time sync? - RESOLVED

I would like to be able to sync the time on my computers with a server on the network. I cannot use the NET command as some computers reside on a domain and others in a workgroup.

Is there a way to accomplish this with V.B. Can I connect to a server on the network and copy it's time to the local machine?

I believe http://www.analogx.com/contents/down...etwork/ats.htm allows you to manually change servers. Hope that's enough

Thanks for the info, but I've found a API call to do it.

Cheers.

I was reading one of your posts regarding time syncing:

I was wondering what was the API Call you found to accomplish this?

Thanks
