In 1995, Microsoft introduced Windows 95. This pretty spelled the DEATH of just running some .EXE from a LAN mounted hard disk.
Today, most programs will required REGISTRY entries, DLLs in your SYSTEM and more.
What you ask is a nice idea, but (Windows) progress has made such an idea fall flat and die.
I'm not exactly sure how to ask this question so please bare with me. I was wondering what would be involved with having a central server or whatever it is called so other computers in my house can log into it (or just be networked) and basically use the programs. An example would be using the Outlook .PST file which would be stored there. I could then access the same email from any computer in the house. I am not even sure if this type of setup uses Windows Xp or something else offered by Microsoft. Since I am not sure of the terminology to search for on Google, I was hoping someone here could point me in the proper direction. It is just something I was thinking about researching and possibly doing but i would like to see what is involved first. Thanks for your help.
