Network Connection

[Sarah]

Really just wanting some advice on problems encountered
connecting home & office computers. Details of systems
(both running Windows XP Pro)
are:- Home Pentium III, 598 mhz, 256 mb of ram
Office Pentium 4, 1.8 Ghz, 512 mb of ram

Problem is speed of connection from home to office. Can
connect OK but takes forever to bring up office screen.
Is it possible home computer is not powerful/fast enough?

Any ideas would be appreciated.

Thanks
