Synchronizing clocks on Windows-based IMPAX
systems
(Topic number: 6752)
5.
If the system time on the Application Server and the image server (ASPFTP server) differs, the
authentication tickets provided by the IMPAX Client are rejected by the ASPFTP server and image
retrieval fails. You must configure the IMPAX systems to automatically synchronize their system
time with a common server and remain synchronized.
Note:
Also ensure that the time zone for the computer is set correctly to indicate the time zone where
the system is located.
The instructions that follow use the synchronization feature built into the operating system. When
configured, Windows Time Service sets and synchronizes the system time with a standard time
server.
Synchronizing Windows servers to an external time source
(Topic number: 58717)
Synchronize the Windows Server 2008 R2 servers on your network to an external time source to
ensure that image data streaming operates correctly.
CAUTION!
Serious problems might occur if you modify the registry incorrectly. These problems might
require that you reinstall your operating system and we cannot guarantee that these problems
can be solved.
We recommend that you back up the registry before you change it, so that you can back out
the changes, if necessary.
To synchronize Windows servers to an external time source
1.
To open Registry Editor, select Start > Run, type regedit, and click OK.
2. To change the synchronization server to NTP, in the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\Type
subkey, change the REG_SZ value from NT5DS to NTP.
3. To specify if the local machine is a local time server, in the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config\AnnounceFlags
subkey, change the REG_DWORD value to 5.
