Help! Can't save or export anything.....

For me, blender will not save blend files or export models ( .obj’s) and gives me console window error like this

its something to do with the way blender is trying to find the right path to save to
We have a window 2003 server, and we are on a domain network(?)
Ive tried to export and save to My C drive too but just get this sort of error as well

Help!?

try only saving to a network drive, not \somepc… etc.

Not sure if this is supposed to work or not

is a network drive a letter - like z: or something - like then stuff you see when you open the small dropdown menu

above are screenshots of what happens when I try to access our network server
ps - are there any image hosting sites that don’t have suspect adverts?
