Given that we run a Samba server on Solaris (and on Linux) and only use a 
Windows 2000/2003 server for authentication and profiles, I did this 
from the client.  FileMon is one of a great set of utilities from
www.sysinternals.com which reports all file accesses, time-stamped.

Since we now have established that Thomas meant the default configuration
(not just base), 4 secs is tolerable and it looks like a server problem
(rather than a network problem). I would defragment the volume in case the
R\library directory has got badly fragmented.

For the record, R 2.0.0 took 2s to start on a Linux 500MHz Celeron box 
over our network, and takes 0.62s to start on a 2.6GHz P4 under Windows XP 
with a fast local disc (and about 0.38s on the same box under FC2 Linux).
