Server Roles

I just want a bit of advice please

I have W2K3 server running on a Standalone. It is hosting E2k3, is AD, File Server and Print Server. My network was only originally for 5 PC's but is growing and is now upto 15 PC's.

I am concerned that the performance, may suffer because everyone is accessing one machine.

I have just installed a gig LAN card in the server which I am hoping will help a bit, but how many PC's can I have before I need to put the File server on a seperate machine?

Or will my system be fine, am I panicing over nothing?

You're probably panicing over nothing.  Have you determined a baseline?

Microsoft sells Small Business Server 2003 which includes Exchange, possibly SQL, and sharepoint and can handle 75 users.

It does depend what you do with the server and how powerful it is, but I had a Pentium 3 dual 550 Xeon handling file services for 600 users without any issues.

Domain controllers don't generally use much resources, nor does print serving.  EXCHANGE can use a lot, but we handled 300 users on a single pentium 500 with 512 MB RAM without complaints.

Thanks.

So if I have 15 users all accessing.

A P4 2.4ghz 512mb with a 4GB partition as a page file, running Exchange 2003 and as a file server should be fine. As well as AD and Print Server.

Personally, I think your pagefile is a little excessive and you should upgrade the server's RAM.  Double it to 1GB.  Then shrink the page file to 2GB.  You should be fine with that setup for many users to come.

you should be fine for starting. when you are finished installing setup a performance logging to see if some part of your system is a bottleneck. probably the RAM will be but you will see it from the performance logs.
