We need a bit more info - what stage are you at?
Assuming a default SME install and a working network card in the windows box, it goes along the lines of:-
BTW please bear in mind, I am not abke to connect to my SME box from here, so this is all from memory
1) Configure your Windows network card to use an automatically assigned address - reboot - check that it has the correct address with 'ipconfig' (from a DOS window);
2) Using a web browser, connect to the SME box at
http://ipaddressofSMEbox/server-manager (might be https, can't remember);
3) On the SME server manager web page, find the option to change the workgroup, and make it something sensible (win default is just WORKGROUP, but its up to you);
4) On the win PC, set the workgroup to the same as the server - reboot (probably - it will tell you);
5) You should now be able to browse the network, see you SME server, and the primary i-bay. If not, try getting a DOS prompt up and enter:-
net show \\ipaddressOfSMEServer
Do all this, and if it still doesn't work, post back with details of where you got to and what errors you receive.
HTH,
Ade.
