When I attempt to set the time as follows:
NET TIME \\127.0.0.1 /SET
it works correctly.
When I attempt to set the time thus:
NET TIME \\local-ip-address /SET
I get the error message:
System error 5 has occured.
Access is denied.
I've verified that the following Group Permission is in effect and applies for the user in question:
Local Computer Policy + Computer Configuration + Windows Settings + Security Settings + Local Policies + User Rights Assignment + "Change the system time"
The Windows Time Service is started.
(both probably obvious because the loopback works)
"local-ip-address" machine has "Enable Windows NTP server" group permission enabled.
The error occurs regardless of whether the Firewall is enabled or disabled.
Windows XP SP3, Workgroup networking. A different client machine in the workgroup works, no problem.
Is there another Group Policy or Registry value that applies here?
Thanks in advance for your time and consideration.
