Error "System error 5 has occurred" trying to set the system time using NET TIME on XP

Gurus,

I am NOT an administrator of my Windows XP SP3 workstation. BUT I do have
rights to change the system time. I am able to set the time on the machine
causing the Control Panel Date/Time applet. But if I try to set it using
the command line, I get an error. Any ideas why?

C:\>net time \\dim8300 /set /y
System error 5 has occurred.

Access is denied.

I suspect the problem is you lack permissions on the remote computer. Do you
get the same error with:

net time \\dim8300

You need local admin rights on that machine. Spin, are you a domain admin? If so, does your domain admin account work?

My case is similar but:

when I put on Windows XP computer commmad:

net time \\another_comp /set /yes

it works.

But, if I put the same command over 'at' command:

at 10:45 /INTERACTIVE cmd /k "net time \\another_comp /set /yes"

when the execution starts, it says:
System error 5 has occured
Access id Denied

I both cases I put command as a user with administrator privileges.
Any suggestions?

«at» runs commands under «NT AUTHORITY\SYSTEM» account (until you change this behavior). You have to use

at 10:45 /INTERACTIVE cmd /k "net time \\another_comp /set /yes /user:<username> <password>"
