Hello

Windows 2003 FFL and DFL, I recently had to move the PDC role from the
configured DC that is the time server to another DC. How important is it to
keep the PDC role on the DC that is the time server?

By default, the DC with PDCemulator role is the time server for all
other DCs and clients in that domain. Unless you configure this
willingly otherwise, you should be good with that.

If you can asure that time is pretty good synced among all DCs, you
should be good with that configuration.

Cheers,
Florian

Thanks Meinolf. I moved my PDC role and the old DC still thought it was the
time server.
Running w32tm /config /syncfromflags:domhier /update fixed that.
