Saving Powerpoint Files

[Debu]

I have a Powerpoint File (2.65MB) with 166 slides. This
file also has macros and some links associated with it.
When I am inside the corporate network, I can save the
file (both locally and on the network drive) without any
problems. When I am outside the network connected via VPN
(either with dial-up or high speed) I am unable to save
this file (neither locally nor on a network drive). It
just freezes the laptop.

Any ideas?

Thanks
