This post is part of a project to move my old reference material to my blog. Before 2012, when I accessed the same pieces of code or general information multiple times, I would write a quick HTML page for my own reference and put it on a personal site. Later, I published these pages online. Some of the pages still get used and now I want to make them available on my blog.

By default, Windows Server 2000 only allows a certain number of concurrent connections. If users try to access your site while the connections are maxed out, they will be given an error. You can remedy the situation by buying more CALs from Microsoft, then changing your server’s settings to allow more connections.

Increase Maximum Supported Connections

1. Buy Client Access Licenses (CALs) from Microsoft

2. Click Start, Control Panel, Licenses

3. Click Add Licenses

4. Type the number of new licenses

5. Click OK

6. Check I agree…

7. Click OK

Check Live Concurrent Connections

It may be useful to see the number of live connections to your server.

1. Click Start, Settings, Control Panel, Administrative Tools, Performance

2. In the right pane, right-click the blank gray space

3. Choose Add Counters…

4. In Performance object, select Web Service

5. In Select counters from list, select Current Connections

6. Select All instances
