company configuration

Hi,

we use a company configuration on a domain server,

now I've defined:    _USTN_INSTALLED_CONFIGURATION=B:/Connect/Configuration/ #signum       in the main msdir.cfg  in the program folder.

Is this the right place to define this, or is there a better way?

second problem:
while we are in the office, the Bentley data is on our B:\ drive,
home-working: use a VPN connection to the server, B:\ drive is connected,
on the road: we have a local limited copy ( of the "configuration directory) on the laptop

haw to set up the cfg  (what is the best place & cfg file)  to ask:      " if    B:\  is connected  : use this B:\ directory      else:   use the local configuration
