.

To access our company servers, I would remote-in (RDP) to the box and gain control from my work desktop.  Our server is located a couple of hours away from the office and driving there would be my last option.

Anyway, I control three of our server, x.xxx.x.11 (domain-a virtual serverVM), x.xxx.x.12 (exchange-VM), (x.xxx.x.13- host box + backup device).  When I try to remote logon to the .13 server I would get this message, "The current time on the computer and the current time on the network are different."  The rest of the servers  (.11 and .12) i am able to log in no problem.  I even tried remoting to the the .13 from the .11 but no success.   I checked the time using the command line net time \\x.xx.x.11 and net time \\x.xx.x.13 and found a difference of 5 minutes.  Now i don't know how to remotely fix the differences.  
I found a command line that  would syncronize to gov and millitary standards but they did not change the differences ex.  net time /setsnt:time.nist.gov then net time /setsntp:\\x.xxx.x.11 .  but to no avail.

when i typed the following command line:  net time /querysntp
I get My current SNTP value: NAS   (which is the server i cannot connect to).  

the functions are fine, i just need access to that particular server for maintenance purpose.  

Answer : Current time on computer and current time on network are different.

net time \\x.x.x.13 /set /yes
