The path specified cannot be used at this time

When I opened my IIS manager (on a server with SharePoint 2007 installed) today and tried to connect to the localhost (which had always been possible in the past, without any changes done to the server), I suddenly got the error "The path specified cannot be used at this time". The solution for this is quite simple luckily... Just go to the services on your server and restart the Windows SharePoint Services Timer service. Then refresh your IIS manager and everything should be back to normal again!
