Does any one know of a tool that could pull the NTP information from every windows server in a domain? I want to make sure that all of the 100+ servers I'm in charge of are all pointing to the same place.

Thanks!

The syntax of this command is:

NET TIME
[\\computername | /DOMAIN[:domainname] | /RTSDOMAIN[:domainname]] [/SET]
         [\\computername] /QUERYSNTP
         [\\computername] /SETSNTP[:ntp server list]

So (assuming you've got a domain admin account handy), you need only script the NET TIME command against a list of servers.

Personally, I prefer PowerShell.  The following assumes you have a list of your servers in a text file (servers.txt).  Here's a quick-n-dirty...

$result = ""
gc C:\Users\me\Documents\servers.txt | 
% { 
    $winsvr = "\\" + $_
    $result += "-----"
    $result += $winsvr
    $result += net time $winsvr /querysntp
}
Out-File C:\Users\me\Documents\results.txt -InputObject $result -Encoding default

Open in new window


This will produce a file that looks like this...

-----
\\SERVER01
The current SNTP value is: time.windows.com,0x1

The command completed successfully.

-----
\\SERVER02
This computer is not currently configured to use a specific SNTP server.

The command completed successfully.

-----
\\SERVER03
This computer is not currently configured to use a specific SNTP server.

The command completed successfully.


Hope that helps!

hi try this
for /F "tokens=1 delims= " %%s in (servers.txt) do for /f "tokens=*" %%x in ('reg query "\\%%s\HKLM\SYSTEM\CurrentControlSet\Services\W32Time\Parameters /v NtpServer^|find /i "REG_SZ""') do echo %%s;%%x>>output.csv

Open in new window

create a new text file past fallowing code save as "run.bat"
create a new text file servers.txt and provide list of server in it
open cmd and run run.bat
it will create a file called output.csv you able to open this file in excel for batter view

code Example  
----------------------------------------------------------------------------------------------------------
D:\>for /f "tokens=*" %x in ('reg query HKLM\SYSTEM\CurrentControlSet\Services\W
32Time\Parameters /v NtpServer ^|find /i "REG_SZ"') do echo %hostname%;%x

D:\>echo localhost;NtpServer    REG_SZ  time.windows.com,0x1
MYPC01;NtpServer     REG_SZ  time.windows.com,0x1

D:\>

I'm not all that familiar with PowerShell but I will tinker around a bit. I also do not have a list of servers. I could make one pretty quickly though. What would the list look like?

One server name per line. If all the servers are in the same domain, and DNS is working as expected, just the hostname should do.

SERVER01
SERVER02
SERVER03

If needs be, you can use the FQDN...

SERVER01.mydomain.local
SERVER02.mydomain.local
...

This was a perfect explanation and worked flawlessly. For having almost no scripting experience and zero powershell experience, I was able to use this solution quite easily.

Thanks!
