How do I increase my "buffer size"?

Archived from groups: microsoft.public.windowsxp.configuration_manage (More info?)

Have tried to increase buffer size as many photos are not
uploading to my business server. How can I do this. I
got some instruction to "right-click" the title bar, and
either click Defaults or Click Properties, then go
to "layout tab" and under Screen Buffer Size specify
settings of width & height...however, when I do this,
the "layout tab" doesn't come up or show. Any help here?
