I've got an IIS server that is running a bit low on diskspace on the C: drive; I've moved the W3SVC logs from c:\windows\system32\LogFiles to another drive, but there is also a big HTTPERR folder there that I'd like to move somewhere else. How do I do it?
Microsoft have details here but the summary is:
Go into the registry and amend
Then you restart the HTTP service (net stop HTTP, net start HTTP) and then start any dependent services - eg W3SVC. The HTTP service (http.sys) does not appear in the services MMC, so you have to use a command line to start/stop it.
