Sciface error #28 (Insufficient space to complete

System

Hi Folks,
I'm receiving this error message when I try to do any operation on our TS box (TS 5.5.2 SP5 with OD 5.6 SP1, DD 5.6 SP1, MT3.5 on Win2000). I've check the disk space and we are fine on that. Also, I've tried with different including Administrator (admin and master) as well and get this error, so it doesn't matter who I'm logged in as.

Sciface error #28 (Insufficient space to complete operation)

I've searched through the Forums and Devnet with not luck on information about this error.

Any ideas?

Thanks In Advance,
Mukesh
