Apple Remote Desktop Delay/Lag in Connecting to Control

Hi,

All computers are on the LAN with Cat6 cabling.

Recently ARD has been lagging by 10-15 seconds when connecting to view or control a client.

For the previous 9 years the ARD lag time was just a second or so.

I guess I noticed the change starting about a month or so ago.

Any advice?

Thanks,

b.
