I have a program which causes this error on a particular users server,
it works fine on loads of other servers.

"Library not registered: System.DirectoryServices"

The line of code that causes it is:

DirectoryEntry Root = new DirectoryEntry("IIS://localhost/w3svc")

Im guessing some com+ has been unregistered?

Ive checked the user definately has IIS installed, does anyone have any
ideas?

Thanks
Brian Norman
