Well, topic states it,

we've got a new office setup, so far only approx 20 PC's.
All rolled-out through 1 sys-prep image without zen-agent,
novell-client etc.

All pc's identical both hardware and bios ( custom bios used for all)
And the Win7/64 bit installation should be identical since it's one
single image copied to each pc before rolling out.

And, all connected through the same switch, all ports/auto/no flow

Still, a couple of PC's have TERRIBLE performance with remote viewing
through Zen10, the rest works fine.
The pc's that works bad through Zen/remote do NOT have issue when
using them over RDC....

Any ideas ??
