I think the readme mentions some minimum requirements. But as with any
client/server system with a SQL backend, IMHO, you want the server machine
to have a good amount of RAM (SQL loves RAM ), strong network, decent
CPU, and fast disks. If the files you typically deal with are quite large,
then the network & disk speed will probably be the bottleneck before CPU. A
lot depends on your data and how your designers work. Sorry for this
somewhat non-answer, but I don't think there is any magic bullet that works
for everyone.
A lot of issues around installing the server seem to involve anti-virus
(make sure it is off), firewalls (make sure port 80 is open), and IIS
permissions (the default configuration shouldn't have any issues in Windows
Server 2003).
Hope this helps somehow,
