Most of these issues can be fixed at the network
hardware layer.
A. Make sure you are using switches for your servers.
Make sure all your server network cards are HARDCODED
for 100 FULL. Make sure your switch is HARDCODED for
100 FULL on the switch and all ports.
B. Move to switches on the clients. Take all the
clients that are 10MB and move them to a dedicated
10MB switch. Move all the 100 MB clients to dedicated
100 MB switches. Hardcode the clients and the
switches to 100MB FULL.
Optional Step: Download the latest network card
driver for all your systems and make sure your
switches have the latest firmware update.
C. Move SQL Server to dedicated box and verify you
have SQL optimized. (Search google for "optimize
SQL") Make sure the SQL Server is set to "Network
Applications" on File and Print Sharing Properties.
If you insist on running MSDE you can simply move this
to a dedicated workstation instead of server. The
point is that it's dedicated (aka...not performing any
other duties).
D. Switch to AD (Mixed mode for now). Have at least
two AD Controllers. Split the FSMOs and AD Integrated
DNS on both controllers.
E. Use GPO to lighten the Profiles (REDIRECT all the
folders you don't require in the roaming profile).
F. Make sure users are NOT saving any documents,
files, etc... to their Desktops. They should be
mapping a Home Directory on a dedicated file share for
this purpose. This will slow your logon time
significantly.
This will solve most of the problems you described.
