Why can’t I see IIS on my SharePoint Server?

Recently I noticed the Application Event Log of one of our internal SharePoint servers filling up with 6482 errors. Another added irritance was that the Web Sites treeview in IIS would not open, instead giving an error “The path specified cannot be used at this time.”

The solution that worked for me was to Restart the Windows SharePoint Services Timer service. After that, the errors ceased and IIS functionality was restored!

Extending the 50-site limit in SharePoint's Site Directory

Today while at work I was working to clean up our intranet’s site directory in SharePoint. I noticed that the Site Map (a Table of Contents web part) was only listing 50 sites. Since I knew there were more and that this was probably the result of some inherent limit to the web part, I dug around and found this post¬†(no longer working)¬†which explains how to modify your web.config.

It basically boils down to adding a property DynamicChildLimit=”XX” to the following entries in the siteMap providers section of the web.config file, where XX is 0 (no limit) or whatever numeric limit you decide. By default it is – you guessed it – 50.

(The web.config file to modify is usually located in C:InetpubwwwrootwssVirtualDirectories80, with the last portion being whatever port number MOSS is running from):
