The driver provides support for serial ports physically located in an

Ethernet. I have seen that installing the driver is enough to cause the
NTP problem. That is, even if the device is disconnected from the
network and no application uses the serial ports I have the NTP problem.
Currently I know 2 other users which observe similar problems under
Windows Server 2008, one system is 32 bit and the other one is R2 with
64 bit.
Would you mind to let us know exactly which driver/manufacturer causes
this, so we can find out if the same driver causes this for the other guys?

I supply the following information with permission from Comtrol (the
device/driver vendor, www.comtrol.com).
Device: Comtrol DeviceMaster RTS 32-Port
Driver: NS-Link v8.16
I received excellent support from Comtrol after creating my support
case. The problem was solved in less than 24 hours after I submitted my
case. According to Comtrol the root cause is an OS API problem that
Microsoft eventually should fix. The solution for the v8.16 driver was
to delete the driver's ScanRate key in the registry (location for x64
OS: HKLM\SYSTEM\CurrentControlSet\services\rpshsix64\parameters, for x86
OS: HKLM\SYSTEM\CurrentControlSet\services\rpshsi\parameters). Comtrol
will soon release an updated driver that fixes the problem permanently
without requiring the registry change. They will then also post
additional information on http://forum.comtrol.com/.
